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?
