[Objectbridge-jdo-dev] Re: Objectbridge-jdo-dev digest, Vol 1 #62 - 5 msgs

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi all,
I am new to this mailing and I am really intrested in a good open source JDO implementation. So I am looking forward to participating in the development of this project. 

I started off with dowloading the ojb-0.9 version and ran tutorial1 and tutorial2. I encountered a small problem when running tutorial2. A "Invlaid column _ID" SQLException is being thrown on Edit and Delete use cases. I changed the code in ULDeleteProduct and UCEditProduct classes to use "ID" instead of "_ID" in the OQL. Then when I rebuilt the tests and ran tutorial2 it worked fine. We may have to fix that problem.

But anyways...I will be spending the next few days understanding the code...

Uday
