Paul,
We will need more details about your setup to be able to diagnose the
problem.
What is exact version of m2e and wtp that you are using?
What operation fails with this exception?
If you can provide sample project, please open a bugreport in JIRA [1]
and we will have a look.

For some reason the isEJBArchive is throwing a NPE (Error below) but this is
a WAR project so what is happening? Am I right in thinking this is a problem
with the M2Eclipse integration with WTP?
Cheers
