It seems to be a bug, please could you open a Ticket in jira and  
provide additional information for that?

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:

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

The NoClassDefFoundError exception is thrown from within drools code, so
it's obviously in the classpath. The problem appears to be with the
mechanism used by drools to load it's own code.
