class loader problem
I am having trouble when re-deploying a seam application on Jboss 4.2.
It works fine when the server is first started, however if I redeploy it I will get the following error eventually (usually after 1-5 redeploys):

I am using two XA postgres datasources, and I have a feeling that there is some kind of problem with this setup, as it is always org.postgresql class that fails to load. Any idea what I could be doing wrong?
