Hi all, First sorry for posting this in the site without previous discussion in the list, in future ideas section. In our department, we use jboss server as primary application server product, a jboss server ships jboss cache as cache solution, and hiberbate of course. We have extended xwkicache and we have now a jboss cache implementation, due a high workload we have not tested it. Are any issues doing this to pay atention? What about usign jboss hibernate session factory? Regards.
