The classpath suggestion worked!
Thanks Charles.

Subject: RE: Newbie: HelloWorld will not work for me
Giampiero,
I originally had a similar problem where Tomcat could not locate my
HelloWorld portlet. However, I don't believe I was seeing the same
exception as you. I was seeing a class not found for the HelloWorld
portlet. I finally resolved the problem by doing away with my CLASSPATH
all
together. Apparently my CLASSPATH settings were confusing the class
loaders
of Tomcat.
Hope this helps.
Chuck

Subject: Newbie: HelloWorld will not work for me
I have tried everything in every mailing list about the subject.
I have just re-installed Tomcat and have written HelloWorldPortlet.class
which does not have any package associated with it. Then I copied it to
WEB-INF/classes. This didn't work, so I tried putting the class into a
jar and putting the jar file into the WEB-INF/lib directory. This also
didn't work. I haven't done anything with the classpath that isn't out
of the ordinary (ie CLASSPATH contains usual entries).
I can't think of anything else. I have tried it all. Any suggestions
would be very welcome.
This is the error that I get:
