Configuration Management

This chapter explains the configuration concept of Axon.ivy and describes the configuration editor and the various configuration types.

Configuration Management

Axon.ivy allows for individual configuration of many of its features, specifically for the following:

The specifics of the above described configuration types are explained in more detail in a separate section.

A configuration is always associated with a type (the type of object that it configures) and with an unique name. When applying a configuration to an object, only the name of the configuration must be given, because the type is defined by the object being configured.

By consistently defining and using the logically named configurations instead of setting properties individually on each configurable object you can later easily change or redefine the looks and behavior of the application in a single place.

All configurations can be created, edited and deleted using the Configuration Editor.


In Axon.ivy, each project has its own configuration database.

Lookup of any configurations is performed by an (type, configuration name) request. If the look-up of such a configuration fails for the current project then the configuration databases of the required projects are searched with the same query recursively. With this mechanism, configurations can effectively be shared among projects.

Since the current project is always asked first for a specific configuration, you can easily overwrite configurations that come from a required project, simply by redefining them locally (on the same type with the same name).


When creating a new project with the New Project Wizard you will be asked if default configuration content should be created for the new project. You should always disable this option if you're creating a project that will be dependent on other projects. If you don't disable it then all of the default configurations that are defined in the base project will be redefined automatically in the new project (and thereby shadow the inherited configurations), which may lead to unexpected behavior of the application.

If you unintentionally forgot to disable the option in the wizard you can still manually delete all configurations that have been created in the content database using the Configuration Editor at a later point of time.

Configuration Editor

The configuration editor is used to add/edit/delete configurations in the hierarchically organized configuration database of a project.

The configuration editor consists of different parts that are described separately below:

  • Configuration Tree

  • Configuration Editor Area (with header showing type/name of currently selected configuration)

  • Multi-Language Selector (not for all configuration types) This part is only visible if you have enabled the multi-language feature in the Axon.ivy preferences. Axon.ivy preferences > Configuration > Show Multi language Configurations

Generally, configurations are selected from the tree on the left hand side of the editor and edited in the details area on the right hand side. Modification of the configuration tree is performed with various actions that are available from the tree's context menu.


Axon.ivy Project Tree > double click on the entry in the tree.

Configuration Tree

The configuration tree shows the currently defined configurations inside a hierarchically organized tree. Configurations () are associated with a configuration class or configuration type () which in turn are logically grouped in a hierarchical folder structure ().

Only configuration nodes can be edited in the tree, the structure of the configuration database (i.e. the folders and types) is given by the system and cannot be changed.

The following operations are available from the context menu of the various configuration tree nodes:

Add configuration

Adds a new configuration below the selected configuration class node.


Renames the currently selected configuration.


Renaming of a configuration does not update the objects that currently use the configuration with the old name. I.e. objects or scripts that used the old configuration name may not produce the expected outcome anymore, because the specified configuration does no longer exist. Typically this leads to the fallback of using the default configuration of the respective configuration class.


Deletes the currently selected configuration node.


Deleting configurations may lead to the same effects as renaming them. See warning above for a description of the possible consequences.


Copies the selected configuration into a new configuration with a name prompted from the user.


Please note that you don't have to paste the new configuration, it will be pasted automatically next to the selected source configuration, because a configuration is always associated with exactly one configuration class. It is not possible to copy a configuration of type A to a type B.


Refreshes the configurations below the selected node.

Configuration Editor Area

The editor area shows a different editor depending on the configuration type (also called configuration class) of the currently selected configuration. The individual editors are described in the configuration types section.

The title bar of the editor area shows the type (i.e. the configuration class) and the name of the currently selected configuration as <ConfigClassName>/<ConfigurationName>.

Multi language Configuration Selector

Enable the multi selection configuration by setting the flag in the Axon.ivy preferences.

Some configurations can be defined in multiple languages because they contain language specific settings. The validation configurations may have to validate input differently if it is entered in another language.


Use CMS references for the error message property in order to support multiple languages.

The language selector is shown only for configurations that support multiple language values per configuration. Use it to select the language of the configuration that you want to edit.


Add new language value

Adds a value in a new language to the currently selected configuration. The contents of the last shown value are copied as initial content to the new configuration value.

Delete language value

Clicking on this button removes the currently shown value from the set of values for this configuration. Only works if more than one language value are defined.

Renderers Configuration

Renderer Configurations are used for specific content objects when they are rendered, the result is then displayed on the client browser.

Smart Table Configuration Editor

The Smart Table Configuration editor is part of the Configuration Management. See Configuration Editor for more information. A Smart Table Configuration can be added by using the add configuration function. The name is used in the Smart Table Content Object Editor for choosing a specific configuration.

The Smart Table Content Editor

Figure 8.1. The Smart Table Content Editor

Table Settings

The HTML attributes settings for the table and the caption HTML elements.

Header Settings

The HTML attributes settings for the table header group (thead element), the header row (tr element) and the header cells (th elements).

Body Settings

The HTML attributes settings for the table header group (thead element), the header row (tr element) and the header cells (th elements).

Footer Settings

The HTML attributes settings for the table body group (tbody element), the body rows (tr elements) and the body cells (td elements). Here it is possible to define different configuration for the rows and cells depending if they are displayed on an even or odd row position. The cells can also be different if they are in a even or odd column, in the first or last column or if they are in the column which is actually sorted. The first and last column settings does override the even or odd columns settings and the sorted column setting does override all other settings.

Sort Settings

Enter the text which is displayed in the header if a column is sortable. Then ascending and descending values are shown. When a column actually is sorted then the sorted ascending or sorted descending values are shown.

Page Selector Settings

Enter the format of the page selector, where it is shown (default: bottom) and the values displayed for the first, previous, next and last page to show. For the format there are the following possibilities:

{|<}Link to jump to the first page is shown with the value configured with the setting "First page".
{<}Link to jump to the previous page is shown with the value configured with the setting "Previous page".
{123}Links to jump to every page is shown with the page number.
{>}Link to jump to the next page is shown with the value configured with the setting "Next page".
{>|}Link to jump to the last page is shown with the value configured with the setting "Last page".
{n}The number of the actual page is displayed.
{m}The number of the total amount of pages is displayed.
{x}The number of the first showed row is displayed.
{y}The number of the last showed row is displayed.
{z}The number of the total rows in the table source is displayed.

Configuration Types

The configuration database of a project contains configurations for various configurable targets (e.g. widgets, date or time values, input text fields, etc).

The user can define configurations for the following three aspects of an application: formats, styles and validation. Each of those aspects encompasses a number of configurable types (e.g. date or time or number) for each of which an arbitrary number of named configurations can be defined, which can then be referred from different locations in the configuration.

This section briefly discusses the different configuration types and explains the usage of their respective configuration editors.

Format Configurations


Format configurations define how values of a specific type will be rendered when output to the user. Formats can be defined for all the base types of IvyScript, i.e. Boolean, Date, DateTime, Time, Number, and String. All non-null values of those types may be output as formatted strings by calling the format("<format name>") within any script.


panel.label.text = in.selectedDate.format("long");
out.invoice.customerNumber = wsData.customer.format("customer_id");

The format configuration editor allows to specify various ways of formatting for the different IvyScript base type values. The formatting options (described below) vary from type to type; not all options are available on all types.


Format configurations are always language dependent. Just watch the Preview editor area after each selection or option that you enable for an understanding what the effects are for each language.

Format Type

Select a predefined kind of formatting. The selected format kind may be further specified in the editor areas Option, Format Pattern and Format Script (depending on which kind that was selected).


This editor area is only available for some of the Number format kinds. The number of digits for the integer and/or fraction part may be selected (-1 stands for as many as needed). If you select grouping then a group character will be inserted to group the integer digits of the formatted number.

Format Pattern

This group is only available if you have selected the PATTERN format from the Format Type list.

If Pattern is selected as format then this combo box allows for a selection from a number of predefined patterns. Use Script if you'd like to specify your own pattern format.

Format Script

This group is only available if you have selected the SCRIPT format from the Format Type list.

Specify your own format with a script. The value variable will contain the value to be formatted. If you want to specify different patterns for different languages you should use the language selector to create multiple configurations for various languages.

Environments represent different runtime infrastructures. There are two use cases for environments:

  • Staging: Software goes through a software development cycle and is often tested on different environments before it is deployed on the productive environment. Typical environments in this case are "development", "testing" and "production".

  • Multi-Tenancy: If software must meet the multi-tenancy requirement, environments can be used for the individual tenants. In this case the environments would be named after the customer, for example "customer1", "customerX" and "customerZ".

Global Variables, Databases, SOAP Web Services and REST Web Services comes with environment support. Defining an environment value in these features is always optional. For example: If you have multiple environments and using Global Variables, you don't have to specify values for all environments. If one is missing, it will fallback to the default value.


The environment editor is part of the Configuration Management. By using the add configuration function a new environment will be added. The name of the environment is the name of the configuration. If you delete or rename an environment, all associated values will be removed. For example, environment specific values in Global Variables are deleted.

Change environment for simulation

It is possible to change the active environment for the simulation by setting the environment in the preferences.

Change environment at runtime

The active environment can be specified in app.yaml. If no environment is active at all, the default environment will be taken.

To fulfill the requirements of multi-tenancy you may need to use the following api. The active environment can be set on case, session or application. If the environment is set on multiple levels, the level with the smallest scope is taken.

ScopeAPI name)
Sessionivy.session.setActiveEnvironment(String name) name)

Global Variables

Global Variables acts as global constants which can be used in your application. Global Variables are simple Key/Value pairs which can be specified by the developer. Some examples for global variables are:

  • Company data (name, address, contacts)

  • Simple Rule Values (e.g. credit account)

  • Path values for saving files

  • Path values for 3rd party systems and some other variables


The global variable editor is part of the Configuration Management. See Configuration Editor for more information. A global variable can be added by using the add configuration function. The name of the global variable is the name of the configuration.

Default value

Provide a default value of the global variable. This can be a Number or a String. This value will be used if you access the global variable in the application.


Provide a description of the global variable.

Environment settings

In this section the default value of the global variable can be overridden/new assigned for the specific Environment.

Access global variables in IvyScript

In order the access the Global Variables in your code a new environment variable var was introduced in IvyScript which provides a comfortable access to your defined variables. This approach has the advantage that, if global variables are removed developers will immediately informed in which process element the variable was used.

Database Configuration

This chapter deals with the database configuration. To use databases in your business or User Dialog processes you need to define some database configurations first. After you have configured the databases (data sources) you can use them in your process steps. The process steps references only the database configuration ids. So you can use different database configuration settings on your productive server.

Database Configuration Editor


The Axon.ivy database configuration editor lets you configure the databases you use in your project and the extending projects.

The Database Configuration Editor

Figure 8.2. The Database Configuration Editor


Add a new database configuration

Add environment

Add an environment configuration for the selected database. Select one or more environments for the environment list. For new environment configurations the standard configuration is taken. Please note, existing environment configurations will be overridden, if you add an environment twice.


Remove the selected database configuration

Test Connection

Test database connection. A dialog shows the result status if the database can be connected or not. In the case of a failure the reason will be displayed


Opens a SQL editor in order to set up SQL Statements. The SQL Editor displays the result in a result table


Axon.ivy Project Tree > double click on the Persistence label.


All Database Configurations

A list of all database configurations defined in this project. A red or green icon indicates the result of the automatically executed connection test.

Database Connection Configuration

Shows the state of the automatically executed connection test.


Select the type and driver of the database you use. Some often used and tested drivers are shipped with the Designer. Additional drivers can be added by copying its JDBC driver Jar into the jre/lib/ext folder of your Axon.ivy installation.

The field max. connections lets you specify the number of concurrent connections to your database.

Connection Properties

Specify the properties for the connection to your database.

Additional Connection Properties

If your database needs more information you can use this section to define the additional properties.

REST Clients Configuration

The REST clients configuration contains the definition of all REST services, which can be consumed from a BPM process.

REST Client

A REST client can be referenced by its name or by its universal unique identifier (uuid). The uuid is generated when a new REST client is created and will never change. The name of a REST client is given when a new REST client is created. It can be changed later. By referencing a REST client by its uuid ensures that renaming of the REST client will not break the reference.

Further information about how to use the REST clients can be found in the chapter “Call a remote REST Service”.

Like other configurations a REST client can be configured differently per environment.

REST Client Editor

The REST client Editor allows to configure REST client default and environments configurations.

REST Clients Tree Editor

Shows the REST clients and its environment configurations.

Add Client

Adds a new REST client.

Add Environment

Adds a new environment configuration for the selected REST client.


Removes the selected environment or REST client configuration.

REST Client Details Editor

Shows the currently selected REST client or environment configuration.

REST Client Section

Universal unique identifier of the REST client. The REST client can be referenced by this uuid. Cannot be modified.


The name of the REST client. The REST client can be referenced by this name. Can be modified. Note that references using the name will break if you change it.


Description of the REST client.


The base URI under which the remote service publishes its resources (e.g.

The URI can contain template placeholders which are resolved later by the client user (e.g.{version})."twitter").resolveTemplate("version", "1.1").get()


To consume a REST service running in the same Axon.ivy Engine / Application as the client a set of Axon.ivy placeholders can be used. These placeholders are automatically resolved: {}, {ivy.engine.http.port}, {ivy.engine.context}, {ivy.request.application}.

E.g. http://{}:}{ivy.engine.http.port}/{ivy.engine.context}/api/{ivy.request.application}/my/service

Authentication Section
HTTP Basic

Adds support for HTTP Basic authentication.

HTTP Digest

Adds support for HTTP Digest authentication.


Adds support for NTLM authentication. Optionally, the NTLM.domain and the NTLM.workstation can be configured in the properties section.


The name of the user used to authenticate the client.


The password of the user used to authenticate the client.

Features Section

Adds a feature so that responses in JSON are mapped to Java objects and Java objects in requests are mapped to JSON.

Features List

Shows the configured "features" classes. The classes configured here are registered in the WebTarget using the method register(Class). The classes need to implement a JAX-RS contract interface and must have a default constructor.


Adds a new feature class.


Removes the selected feature.

Properties Section
Properties Table

Properties can customize the settings of the REST client or one of its features.

Client properties

Well known properties of the client are documented here: org.glassfish.jersey.client.ClientProperties.

In order to configure SSL client authentication for a REST client call, you need to specify the property SSL.keyAlias. The value of this alias needs to correspond with a key alias available in the client keystore configured under SSL Client Settings.

JSON properties

The JSON feature knows many properties that customize the serialization from JSON to Java objects and vice versa.

It is for instance possible to read a very complex JSON object with many fields back to a Java object that contains only a subset of these fields. To allow this incomplete but efficient mapping the property Deserialization.FAIL_ON_UNKNOWN_PROPERTIES must be set to false.

Consult the Jackson documentation for a list of all configurable items:


Adds a new property.

Add Password

Adds a new password property. The value of a password property is not visible in the table and is stored encrypted in the configuration file.


Removes the selected property.

Web Service Clients Editor

This chapter describes how web service configurations are organized.

Web Service Clients Editor

Figure 8.3. Web Service Clients Editor

Client Tree

Web service configurations are displayed in a tree hierarchy. The tree editor helps to add and delete existing tree elements (web service groups, web service configurations and web service environment configurations).

In the editor the groups are symbolized with a folder icon. The web service configuration elements are symbolized with a globe icon. On the right side there are buttons offering the following functions:

Add Client

Adds a new web service client configuration.

Add Environment

Adds an environment configuration to the selected web service configuration. Select one or more environments from the environment list.

Add Group

Adds a new web service group. These can be used to structure your service trees.


Remove the current selection.


Entries you want to erase might still be in use. Check all dependencies before removing elements from the tree.

Client Details Editor

Details of currently selected web service configuration node are displayed on the right hand side. In this editor details of an tree element (web service group, web service configuration or web service environment configuration) can be changed.

Web Service Client Section

The following attributes are available in the Web Service Section:


The name attribute specifies the displayed name of a web service configuration. The name is not used as identifier, so it can be changed at any time.


Description of the web service. This field is for documentation purposes only.


Service details and classes will be generated using the WSDL specified here. Please use protocol prefix like:



The library that is used to generate the web service client classes. Unless you have some special reasons to use the older Axis framework, please select Apache CXF. Note that you have to regenerate the web service client classes if you change this setting.

Generate WS classes

After specifying the mandatory fields WSDL URL and Library you can click the Generate WS classes button to read the WSDL and generate client side classes. The generated files will be compiled and packaged into a jar file. The generated jar file will be located in the lib_ws/client folder of ivy project and automatically added to the project libraries.


When you change the WSDL URL, the WSDL itself or the Library setting you always have to re-generate the service classes.

Authentication Section

Configures the authentication that is sent to the remote web service.

The following attributes are available in the Authentication section:


The authentication type to be used. The available authentication types depends on the selected library.


Name of the user used to authenticate the client. Will be stored as a property.


Password of the user used to authenticate the client. Will be stored as a property.


Authentication properties like (username and password) can be overridden in the “Web Service Call Activity” that performs the call to the remote service. On these activities authentication properties can contain scripted/dynamic values.

Features Section

Features add optional functionality to a web service client call execution.


Adds a new feature class to the list. All specified feature classes must implement the JAX-WS standard class or ch.ivyteam.ivy.webservice.exec.feature.WebServiceClientFeature.


Removes the selected feature class from the list.

Properties Section

Properties configure the web service client and its features. Some well known properties are documented here:


Adds a new property.

Add Password

Adds a new password property. The value of a password property is not visible in the table and is stored encrypted in the configuration file.


Removes the selected property.


In order to configure SSL client authentication for a web service, you need to specify the property SSL.keyAlias. The value of this alias needs to correspond with a key alias available in the client keystore configured under SSL Client Settings.

Endpoint URI Section

The following attributes are available in the Ports section:


The list of ports is available after web service client classes generation. (see: Generate WS classes). The content of this list originates from the specified WSDL and is filled with information from the client framework.

Default URI

The URI where the current web service is located. The initial URI is derived from the WSDL. But one can override this setting if the address has changed. It can also be overridden per environment. For instance to route calls during development to test instance of the service.

Fallback URIs

An optional list of URIs. They are used as fallback URI if any error happens during the web service request. The default endpoint will be called first, then the fallback URI in the appearing order. Servers on the list are queried one by one until a successful web service access can be made. You find error messages in the runtime log when endpoint invocations fail. If a service invocation is successful then the process continues as normal.

This list is optional. If this list is empty and no default URI is specified then an exception is raised during the call and the process continues with error handling.

Roles and Users

Role is a widely used term in the computer industry and means a group of users of a certain system which share a common property. This enables an administrator to define configurations for this groups (roles) of users at once instead of defining it for each and every user individually. Axon.ivy incorporates a sophisticated role and user model to support:

  • Authentication - Who may login into Axon.ivy

  • Authorization - Control who is allowed to do what

  • Task assignment - Decide who has to perform a task in a workflow

  • User dependent UI elements - Configure who can see and operate on UI elements

In the following two sections you will learn how to create, edit and remove roles and users and how to link users with roles and vice versa.

Role Concept

The hierarchy of the roles is built upon the principle of specialization. Each child role specialises its parent role(s) meaning that a role Team A always implicitly contains its parent roles. The role Everybody is the root for all roles, all roles specialize this role. For example in the figure below, a member user of role Team A also has the roles Development and Everybody.

Member Role

A Member Role can be added as a child of an existing Role and links to another existing Role. While resolving the role tree, to collect the specializations of each role, the Member Role is handled like a normal child Role. Basically this simplifies the configuration and administration of roles.


The concept with Member Roles allows to create a sub-tree of roles with 'company roles' and a sub-tree of roles with 'permission roles'. The sub-tree of 'company roles' represents typically the structure of the company. The sub-tree of 'permission roles' represents the use or execution permission of a specific part or feature of an application. With a Member Role it is possible to assign a permission to a 'company role' by linking the 'company role' as a member role of a specific 'permission role'.

The following configuration illustrates that users of group First Level and Team B have the permission for Process N and users of both support groups and of the Support Group itself has the permission for Process M.

+ Everybody
  + Support Group
    + First Level
    + Second Level
  + Development
    + Team A
    + Team B

  + Application Permissions
    + Process M
      - First Level (Member Role linked to role 'First Level')
      - Team B (Member Role)
    + Process N
      - Support Group (Member Role linked to role 'Support Group')

Role Editor

The role editor allows to create a new role and to edit and/or to remove existing roles and to structure them into a hierarchy. It can be started by double clicking on the Roles node in the Axon.ivy Projects view.

The Role Editor

Figure 8.4. The Role Editor

The left side of the Role editor consists of a tree showing all the roles in a hierarchy order. A click on one of the roles will show the properties for the selected role on the right side of the editor. The role hierarchy can be manipulated by dragging a role and dropping it at the new place in the hierarchy.


A new role is created as a child of the selected role.


A role is added as a linked member role to the selected role.


The selected role and all its children roles are removed. The user is obliged to confirm the removal. Note that the role Everybody may not be deleted.

Import XML

A .roleconfig file from another project can be imported for convenience reasons.

Export XML

All roles are exported in a XML file with the extension .roleconfig to easily re-use the role hierarchy.


The selected roles are sorted alphabetically, if desired this is performed recursively on the children.


Roles created in the designer are not uploaded to the Axon.ivy Engine until the deployment of the project. They are merged with all other roles in the same application context. Consider that the deployment will fail if the same role exist in more than one project in different role hierarchies.

Test User Editor

Process designers can create, edit and remove test users in the user editor. Users need a password in order to authenticate themselves and they need to be assigned to at least one role. The editor can be started by double clicking on the Test Users node in the Axon.ivy Projects view.


Test users are only used in the process simulation within the Axon.ivy Designer and they are not uploaded to the engine at the deployment. Users for deployed processes on the Axon.ivy Engine need to be created and configured on the engine.

The User editor

Figure 8.5. The User editor

The left side of the editor you see all users with their user names (i.e. login name) and their full names. On the right side the specific properties for the selected user on the left side is displayed. A user can be assigned to several roles and he is implicitly assigned to the parent roles of the roles, he explicitly is assigned to (see Role Editor for more precise details). Additional properties can be added to each user in terms of string key-value pairs and be reused within process steps in IvyScript.


Creates a new user with the specified name.


Removes a user from the list. The process designer is obliged to confirm the removal.


Sorts the user list in alphabetical order.


A .userconfig file from another project can be imported for convenience reasons.

Export XML

All users and their corresponding properties are exported in a XML file with the extension .userconfig to easily re-use the users in another project.


You do not see the user called Developer, because it is a built in user, that belongs to all groups, and owns all rights. The user is meant to be used for testing, so it only exists in the Designer. The password of this user is Developer (in case you would like to log in using IvyScript)

Configuration files

Configuration files are located in the configuration folder under the %AXON_IVY_INSTALLATION% folder. These files you have to edit outside of Axon.ivy, e.g. using a system editor. It is recommended to stop your designer before you start changing these configurations.

There are some configuration files with extension *.xml. These are normal XML files. Meanwhile the *.any files are so called any files. There are a couple of any implementations - so that there is no real standard. The intention behind this is to have an easy to understand configuration with simple structure, and practically unlimited parameter types.


Using this file you can change logging preferences. This files contains a Log4j configuration. Log4j is an open source framework for logging. You can change logging format, logging destination (file, console, etc.), logging level and control which packages should be logged on which level.
