It is a singleton class loaded by Spring. cache.registerClassLoader() is called inside initialization method. anonymous wrote : 2) Are you setting up a scoped loader repository in jboss-app.xml? I would like to, but for now I have that commented out. anonymous wrote : 3) In jbossweb-tomcat55.sar/META-INF/jboss-service.xml, what are the values for "Java2ClassLoadingCompliance" and "UseJBossWebLoader"? <attribute name="Java2ClassLoadingCompliance">false</attribute> | <attribute name="UseJBossWebLoader">false</attribute> | anonymous wrote : 4) You say that after you set up marshalling "Now the cache is not getting replicated." Please be more specific -- what is happening? I added an item into "test" in one cache node in the cluster. I try to do a lookup on the other cache node, and it fails. I also was looking from JMX console. I invoked "printDetails". I see the item in one node, but not in the other. I have also tried manually putting and item from the JMX console. I don't see this item when I invoke "printDetails" on the other node. Another exception. When I invoked remove method from JMX console, I am seeing "javax.management.IntrospectionException: Failed to find PropertyEditor for type: org.jboss.cache.Fqn" Thanks much!
