I am migrating struts 2 application to portal. By default struts 2 has internally struts2portlet plugin. when I add portlet.xml and changing the struts.xml, the struts 2 application is migrated to portlet.

But If I add portlet-api.jar in the lib folder, it throws PortletInitializing exception. Any solution?

Is there any jar could be added for getting PortletContext n other details about portlet in struts2portlet application?

Thanks in advance
