[GAP] error launching cmuConsumer.jar from the command line

[Jeff McCullough]

Just to let anyone know, in case they run into something similar, I discovered the issue. In specifying the -jar option I was also specifying the class path found in the jar manifest. That class path is not overruled by the command line class path options. This is the classpath that is found in the jar file:

Class-Path: ../../conf/ activemq-all-5.7.0.jar cmuConsumer.jar commons-cli.jar commons-logging.jar subject.jar ../../dist/lib/grouper.jar

The easiest work around is just specifying the main class which in this case is edu.cmu.grouper.changelog.consumer.ConsumerMain along with an appropriate class path. Obviously, there are other options as well. The main point is knowing how the jar command works in regard to the -jar option.

Cheers,
Jeff
