The package now has one rule: when eval(true) then System.out.println("It works"); Compiles fine on govner, etc. My rule agent configuration is: newInstance=3Dtrue #file=3D/foo/bar/boo.pkg /foo/bar/boo2.pkg #dir=3D/my/dir url=3Dhttp://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/= foo/test #localCacheDir=3D/foo/bar/cache poll=3D30 name=3DMyConfig When I post to the url (via poster in firefox) I get: Apache Tomcat/5.5.17 - Error report
