Hi Esteban, I need to know whether we can* convert XML file to normal drl file* in Drools 5.3.0 Final Guvnor.If it is possible how?? PackageBuilderConfiguration conf = new PackageBuilderConfiguration(); XmlPackageReader reader = new XmlPackageReader(conf.getSemanticModules()); DrlDumper dumper = new DrlDumper(); FileReader filereader = new FileReader("test_ParseGlobal.xml"); PackageDescr descr = reader.read(filereader); String test = dumper.dump(descr); System.out.println(test); FileWriter writer = new FileWriter(new File("test_ParseGlobal.drl")); writer.write(dumper.dump(descr)); writer.flush(); writer.close(); This is my code to convert it..Is it correct?..My XML file test_ParseGlobal.xml contains the rule content what is present in the above link.But the above code compilation fails and returning Exception in thread "main" java.lang.NullPointerException at org.drools.xml.ExtensibleXmlParser.resolveSchema(ExtensibleXmlParser.java:696) at org.drools.xml.ExtensibleXmlParser.resolveEntity(ExtensibleXmlParser.java:622) at org.apache.xerces.util.EntityResolverWrapper.resolveEntity(Unknown Source) at org.apache.xerces.impl.XMLEntityManager.resolveEntity(Unknown Source) -- View this message in context: http://drools.46999.n3.nabble.com/XML-Rule-Language-Please-help-tp3587815...

The ony requirement is that I'm practicing the Drools Expert guide 5.3 concepts.So,In that there is specification that we can convert XML files to DRL vice-versa using some classes(as mentioned above).But,I'm unable to do.. Can't we convert XML to DRL as specified in the Drools expert guide.It's not heavy requirement for my application but I need to know as I'm surfing drools more... -- View this message in context: http://drools.46999.n3.nabble.com/XML-Rule-Language-Please-help-tp3587815...

Maybe some of the core devs could shade some light here, but I think the documentation is wrong when it states "All the features are available with XML that are available to DRL.". I think my advise would be: if you don't need to use xml for any special reason, then don't use it. Use DRL format instead.

Hi Sir, I have another Problem Please try to give some suggestion. how can i provide my Kbase object loaded with all packages is at one context , and can i make it available to other context applications or webservices Ex:My actual scenario is :I created all my rules and loaded my application as KnowledgeBuilder kbuilder1 = KnowledgeBuilderFactory.newKnowledgeBuilder(); KnowledgeBase kbase1 = readKnowledgeBase(); // Like this i added some 50 packages and build single kbase haveing 15000 rules kbuilder1.add(ResourceFactory.newUrlResource(" http://localhost:8082/guvnor-5.3.0.Final-jboss-as-5.1/org.drools.guvnor.G... "),ResourceType.PKG); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder1.getKnowledgePackages()); This code i made it as .sar file,so it loads automatically when server start up without user control -- which is loaded is in one context, as per my understanding kbase object is present in that context. Now can I make that kbase object available to web service which is present in some other context(some other application) , so that web service can make use of kbase which is already available (Instead of creating and loading new kbase).. So far,you suggested so many solutions.Hope you will help me to get out of this problem.
