You are right, there is only one, the other one in that list is a jboss-ejb plugin. Take a look at the source for the plugin, it is not particularly complex and I know the author is lurking around here somewhere. I would suggest that you do one of two things - 1. Create an interceptor, probably identical to the one in the plugin. If you have troubles, bring them to the list, we'll help. 2. Create an object factory implementation that creates actions using your container's semantics. Again, if you have troubles, bring 'em back here, we'll help you.
