Still the same error. btw, I set the DEFAULT_ROOT_APP_CONTEXT_JNDI_NAME to the parent cotext name. ( I hope that the right thing to do), in both JndiRootApplicationContextLookup and AbstractJndiContextLoader . Who calls the static lookup method of JndiRootApplicationContextLookup class ? I think the initialize method of JndiRootApplicationContextLookup is missing something. from what I can see, it only sets the value of JNDI_NAME variable . Should it not call the lookup after that ?
