Trying to get a portlet to work [was Re: Administration Portlet doesn't work]

Okay I'm getting flustered.

I've followed the configuration instructions for pluto-portal-driver-config.xml, including the portlet-app element (even though the other portlets don't seem to need this). Checking on the source code, what I'm seeing is that the portletRegistry probably doesn't have an entry for my portlet. I'm back to the same thing as ever - why doesn't Pluto recognize my portlet?

Does anybody have any ideas? I'm totally at a loss.

Well I wasn't able to get the admin portlet to completely recognize my portlet but I did manage to create a page with my portlet on it by editing pluto-portal-driver-config.xml. 

I now get a blowup to the effect of what's below. I've implemented doView, doEdit, doHelp however.

Subject: Re: Administration Portlet doesn't work

Okay thanks for letting me know. 

I tried 1.1.0 and the admin page works fine. Now I only need to deploy my portlet.

I created a war file and successfully deployed it into the tomcat instance that's part of the bundle. But I'm trying to figure out how to get Pluto to notice it. Note that I have yet to successfully deploy a portlet in anyone's portlet container and I'm really not sure what I'm missing. 

I've noticed that when I look at other portlets there are often Servlets mentioned in web.xml that seem to parallel the portlet itself. I've never seen anything in the Portlet Spec about that. Should I be writing some servlets? Just trying to hello world right now.

If there's a better mailing list for my questions please feel free to direct me to it...

Thanks for the update.

This is a known issue with version 1.1.1.  It has been fixed in the 
trunk and 1.1.2 is due out shortly.  If you'd like, role back to 1.1.0 
and you should be fine.
