Between enterprises, BPEL enables easier and more effective integration with business partners. BPEL stimulates enterprises to further define their business processes, which in turn leads to business process optimization, reengineering, and the selection of the most appropriate processes, thus further optimizing the organization. Definitions of business processes described in BPEL do not affect existing systems, thereby stimulating upgrades. BPEL is the key technology in environments where functionalities are already or will be exposed via Web services.

[JMSClientExceptions:055144]Destination must be a topic

ERROR:- <Error> <oracle.soa.bpel.engine.ws> <BEA-000000> <got FabricInvocationException weblogic.jms.common.InvalidDestinationException: [JMSClientExceptions:055144]Destination must be a topic, JMSModule!mycompany.dev.queue.Process.ErrorMessage.Routing CAUSE:-  The issue occurred due to incorrect setting of JMS Adapter Outbound Connection Pool. "mycompany.dev.queue.Process.ErrorMessage.Routing" is a queue created in JMSModule. However the outbound connection pool created at JMS Adapter to interact with this queue has IsTopic set as TRUE. This means it is searching for a TOPIC by the name "mycompany.dev.queue.Process.ErrorMessage.Routing" and not a queue. SOLUTION:-  If you are creating JMS Adapter Outbound Connection Pool for QUEUE, set isTopic= FALSE. If you are creating JMS Adapter Outbound Connection Pool for TOPIC, set isTopic= TRUE.
