Jonathan, I've added the following interface to the JCA SPI in jboss-integration: org.jboss.jca.spi.xa.XAResourceWrapper with the methods getEISProductName() and getEISProductVersion(). So you can depend on this interface for AS-5.0. For AS-4.x support you still need to keep the JcaXAResourceWrapper support. The JNDI name lookup functionality will be added to a MC bean in the new POJO implementation. The user can now get basic information about where to look for the source of the error. Let me know what you think. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4161758#...
