"No JTA UserTransaction available" errmsg thrown by Atomikos/JTA standalone app

I did succeed in upgrading a functioning standalone desktop Java/Spring3x/Hibernate3x/Maven/MySQL5x/Eclipse app
from using Hibernate for my ORM to JPA2.

Now I'd like to upgrade it further from using JPA2 to JTA. I chose Atomikos
for my external transaction manager as JOTM is no longer supported in Spring 3.x .

Here's what I have so far:

pom.xml


ApplicationContext.xml


persistence.xml


and my simple app
TestQueries


Problem is when I execute TestQueries I never get to point C -


I can't figure out why I'm getting these errmsgs, my beans for transactionManager and its properties look ok.
the pom excludes a few transitive dependencies that cause conflicts.

Can anyone spot what's wrong/missing/extraneous? It must be something fiendishly subtle.

TIA,


Still-learning Steve
