I have an instance of Drools running inside a webapp deployed on Tomcat. The rules have been compiled ahead of time and are loaded in with:
InputStream is = PolicyRuntime.class.getResourceAsStream(name);
DroolsObjectInputStream in = new DroolsObjectInputStream(is);
Package p = (Package) in.readObject();
When run outside Tomcat it loads fine, when run inside Tomcat I get:
java.lang.NoClassDefFoundError: org/drools/base/extractors/BaseObjectClassFieldExtractor

I've tried adding DroolsObjectInputStream.class.getClassLoader() , PolicyRuntime.class.getClassLoader() and Thread.currentThread().getContextClassLoader() to the constructor of the DroolsObjectInputStream but none had any effect.
Thanks
Jesse
