after go through the logs, i noticed that if i deploy the WAR alone, parent context is found during creation of the Portlet ApplicationContext. In another way, if i deploy the EAR, the parent context seems like not found.

Before
2010-10-12 14:26:29,486 INFO [DispatcherPortlet.init(98)] Initializing portlet 'presetPlans'
2010-10-12 14:26:29,509 INFO [DispatcherPortlet.initPortletBean(263)] FrameworkPortlet 'presetPlans': initialization started
2010-10-12 14:26:29,515 DEBUG [DispatcherPortlet.createPortletApplicationContext( 327)] Portlet with name 'presetPlans' will try to create custom ApplicationContext context of class 'org.springframework.web.portlet.context.XmlPortle tApplicationContext', using parent context [Root WebApplicationContext: startup date [Tue Oct 12 14:25:52 SGT 2010]; root of context hierarchy]

After
2010-10-12 14:15:27,013 INFO [DispatcherPortlet.init(98)] Initializing portlet 'presetPlans'
2010-10-12 14:15:27,104 INFO [DispatcherPortlet.initPortletBean(263)] FrameworkPortlet 'presetPlans': initialization started

how i can solve the problem?
