I hope someone can provide me some feedback into this error. I've done some research on this error, but the recommendations do not work.

What I have done is created a portlet in Sun Java Studio Creator and have it working on the Sun Server. Now I moved the portlet over to Liferay. I've added the two Liferay deployment descriptors within the war file. Now I am trying to deploy the portlet in Liferay and it fails! :-(

What I have found within the Sun forum is the appearance that the application server/portal has duplicate jar files (jsf-portlet.jar). When I search Liferay and remove the dublicate portlet jar files from the project the application still fails with an error--no class definition found. When I remove the duplicate jar files from Lifray so only my portlet project possesses the jar files, I still get the same error!

Here is the error:

Sounds like the same problem as at http://www.liferay.com/web/guest/community/forums/message_boards/message/117168

Joerg:

Thank you so much! Okay, I've removed that error...only to find more... :-( The root problem was Sun Java Studio Creator throws a jsf-portlet.jar file into the project's library. When I remove the jar file and put it in the common/lib as suggested by your earlier post, the classloader issue was gone! Amazing! :-)

However, this surfaced more errors which are outside my project.

This is the first error I am getting now when I startup liferay:

Thanks for your earlier suggestions and for your time in assisting me in using Liferay. Any comments regarding these errors would be greatly appreciated.

Hi Russ,

I have never encountered this error, so I probably can't help you. The only very vague guess I have is that one Lucene instance tries to obtain a lock while it is still hold by another one. This could point to a classloader/deployment problem again when 2 Lucene instances are deployed. But that's really only an idea.
