I've deprecated track-connection-by-tx and introduced interleaving element and managed attribute in the code. Also corrected the examples in connector/example-config. The remaining is the schema connector/resources/schema/jboss-cf.xsd and the dtd. Both look inaccurate to me. E.g. track-connection-by-tx in the schema is of boolean type and must always be present. track-connection-by-tx is the dtd is declared as EMPTY but must always be present! So, it seems like none of them was actually used (or used only when it didn't fail)? I would fix the track-connection-by-tx in the current versions of schema and dtd then create another version of both w/o track-connection-by-tx but with interleaving. Does this sound right to everybody? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4172530#...
