Hi , I ran kie-drools workbench 6.1 beta on websphere liberty 8.5.5 and gives manifest file related errors as below. I tried to add jars but spent all the time just find that again it asks for other jars in loop with different versions of same jars. Need help on this.. Error: The manifest class path avalon-framework-4.2.0.jar can not be found in jar file file:/D:/Program%20Files/IBM/Liberty/usr/servers/guvnor/apps/drools6/WEB-INF/lib/fop-0.95.jar or its parent.
