OSB 12C :WSM-06404 error in a WS-AT web service call on OSB 12c

When executing a WS-AT web service operation the following error is thrown:

<WSM-06404> <The resource pattern "ResourcePattern [absolutePortableExpression=/WLS/osbdomain/|#MODULE|WS-Client({http://schemas.xmlsoap.org/ws/2004/10/wsat}WSAT10Service#ParticipantPortTypePort,wls)]" does not uniquely identify the subject.>

It was caused due to transaction is being left open even after the message was consumed.

Solution:

Use @TransactionManagement(value=TransactionManagementType.CONTAINER) instead of @TransactionManagement(value=TransactionManagementType.BEAN) in the web service.
