the key to the problem is this line in the error listing: "Caused by:
java.lang.RuntimeException: The Eclipse JDT Core jar is not in the
classpath"
This reference is to the library "core-3.4.2.v_883_R34x.jar" which is
installed by the Eclipse Drools plugin
If you add core-3.4.2.v_883_R34x.jar to your libraries then you won't get
the runtime exception.
