No clue what's wrong, and I couldn't figure it out.
I decided to deploy the WAR manually, using the manager, and pointing it
to the WAR file. That worked fine, which lead me to another solution.
Since I'm using tomcat6, I switched to the tomcat6 plugin, and that
works. I just don't get it. I'm fairly certain I did not change my
environment at all, as it's been working for 2-3 weeks. The maven plugin
wasn't updated since 2013.
The following now works.
mvn install tomcat6:deploy
As does...
# the old plugin, which consequently runs tomcat 6 as well.
mvn tomcat:run
But, as to why it suddenly stopped working on me, causing me hours of
frustration, I'm at a loss. I was deploying yesterday, and it just
suddenly wouldn't work anymore. Reverting back many git revisions, even
to where I first started using openjpa, and it still doesn't work. I
was going to use "git bisect", but I couldn't find a good revision to
work with. :(
I don't normally give up, but I'm giving up, cause I have a solution,
it's just not the ideal solution because I wanted to know what was
wrong; especially since this happened so suddenly.

Sorry I'm not much help, but I have no idea what's going on. Please let us

Hi Rick,
I'm using Java 1.7 and tomcat 6.
I'm really not sure what is wrong. I checked out old revisions, which I
know could at least deploy to tomcat, and they do not work either now.
That makes me wonder about my environment, but I don't know what it could
be. I did review the xerces libraries coming in using the maven -X
parameter, and they are all 2.4.0.
It's just all very strange. I did, unfortunately, have open ended
versions on some of my plugins in my poms, which I fixed yesterday, but I'm
wondering if it's possible that something was released, which messed it up
on me. I'm going to go find out which plugins those were, and see if I can
push back the versions used and see what happens.

I've been googling, and trying to debug this for awhile, and just don't
