I should have seen this before posting another similar issue. I have the same problem with jboss-common-core.jar with Jboss Portal 2.7.2(Base Jboss 4.2.3) , Spring 3.0.0.M3. When included, my other datasource, queue looks in Spring Context file are not recognized. i been struggling for last two weeks to get around this problem. However after removing the factory class from jar file as you have suggested in the JIRA issue, when I bind the cache to JNDI, I am getting the following exception | | caused by: java.io.NotSerializableException: org.jboss.cache.invocation.CacheInvocationDelegate | at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081) | at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1375) | at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1347) | at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1290) | at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1079) | at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:302) | at java.rmi.MarshalledObject.<init>(MarshalledObject.java:92) | at org.jnp.interfaces.MarshalledValuePair.<init>(MarshalledValuePair.java:65) | at org.jnp.interfaces.NamingContext.rebind(NamingContext.java:508) Can you tell me what is wrong with this ? Appreciate any help in this regard. thx & rgds, Srinivas View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257969#...
