Re: [rules-users] drl to pkg

This is what you might do: KnowledgeBase kBase = KnowledgeBaseFactory.newKnowledgeBase(); KnowledgeBuilder kBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kBuilder.add( ResourceFactory.newFileResource( "Movie.drl" ), ResourceType.DRL ); if( kBuilder.hasErrors() ){ for( KnowledgeBuilderError err: kBuilder.getErrors() ){ System.out.println( err.toString() ); } throw new IllegalStateException( "DRL errors" ); } OutputStream os = new FileOutputStream( "Movie.pkg" ); ObjectOutputStream oos = new ObjectOutputStream( os ); oos.writeObject( kBuilder.getKnowledgePackages() ); // And now, from the file containing the binary knowlewdge packages: InputStream is = new FileInputStream( "Movie.pkg" ); ObjectInputStream ois = new ObjectInputStream( is ); @SuppressWarnings("unchecked") Collection<KnowledgePackage> kpkgs = (Collection<KnowledgePackage>) ois.readObject(); ois.close(); kBase.addKnowledgePackages( kpkgs ); -W 2009/5/2 Perumaal Krishnaraj <perumaal.k(a)gmail.com&gt;
