[rules-users] OptaPlanner Guvnor integration

[Bartek]

I get it to work. Four steps where needed:
1. Adding

  private KnowledgeBase *kBase*;//injected with Spring
....
         // Build the Solver
         SolverFactory solverFactory = new 
XmlSolverFactory("/planner/solverConfig.xml");
         RuleBase ruleBase = ((InternalKnowledgeBase) 
*kBase*).getRuleBase();
solverFactory.getSolverConfig().getScoreDirectorFactoryConfig().setRuleBase(ruleBase);

to my code to link Guvnor and solverFactory.

And spring integration with Drools:

    <drools:kbase id="knowledgeBase"/>
     <drools:kagent kbase="knowledgeBase" id="kagent" new-instance="false">
         <drools:resources>
             <drools:resource type="PKG"
                              source="${drools.url}"
                              basic-authentication="enabled"
                              username="admin"
                              password="admin"/>
         </drools:resources>
     </drools:kagent>

  <bean id="planner" class="...">
         <property name="*kBase*" ref="knowledgeBase"/>
     </bean>

2. Importing drools-planner-core-5.5.0.Final.jar in Guvnor (Upload POJO 
Model jar)
3. Adding global in Guvnor:
   global 
org.drools.planner.core.score.buildin.hardandsoft.HardAndSoftScoreHolder 
scoreHolder
4. Adding drools-planner-core-5.5.0.Final.jar to WEB-INF/lib in Guvnor 
instalation directory. Without that I still get NoClassDefFoundError 
while importing my domain in Guvnor.

Best regards
