Hi Simon.

Recompiling won't help. I'm not sure, but I'm assuming that this is a
classloading issue. You had said that under other conditions the
service invocation worked correctly. Did that also involve your
version of spring? What does your CLASSPATH look like?

One thing to test would be to remove your version of spring (2.0.8)
try again. This shouldn't be a problem unless you are doing
something in particular with classloaders.

Best wishes,
~J.

P.S. What version of OMERO are you currently working with?
