[jbosscache-users] Trying transactions on WebSphere 6.1

Hey guys, I have a WebSphere 6.1 app server and I use RAD (eclipse based) for my development. I got the basic operations with the JbossCache (POJO) working, however I am having trouble with the transactions. I realized I have to set the "javaAgent" to instrument my classes, but I am not sure how to do this in Websphere 6.1. Where in the console (or file) can I go and set this? thanks
