Re: [rules-users] Rules compilation error with OSGi integration (6.1.0.Beta3)
Hello. Although without much conviction, I've tried the Bundle-RequiredExecutionEnvironment: J2SE-1.7, but it doesn't change the compilation level of the rules... As I said in a previous answer, I don't know exactly how to do it, but I think the solution may be in the way that Drools takes the classloader passed by the application to have access to specific classes like the usually imported beans used in the rules. Indeed, perhaps that instead of using directly this classloader, for its tasks, among of them the rules compilation, it should be possible to use some kind of enriched classloader that carries all the Drools needed packages, and delegates application classes resolution to the application's one. What do you think of that ?

If you look to my example posted previously there are no issues. Can you make a test using just Apache Karaf 2.3.x with Drools 6.1.0.Beta3 and tell me what happen. Which JDK do you sue ?

Hello. I could try to test on ServiceMix 5 that embeds Karaf 2.3.4, but for my concrete project, the customer current platform uses a ServiceMix 4.5.3 which is not really possible to change today while many other modules are already deployed.

[rules-users] Using KieScanner in drools6
Hi Team, I go through with the release doc http://docs.jboss.org/drools/release/6.0.0.Final/drools-docs/html_single/ and found that 2.1.6. KieScanner The KieScanner is a maven-oriented replacement of the KnowledgeAgent present in Drools 5. using knowledgwAgent I have linked through changeset.xml by below code in drools 5.4 KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent(MyAgent1,kbase, kconf); ResourceFactory.getResourceChangeNotifierService().start(); ResourceFactory.getResourceChangeScannerService().start(); kagent.applyChangeSet(ResourceFactory.newUrlResource(http://localhost:8380/drools-guvnor/ChangeSet.xml;)); kbase = kagent.getKnowledgeBase(); How I can achieve this using drools 6 to interact with my java code to drools workbench. or which drools 6 need to download to interact with java code.

Re: [rules-users] Using KieScanner in drools6
Hi Mark, Thanks for suggestions.I will go through with above link I go through with document it uses maven, I do not have any knowledge on maven, Do I need to learn maven to develop project in drools 6 ? I developed using changeset.xml to link java and drools, And drools-guvnor.war, and designer.war in drools 5.4 version. If I develop maven project how to link maven and workbench - I felt confusing in this, Does following code helps KieServices kieServices = KieServices.Factory.get(); ReleaseId releaseId = kieServices.newReleaseId( *org.acme, myartifact, 1.0-SNAPSHOT* ); KieContainer kContainer = kieServices.newKieContainer( releaseId ); KieScanner kScanner = kieServices.newKieScanner( kContainer ); // Start the KieScanner polling the Maven repository every 10 seconds kScanner.start( 1L ) 2. I practiced some workbench tutorial.. and its almost different from drools 5.4, Is there any possible of integrating drools workbench and java code, or else I need to use any other drools war to develop application thanks for your patience .

Re: [rules-users] XML and the Guided Decision Tables
There is no schema for a GDST; it's simply an XStream dump of the POJO model behind the editor. We support conversion of XLS decision tables to GDST as from 5.4 (I think; it's definitely in 5.5 and 6.0). If either (a) you're not using XLS decision tables or (b) you want them converted outside of the workbench you could always have a look at the code that handles conversion and write something yourself (droolsjbpm/drools-wb/drools-wb-screens/guided-dtable or a path to that effect).
