If you do not see the Confirmation task in your Task list, it means that there was a problem in the process–the most probable place is the SendMessage workstep. Check the following:
Is the JMS Adapter configured correctly? Maybe you did not specify the mode correctly–selecting Send/Receive makes your adapter wait for a reply that never arrives. Check the JMS queue name–is the JNDI name correct?
Is the queue accessible? Depending on the application server you use, make sure that the queue is accessible from the context where Business Process Server is running. For some application servers, you may need to restart the server before the queue becomes accessible.
If the previous steps do not correct the problem, check the OEBPS_HOME\logs\managedadapter.log file. Additional tracking information about the JMS Adapter operation may be available there.
