Hi there, I did exactly as you (sonicfab) suggested: I created a CacheManager singleton and I initialize/destroy cache in a ServletContextListener. Pay attention during redeploy: if I redeploy a webApp using TreeCache in WebLogic 8.1 it hangs during cache shutdown; everything works as expected if you stop/start your webApp. Bye Piero View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4031044#...
