Correct. anonymous wrote : I haven't tried adding the clustered true node in the jboss.xml file. I don't have such a file. | Are you referring to the "standardjboss.xml" file? | | If yes, where do I add this node? If not which file are you referring to? The jboss.xml file is the jboss-specific deployment descriptor that you add to your EJB jar's META-INF directory. The schema can be found in the docs/schema/jboss_5_0.xsd file in your JBoss AS distribution. A simple example: | <?xml version="1.0"?> | <jboss | xmlns="http://www.jboss.com/xml/ns/javaee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee | http://www.jboss.org/j2ee/schema/jboss_5_0.xsd" | version="3.0"> | <enterprise-beans> | <session> | <ejb-name>ExampleStateful</ejb-name> | <jndi-name>ExampleStatefulRemote</jndi-name> | <clustered>true</clustered> | <cluster-config> | </session> | </enterprise-beans> | </jboss> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203699#...
