Loanbroker ESB should use modern version of OpenEJB

Here you go http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/openejb/openejb-core/3.1/

OK, tried with 3.1, transitive deps are much cleaner than 2.1.1, I get a different JNDI-related error now:

Looks like there's some other version around. Can you check the mvn dependency:list and dependency:tree outputs?
