I guess I had same issue.
At first - check your jar and make sure it is there.
Then make sure you don't override default Bundle-ClassPath.
And finally - try to specify full path ([package]/'RuleFile.drl)

Actually I've started with placing rule on a local disk and specifying path to it (/home/user/rule.dlr) and then made some debugging.

Hello all,

I develop an OSGi Drools bundle in Apache Felix. I access to this bundle
with a web service client because I use Apache CXF- DOSGi. Everything is
right here.

But when I try to run this bunle with my client, I get a
FileNotFoundException when I call to the services that I want to use.

This is the error trace:

*java.lang.RuntimeException: java.io.FileNotFoundException: 'RuleFile.drl' c

       at
drools.services.impl.DroolsServicesImpl.readKnowledgeBase(DroolsServi

The rule file is in the same classpath, and it is inside the .jar file

Somebody can help me??

Thanks in advance!!
