Re: [rules-users] Drools in jBPM

I have problem in using drools in simple jBPM application. Every thing works fine while it is runs under JUNIT but when I export it to jBPM i got exception org.jboss.resteasy.spi.UnhandledException: org.drools.RuntimeDroolsException: Unable to resolve class 'myclass.jbpm.vrk.Claim' org.jboss.resteasy.core.SynchronousDispatcher.handleApplicationException(SynchronousDispatcher.java:319) org.jboss.resteasy.core.SynchronousDispatcher.handleException(SynchronousDispatcher.java:230) org.jboss.resteasy.core.SynchronousDispatcher.handleInvokerException(SynchronousDispatcher.java:206) org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:360) org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:173) org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:93) org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:68) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.jboss.bpm.console.server.util.GWTJsonFilter.doFilter(GWTJsonFilter.java:59) root cause org.drools.RuntimeDroolsException: Unable to resolve class 'myclass.jbpm.vrk.Claim' org.drools.base.ClassFieldAccessorCache.getClass(ClassFieldAccessorCache.java:269) org.drools.base.ClassFieldAccessorCache.getReadAcessor(ClassFieldAccessorCache.java:241) org.drools.base.ClassFieldAccessorStore.wire(ClassFieldAccessorStore.java:379) org.drools.base.ClassFieldAccessorStore.merge(ClassFieldAccessorStore.java:270) org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:466) org.drools.reteoo.ReteooRuleBase.addPackages(ReteooRuleBase.java:379) org.drools.impl.KnowledgeBaseImpl.addKnowledgePackages(KnowledgeBaseImpl.java:121) myclass.jbpm.drools.DroolsRulesManager.runDrlRule(Unknown Source) My drl is very simple: import myclass.jbpm.vrk.Claim; rule "Rule 01" when $claim : Claim( $date : date, $elements : elements, $simpleClaim : simpleClaim ) eval( $elements<= 10 ) then $claim.setSimpleClaim( true ); System.out.println("It's a simple claim!: " + $date + ", elements: " + $elements + ", simple: " + $simpleClaim); end The only way to solve it is to write new ClassLoader and pass it to KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(null, myNewClassLoader); , or this error is caused by something else?
