Exception handler scripts are basically Java code, that is invoked if an exception or error occurred during the execution of a process flow. There are three types of Exception handler scripts:

• Service exception
• Process Flow exception
• Invalid data exception

These scripts can be created at the global level (for all the activities in the process flow) or at the activity level (for a specific activity). If an exception or error occurred during the execution of a process flow, the activity level exception handler script is invoked first. If an activity level exception handler script is not created for that activity, then only global level exception handler script is invoked.

• • The class must implement PluginExecutor interface.

    Code Block
    public class <class_name> implements PluginExecutor

    
    

  • The method should accept only one parameter and that must have an object of ExecutionEvent.

    Code Block
    public boolean <method_name>(ExecutionEvent event) throws Exception

    
    

  • The method must be public.

   Script	In this option, you need to define the Java code for the execution of the process flow. Using this option will decrease the execution performance of the process flow.
   Custom API	It is recommended to use this option. Using this option will increase the execution performance of the process flow. In this option, you need to select the class and its method for the execution of the process flow.
