Patrick,
This occur because the web.xml file for the sample portlet is incomplete
-- try replacing the contents of the web.xml file with the following:

Subject: Unable to run WSRP4J portlet examples
Hello there
I've been trying with last night codeline (fresh check out from SVN) to
run the examples provided before trying my own.
To no extent....
I compiled everything ok with Maven 1.0.2, then running the Producer on
Tomcat 4.1 and the SwingConsumer with JRE 1.5 (note that it does not
work with 1.4 - it complains about a missing
"org.xml.sax.ext.Attribute2" class).
I'm getting a NullPointerException error as described at the bottom of
this mail...
Then I had a look at Pluto's container code to understand a bit better
what's going on.
Basically the PortletInvoker gets a ServletDefinition NULL object from
the PortletDefinition object.
Any idea why ?
Did someone ever face the same problem ?
Is this a configuration issue or a bug ?
any help appreciated
tx
Patrick
