[jboss-user] [JBoss Portal] - Portlet Container 2.0B1 : NullPointerException at PortletReq

[dfloch]

Hello,

I try to use Portlet Container 2.0 (bundled with Tomcat6) with Spring Portlet mvc. I made a war with the phonebook-portlet example from Spring and I referenced the application into the simple-portal war. I modified the demo3.jsp like this :
....
   <jbp:layout1>
            <jsp:attribute name="leftcol">
               <jbp:portlet name="Foo" applicationName="bar"/>
            </jsp:attribute>
            <jsp:attribute name="rightcol">
               <jbp:portlet name="phonebook" applicationName="SpringPocPortlet"/>

               <jbp:portlet name="HeaderPortlet" applicationName="samples-basic" id="header-portlet"/>

            </jsp:attribute>
   </jbp:layout1>
....

I got the following exception :

Any idea where the problem come from?
