I haven't looked at the latest petstore examples. Just a hint: the examples
that come with the j2ee-ri use a persistence management that tries to be
good in an environment without connection pools. The way they do it
does not allow you to use XA-database access, you have to use JDBC-database
access due to transaction restrictions (there is nothing special about this
with jboss, the examples also fail if you use XA database access in
weblogic). JDBC database access in jboss-2.0_FINAL has some bugs though
that I have reported lately.
