And now I can load drl by the below way. But I dont know how to dynamically load java classes by String type. For example: I have a drl which is  including class Person, so the Person must be existed in my project. However my service is running, I can not restart the serbice, and I have Person class in my database as String type. How can I load the String Person to kiebase? please help me, thank you very much! {code:java} public static void loadRulesFromStr(InternalKnowledgeBase kBase, List<String> drls) { KnowledgeBuilderConfiguration kbc = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(); KnowledgeBuilder kBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbc); for (String drl : drls) { kBuilder.add(ResourceFactory.newByteArrayResource(drl.getBytes()), ResourceType.DRL); } if (kBuilder.hasErrors()) { System.out.println(kBuilder.getErrors().toString()); } kBase.addPackages(kBuilder.getKnowledgePackages()); } {code}
