For an alternative, as simple as it seems what I often employ is just generating an id myself using the uuid standard (java.util.uuid or commons-id) and passing that back after login. Or you can do something similar with an ejb stateful session bean. So I just have a wsdl template I use just about everywhere via 'extension base' .
Axis2 also does generate an uuid which is sent in the soap message via ws-addressing. I still typically just handle it myself due to a wide range of integration issues and legacy support - though I am watching the ws-addressing standard as it evolves and all the soap engines support it.
