swapnil thanx for the reply,
this is my modified code
try{
System.out.println("Initializing Fact....");
URL[] urls = new URL[]{ new URL("file://"+path) };
ClassLoader loader = new URLClassLoader(urls);
Class clazz = loader.loadClass("test.Message");
//Class.forName("test.Message", false, ucl);
Object factObj = clazz.newInstance();
String ruleFile = "test/Sample.drl";
Method method = clazz.getMethod("setMessage", new
Class[]{String.class});
Method method1 = clazz.getMethod("getMessage");
//System.out.println("facts loaded\n");
method.invoke(factObj, new Object[]{"Hello"});
System.out.println("initializing packageBuilder");
PackageBuilderConfiguration config = new
PackageBuilderConfiguration();
config.setClassLoader(loader);
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder(config);
System.out.println("finding Rule");
kbuilder.add(ResourceFactory.newClassPathResource("test/Sample.drl"),ResourceType.DRL);
if (kbuilder.hasErrors())
throw new RuntimeException("Unable to compile rules. " +
kbuilder.getErrors().toString());
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(new
RuleBaseConfiguration(loader));
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
StatelessKnowledgeSession session =
kbase.newStatelessKnowledgeSession();
System.out.println("running rule....... \n");
session.execute(factObj);
System.out.println("\nend...\n");
System.out.println(method1.invoke(factObj).toString());
}
catch (Throwable t) {
t.printStackTrace();
}
