Hi Dan it is always helpful to let us know which version of Jetspeed your using.
Thanks, Philip

Hello,
I tried to deploy the simplest example that I found on the jespeed site
and I encounter an error. I tried another example and I received the
same problem:
Cannot create Portlet instance HelloWorld for Portlet Application
helloworld
And I don't know what to do. I browsed all over the web and i didn't
find anything that helped me. So I write to you.
I attached the little project.
I don't know if you can download the attach and i paste you the file here:
