CORBA&x2B；JAVA+；请求对象的动态客户端调用（）方法失败

我有一个非常简单的IDL文件：

module tests{

  interface test {
    boolean isEquals(in any num1, in any num2);
  };
};

在使用了

idlj

之后，我已经编写了整个应用程序（分为服务器/服务/客户端），并且运行正常。我现在唯一的问题是，当我试图重写客户机以便它可以使用动态调用时，Requst对象的

ivoke（）

方法失败

客户端的代码：

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();

运行客户端会导致一个错误，

req.invoke（）

是可疑的：

（错误日志中的最后一行是server.TestClient.main（TestClient.java:75），这是

req.invoke（）

方法）

我可以请求一些帮助吗？

谢谢。

可能是参数类型的问题，与封送处理有关。字符串必须使用CORBA:：string_alloc（或java等效工具）进行分配。

CORBA！哇！所以你就是那个。@MeBigFatGuy-请告诉我的教授：）科尔巴！哇！所以你就是那个。@MeBigFatGuy-请告诉我的教授：）
