Hi,
I read all your posts and i think you have to do next two points:
1) You need to create a datasource with the XA Driver "Resources >
JDBC Providers > New JDBC Provider" and choose the Cloudscape JDBC Driver XA
2) I think you need to "enable XA" in the Connection Queue Factory of the JMS Resource "Resources > WebSphere JMS Provider > WebSphere Queue Connection Factories > Your Queue Connection Factory".
