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?

Hello,
How Optaplanner and Guvnor should be integrated? I am using Drools
5.5.0.Final. I have configuration with spring so I have access to
KnowledgeBase.
I found in documentation:
5.3.4.2.2. A RuleBase (possibly defined by Guvnor)
solverFactory.getSolverConfig().getScoreDirectorFactoryConfig.setRuleBase(ruleBase);
How I can get rule base? (If it is correct way do integrate with guvnor)
yes, it's the correct way for optaplanner 5.5.x with drools 5.5.x:
IIRC, the guvnor docs explains how you can get a KnowledgeBase (~
drools 5 api), which you can transform into a RuleBase (~ drools 4 api
which is still available in 5.5.x) like this:
|((InternalKnowledgeBase) myKnowledgeBase).getRuleBase()|
See
http://stackoverflow.com/questions/11017613/live-rule-creation-in-drools-planner
IIRC, KnowledgeAgent connects to guvnor and builds a KnowledgeBase.
That being said, for optaplanner 6.0.x with drools 6.0.x,
everything is standardized on KieBase (~ drools 6 api) (which is like
the KnowledgeBase in the 5 api).
We recently released 6.0.0.Beta3 (drools, guvnor and optaplanner
release together).
So there's
solverFactory.getSolverConfig().getScoreDirectorFactoryConfig.setKieBase(kieBase);
The optaplanner and drools stuff is pretty stable, even if it's called
Beta3 (CR1 is coming soon),
but I have no idea about the state of guvnor's KieBase support.
Thanks,
