Description of problem:

While trying to build DTGOV for FSW ER7, it failed to build due to not being aligned correctly with the community platform BOM.

I have attached a patch file that needs to be applied to the dtgov repo.

The fixes are minor and have to do with aligning with the community BOM.
Can you please apply these changes and have them available for the next tag please , whenever that is due.

3 Files are affected, these are:

1) dtgov-war/src/main/resources/META-INF/persistence.xml
Class TaskEventImpl has moved to a new package

2) dtgov-workflows/pom.xml
There has been a GAV change to org.drools:drools-maven-plugin, it is now org.kie:kie-maven-plugin

3)dtgov-ui-war/src/test/java/org/overlord/dtgov/ui/server/servlets/MockHttpServletRequest.java

This file was missing implementation of abstract methods for javax.servlet 3.0 API.

This is due to the fact that in dtgov-ui-war/pom.xml you have a dependency to javax.servlet:servlet-api:2.5 , however if you look at the community platform bom https://github.com/jboss-integration/jboss-integration-platform-bom/blob/6.0.0.CR3/ip-bom/pom.xml#L1831

You should be using the BOM version instead of your own, similarly with jsp and other artifacts but that was the only test that was affected.
