That shouldn't happen, looks like a classpath issue. Also I think you
are on an older version of Drools, please try RC2 and let me know if its
still a problem.

Anyone knows what could be the problem? It is a unit test which runs OK in Eclipse, but fails when running from the command line, even classpath is the same.
Sorry about the lack of details. Have to run now. Will provide more info later if necessary.
Thanks,
