我有一個非常簡單的IDL文件：CORBA + JAVA +動態的客戶端 - 調用（）Request對象的方法失敗
module tests{
interface test {
boolean isEquals(in any num1, in any num2);
};
};
使用idlj後，我寫了整個應用程序（分爲服務器/公務員/客戶端），它工作正常。我現在唯一的問題是，當我嘗試重寫客戶端，因此它可能使用動態調用時，Requst對象的方法失敗。
客戶端的代碼：
ORB orb = ORB.init(args, null);
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
NamingContext ncRef = NamingContextHelper.narrow(objRef);
NameComponent nc = new NameComponent("testDynamic", "");
NameComponent[] path = {nc};
//Object objectRef = ncRef.resolve(path);
test objectRef = testHelper.narrow(ncRef.resolve(path));
(...)
Any any1 = orb.create_any();
Any any2 = orb.create_any();
NVList arglist = orb.create_list(2);
any1.insert_char('c');
any2.insert_char('d');
NamedValue nvArg = arglist.add_value("any1", any1, org.omg.CORBA.ARG_IN.value);
NamedValue nvArg2 = arglist.add_value("any2", any2, org.omg.CORBA.ARG_IN.value);
// create return value
Any result = orb.create_any();
// insert dummy value
result.insert_boolean(false);
NamedValue resultVal = orb.create_named_value("result", result,
org.omg.CORBA.ARG_OUT.value);
// create request
Request req = objectRef._create_request(null, "isEquals", arglist, resultVal);
req.invoke();
運行客戶端導致的錯誤，與req.invoke() beeing的犯罪嫌疑人：
（在錯誤日誌的最後一行是at server.TestClient.main(TestClient.java:75)，這是req.invoke()方法）

我可以要求一點幫助嗎？ 謝謝。
Corba！哇。所以你是唯一。 – MeBigFatGuy 2011-04-11 02:26:37
@MeBigFatGuy - 請告訴我的教授:) – zeroDivisible 2011-04-11 03:06:48
