[rules-users] Drools examples don't run

[赵侃侃]

Hello,

I checked out the latest source from svn repository. It compiled OK and
imported the example projects to my eclipse workspace but the examples run
with error.
The two example projects are namely drools-examples-drl
& drools-examples-fusion.

org.drools.examples.pacman.Main gives the errors:

Exception in thread "main" java.lang.NoClassDefFoundError:

org.drools.examples.broker.Main gives the errors:

Does anyone experience the similar issues and know how to fix that?

Best Regards,
Kevin
