Subject RE: Building in Eclipse
Date Fri, 05 Jun 2009 17:02:47 GMT

Hi,
 I tried setting up with eclipse and was successful too.. :) 
I exactly followed this link given by Michael 

[1]
http://cwiki.apache.org/confluence/display/openjpa/Building#Building-Eclipse

But there were a couple of points that were not mentioned.. 

1. M2_REPO - variable need to be created in eclipse which points to the
local repository.
2. Under OpenJPA-kernal, the jjtree and javacc folders were added to
exclusion filters.. Instead I added them to my source folders..

I didnt understand why they were added to exclusion fileset.. is there any
harm in having them under source folder?

Thanks and Regards,
-Srini
