Error Creating Project

Hi, I was attempting to create a project and I received the following error:

BEGIN:

END:

I have the commons-logging.jar in my installed extensions directory.  Thus, I really don't understand why I'm getting this error message.  If anyone has any ideas, please post to the group and/or send me an e-mail.

Thanks in advance,

-Conrad

Re: Error Creating Project

Posted by Ben Walding <be...@walding.com>.
It may be that you are getting classloader issues (i.e. multiple 
commons-logging versions installed).
I'd try removing commons-logging from your extensions directory.
