[rules-users] OptaPlanner Guvnor integration

[Bartek]

Thanks for your answer, it helps.
But just after solving one problem I am facing another. When uploading 
my domain facts to Guvnor I get exception (from guvnor logs):

...
  Servlet.service() for servlet AssetFileServlet threw exception: 
javax.enterprise.event.ObserverException
...
Caused by: *java.lang.NoClassDefFoundError: 
org/drools/planner/core/solution/Solution*
         at java.lang.ClassLoader.defineClass1(Native Method) 
[rt.jar:1.7.0_07]
...

I suppose there are no  Optaplanner classes on guvnor classpath. Should 
they be? Or mayby guvnor do not need my problem definition(so guvnor 
wont need to use Solution interface )?

Is it generally good idea to try use guvnor to define scores?
