Thanks for the timely response as this was critical. I started with testing by adding the annotation and it works fine. Then, removed the code and edited the xml file and even then it works fine (no passivation). I edited the file both in clustered/nonclustered and passivation is being stopped. However, I am not sure the editing of the xml file will cause other problems. Following are the changes I made. 1) First test: stopping passivation for all beans. Added the following lines to domain = "Stateful Bean". anonymous wrote : '<'annotation expr=&quot;!class((a)org.jboss.annotation.ejb.cache.Cache)&quot;&gt; | @org.jboss.annotation.ejb.cache.Cache (org.jboss.ejb3.cache.NoPassivationCache.class) | '<'/annotation> 2) Second test: stopping passivation for a specific bean (only one stateful bean in def package) . Added the following lines to domain = "Stateful Bean". anonymous wrote : '<'annotation expr=&quot;!class((a)com.aaa.bbb.ccc.def.*)&quot;&gt; | @org.jboss.annotation.ejb.cache.Cache (org.jboss.ejb3.cache.NoPassivationCache.class) | '<'/annotation> Can you please confirm the correctness of the changes made to the xml file?
