Please excuse my previous kludge question.,
Let me start with my first question.
My classes are contained and loaded in a jar from ./common/lib (also tried
./shared/lib). When
the my common class is instantiated by my web application, the
getContextClassLoader
reports WebAppClassLoader .. I've doubled checked to make sure i didn't have
duplicate classes in ./WEB-INF (I don't).
thread = new Thread(this);
log.info("JOpc created a new thread : " + thread.toString());
log.info(thread.getContextClassLoader());
My question is, should getContextClassLoader report WebAppClassLoader?? I
guess I assumed that
it should report something like 'Common'. Am I right to be suspicious about
this?
Thanks,
Scott
