Guvnor doesn't use OSGi.
The stack trace suggests the JAR you are has a dependency on OSGi:-
org.drools.guvnor.server.contenthandler.ModelContentHandler.getImportsFromJar.
The remainder of the stack trace relates to trying to load the imported
class.

Hi all,
I have installed Guvnor 5.3.0-Final on a fresh Tomcat 7.0.12. I am able
to import existing rules I have, however when I try to upload my fact model
I get an error in the localhost log file:
SEVERE: Servlet.service() for servlet [AssetFileServlet] in context with
path [/guvnor-5.3.0.Final-tomcat-6.0] threw exception [Servlet execution
threw an exception] with root cause

I am attempting to upload a jar with all dependencies it uses (which
includes JPA annotations and JAXB annotations). I have verified that the
jar contains all its proper dependencies. This message seems to indicate I
am missing some OSGi jar or something that I would have expected to be
delivered with Guvnor. Do I need some sort of global libraries for OSGi to
run Guvnor or to use my model when it has these external dependencies in
the jar?
Any help on this is greatly appreciated.
Cheers.
Mike Key
