If you are running Glassfish and using JMS (e.g. a Message Driven Bean), you probably saw already the following error in the log files: DirectConsumer:Caught Exception delivering messagecom.sun.messaging.jmq.io.Packet cannot be cast to com.sun.messaging.jms.ra.DirectPacket.
The error is caused by directly embedding the JMS-Host into Glassfish v2 - it can be easily fixed in the admin console:
- Open the admin console: http://localhost:4848
- Select: Configuration -> Java Message Service node in the tree on the left side.
- Change the type from "Embedded" into "Local". The doc says:
"Choose LOCAL (the default for the server-config configuration) to access the JMS service on the local host. The JMS service is started and managed by the Application Server."
- Restart Glassfish
