org.osgi.framework.BundleException: The bundle "org.drools.eclipse_5.2.0.v20110116-0638-H14 [46]" could not be resolved. Reason: Missing Constraint: Require-Bundle: org.eclipse.jdt.junit; bundle-version="0.0.0"  

This error is caused because your bundle is attempting to load a bundle with the symbolic name of "org.eclipse.jdt.junit", any version. Try deploying that before your application, and it should allow you to proceed to the next error.
