Hi, I couldn't get a success. My settings are: web.xml <session-config> | <session-timeout>15</session-timeout> | </session-config> JBOSS_HOME/server/default/deploy/ejb3-interceptors-aop.xml: <annotation expr=&quot;!class((a)org.jboss.annotation.ejb.cache.simple.CacheConfig) AND !class((a)org.jboss.annotation.ejb.Clustered)&quot;&gt; | @org.jboss.annotation.ejb.cache.simple.CacheConfig (maxSize=100000, idleTimeoutSeconds=900) | </annotation> JBOSS_HOME\server\default\conf\standardjboss.xml: <container-name>Standard Stateful SessionBean</container-name> | ... | <cache-policy-conf> | <min-capacity>50</min-capacity> | <max-capacity>1000000</max-capacity> | <remover-period>900</remover-period> | <max-bean-life>900</max-bean-life> | <overager-period>300</overager-period> | <max-bean-age>600</max-bean-age> | <resizer-period>400</resizer-period> | <max-cache-miss-period>60</max-cache-miss-period> | <min-cache-miss-period>1</min-cache-miss-period> | <cache-load-factor>0.75</cache-load-factor> | </cache-policy-conf> I also changed the timeout time to 16 and 14, but all the three timeout time (14, 15, 16) gave the same exception:javax.ejb.EJBNoSuchObjectException: Could not find Stateful bean: 5c4o04-q5szlm-evd5usub-1-evd8gijv-3n. Did I do something wrong above? I really appreciate more guidance. Thank you. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3991528#...
