Thanks, I have resolved my problem. Documentation of JbossCache is wrong anonymous wrote : 5.2. Via JBoss Microcontainer (JBoss AS 5.x) | | Beginning with AS 5, JBoss AS supports deployment of POJO services via deployment of a file whose name ends with -beans.xml. A POJO service is one whose implementation is via a "Plain Old Java Object", meaning a simple java bean that isn't required to implement any special interfaces or extend any particular superclass. After changing -beans.xml to -jboss-beans.xml now I can access my cache ;) JBoss Cache folks are bad guys :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4225325#...
