I have code that supports an embedded DS in JBoss.  The following imports that were valid in 1.5.1 no longer appear to be valid in 1.5.2.
some time ago I brought the server-sar to make it compatible with the latest 1.5 series builds. I did this by abandoning the approach of configuring everything from MBean attributes and using a configuration loaded from a standard server.xml instead. Let me know if you are interested in this code.
