ILOG Jrules规则集EJB怎么调用

我的代码如下：
public class JruleInvokerTest { public static void main(String[] args) {
try {
IlrStatelessSession stateLessSession;
IlrEJB3SessionFactory factory = new IlrEJB3SessionFactory();
factory.setStatelessRemoteJndiName("ilog.rules.res.session.impl.ejb3.IlrStatelessSessionRemote");
factory.setRemote(true);
Hashtable<String, Object> env = new Hashtable<String, Object>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "corbaloc:iiop:127.0.0.1:2809");
InitialContext ic = new InitialContext(env);
Object lookupResult = ic.lookup("ilog.rules.res.session.impl.ejb3.IlrStatelessSessionRemote");
//Object lookupResult = ic.lookup("ejb/IlrStatelessRuleSessionEJB");
stateLessSession = (IlrStatelessSession) PortableRemoteObject.narrow(lookupResult, IlrStatelessSession.class);

IlrSessionResponse sessionResponse = null;
IlrSessionRequest sessionRequest = null;
sessionRequest = factory.createRequest();
sessionRequest.setRulesetPath(IlrPath.parsePath("/orderDecisionruleapp/OrderDecisionRules")); OrderDecision od = new OrderDecision("IBM", 100.00, 20.00); sessionRequest.setInputParameter("orderDecision", od);
sessionResponse = stateLessSession.execute(sessionRequest);
Map<String, Object> map = sessionResponse.getOutputParameters(); Object obj = map.get("orderDecision");
if (obj != null) {
OrderDecision orderDecision = (OrderDecision) obj;
Boolean canContinue = orderDecision.getCanContinue();
if (canContinue != false) {
System.out.println("SUCCESS");
} else {
System.out.println("FAILD");
}
}
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException("Ilog Jrules Invoke Exception："
+ e.getMessage(), e);
}
}}报的错误：
