    • Method Detail

      • release

        public void release()
             throws Exception
        Description copied from interface: IProcessExtension
        This method is called before this process extension is thrown away by the process engine. Implementers should release all resource they have allocated in this method, so that the process extension can be garbage collected (Stop all created threads, close all opened files, etc.)
        Specified by:
        release in interface IProcessExtension
        Throws:
        Exception - if bean can not be released

      • start

        public void start()
           throws Exception
        Description copied from interface: IProcessExtension
        On the designer this method is called if the simulation starts. On the server this method is called after the process is loaded and before the process handles the first request. Implementors can use this method to prepare the bean to handle requests (e.g. start threads, allocate resources etc.)
        Specified by:
        start in interface IProcessExtension
        Throws:
        Exception - if bean can not be started

        public void stop()
          throws Exception
        Description copied from interface: IProcessExtension
        On the designer this method is called if the simulation stops. On the server this method is called before the process is unloaded, this can happened if the process model version, the process model or the web application is deactivated. Implementors must use this method to abort all running request.
        Specified by:
        stop in interface IProcessExtension
