Hi, This boiler plate code demonstrates a rather, I suspect large, problem:- @Test public void testPackageAttributesFromDRL() { KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( new ClassPathResource( "org/drools/example.drl" ), ResourceType.DRL ); //<--- Error KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); } throws:- java.lang.NullPointerException at org.drools.compiler.PackageBuilder.generateDeclaredBean(PackageBuilder.java:1433) at org.drools.compiler.PackageBuilder.processTypeDeclarations(PackageBuilder.java:1272) at org.drools.compiler.PackageBuilder.mergePackage(PackageBuilder.java:895) at org.drools.compiler.PackageBuilder.newPackage(PackageBuilder.java:883) at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:601) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:297) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:473) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) at org.drools.BinaryPackage.testPackageAttributesFromDRL(BinaryPackage.java:35) In org.drools.compiler.PackageBuilder.generateDeclaredBean the call to the following returns null. JavaDialectRuntimeData dialect = (JavaDialectRuntimeData) pkgRegistry.getDialectRuntimeRegistry().getDialectData( "java" ); DRL is:- package example declare Person age: Integer name: String end rule "Row 1 dtable" salience 1 dialect "mvel" when $p : Person( name == "Bill" , age != "30" ) then $p.setAge( 12345 ); end It worked OK yesterday. Any takers? With kind regards, Mike

Neither can I, in sync with master from the blessed one. -W On 28 April 2011 15:11, Michael Anstis <michael.anstis(a)gmail.com&gt; wrote: > Hmmm....
