Can you post your web.xml file ?

I have just tested the RssPortlet successfully:

pageregistry.xml:

    <fragment name="RssPortlet" type="page" >
        <navigation>
            <title>RssPortlet</title>
            <description>RssPortlet Description</description>
        </navigation>
          <fragment name="row1" type="row">
             <fragment name="col1" type="column">
                  <fragment name="p1" type="portlet">
                    <property name="portlet" value="11.0"/>
                  </fragment>
             </fragment>
         </fragment>
    </fragment>

portletentityregistry.xml:

    <application id="11">
        <definition-id>RssPortlet</definition-id>
        <portlet id="0">
            <definition-id>RssPortlet.RssPortlet</definition-id>
        </portlet>
    </application>

web.xml:

Subject: Re: portlet deployment problem

Hi, thx for reply.

Checked portletcontext.txt and there are no empty lines. below is the full stack trace and relevant parts of pageregistry.xml and portletentityregistry.xml. I've tested with other portlets and pluto renders them fine w/o exceptions, but when trying latest version of RssPortlet, getting a NullPointerException. Any hints or ideas?

Exception:

java.lang.NullPointerException

Having the same problem. Did you figure this one out?

portletcontexts.txt includes /RssPortlet,

but still receiving NullPointerException.
