Hi, You might be interested by "DynamicImport-Package" (MANIFEST.MF) in your drools plugin, to allow it to dynamically access your classes that are located in another plugin. These configurations depend a lot on your plugins architecture/dependencies.

All the classes needed from Drools plugin are found and I can initialize the ruleBase unless I try to add an import statement for a java class into the DRL file. When the DRL file gets parsed by Drools I get this strange exception. Don't know why the class cannot be found. I assume the class is loaded by means of reflections in Drools. This means when the class is on class path it should also be found or do I forget something important???
