Accessing application activity information [message #1514883]

Can anyone suggest a way to access the application activity related information such as the current OID (Activity instance id). I can see that id in the debugger but have not found an API to retrieve it in a plain java application.

I want to use that id to do relocation within the process using the WorkflowService.performAdHocTransaction.

The use case is when an application activity (plain java application) fails, that application activity should be aborted and the process instance should be set back to the first available relocation target found.

Albert,

checkout the predefined process data in the Eclipse modeler.
Using a Spring Bean instead of a POJO and looking up information in the context may also be of interest. For instance:

SessionContext sessionContext = SessionContext.findSessionContext();
		QueryService qsService = sessionContext.getServiceFactory()
				.getQueryService();

		ParticipantInfo pInfo = qsService....

Robert,

Thanks for your reply.

What do you mean with the predefined process data.

In the meantime I found out it is not possible to relocate the process from the (failing) application activity due to incompatible state (state running).

Another approach I am trying is to catch the exception in the process and start a new process for the administrator to handle the exception (i.e. a failing webservice call to send data to a remote system). But catching the exception makes the failing activity to complete. I've tried to hibernate it with an extra event action but than I cannot reactivate it. Do you have a suggestion on how to handle this.
