When using Message Driven Bean while trying to migrate the application from OC4J to Weblogic an issue is faced with MDB as singleton service.
This message driven bean original deployed to a singleton OC4J (only one instance will be activated in the whole cluster at any time).
You would like to use the singletonService feature to simulate this requirement in Weblogic, but you found that the singletonService and the MDB are not working as expected.
