[rules-users] drools-spring drools-grid-impl dependency

[Tommy Odom]

I tried modifying the drools-grid-impl JAR file to remove the persistence.xml file, that is apparently not the problem because I still get the same persistence unit error.  I'm not sure what the problem is but I can switch between my two branches and the only difference between the two is one has maven dependencies set to drools 5.2.0.M2 instead of 5.1.1 (and a few process listener & planner class updates to fix compilation errors).

I'll have to do some more debugging later when I have some more time.

In my WAR file I have my persistence.xml under WEB-INF/classes/META-INF/.

Since drools-spring needs access to the GridNode it has a dependency on drools-grid-impl which in turn has dependencies on hibernate & JPA 1.0 and includes a persistence.xml file.  I was able to work around the hibernate and JPA 1.0 dependencies using maven exclusion rules but it appears that the included persistence.xml is causing problems with my own configuration locating its persistence unit.
