Hi jaikiran, Problem solved. Thank-you. I have added the annotation and that solved the current problem... I have a new problem and I'll start a new thread for that. By the way, the documentation needs to be updated for JBoss 5. The documenation refers to PoolClass and it appears that JBoss 5 uses "Pool" and not "PoolClass". @PoolClass (value=org.jboss.ejb3.StrictMaxPool.class, maxSize=5, timeout=10000) Also the package name for StrickMaxPool has changed to: org.jboss.ejb3.pool.StrictMaxPool The annotation that I am using is: @Pool (value="StrictMaxPool", maxSize=35, timeout=20000) Thanks very much!
