Thank You Manik I read wiki page about migration from 1.4 to 2.x Now I replace jboss cache jar in jboss as 4.2.2 in order to use jbosscache 3.0.1 Using CacheMode=Local it is working. But an exception occurs starting the war "10:57:07,984 WARN [TomcatDeployer] Failed to setup clustering, clustering disabled. NoClassDefFoundError: org/jboss/cache/TreeCacheListener" My web.xml has the "distributalbe" attribute.. but the TreeCacheListener doesn't exists anymore in Jbosscache 3.0.1. I believe that the I cannot change it.. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4198044#...
