"JBPM and Webservice call with callback - please advise" To view the discussion, visit: https://community.jboss.org/message/766579#766579 -------------------------------------------------------------- Hi, I'm quite new to JBPM5, though have worked quite a lot with JBPM4.4. We are investigating if we can switch to JBPM5. I need to create a Task in a bpmn flow that sends a message to an external webservice. Lets call this Task-A. Moreover, the external party must respond (async) within a definable time (for example 1 hour or 1 day...) Only if the external party responds within this time period,Task-A can be completed and the next task can be started. Else a different (error-reporting/fallback) task should be started. If no response arrived in time, Task-A should be marked as terminated/obsolete(?) so in case a response of the external party arrives afterwards, this has no effect anymore. Can you give me any ideas in how to accomplish this? Challenge 1: Creating a callback to complete the Task-A: I found something similar (I think) in an example called "PersistentEmergencyServiceProcess", though I'm not sure it is a good staring point since: 1) this handles about human tasks 2) it has an ActiveWorkItemService.java class which states: * This class doesn't support ksession crashes. The ksession passed to its * constructor must leave through all the process execution. ==> what if the server get's restarted within the life-span of 1 hour or 1 day? Challenge 2: Creating a duedate/timeout on the Task-A: In JBPM4.4 it is quite easy to set a timer (duedate) on a task. How can this be done in JBPM5? I do not see such property on a Task in the JBPM Editor. Challenge 3: How to call an external webservice: Are there any available helper-classes to easely achieve this? Or should I just generate POJO from a WSDL and call this code from a bean? Any advice will be greatly appreciated!
