In a Spring-based application with many portlets, if one portlet is added to a page, everything is OK.

But if 2 or more are added in the same page, I get this exception (all portlets):

[com.liferay.portal.layoutconfiguration.util.RuntimePageImpl-1][render_portlet_jsp:154] javax.servlet.ServletException: File "/WEB-INF/jsp/xxx.jsp" not found

See attachment with a Spring sample application including 2 portlets.
