Question

我在调用方法(BAD_PARAM) Null parameter时收到opt2()错误。我的另一种方法opt1()运行正常。以下是他们的定义：

void call1()
{
    StringHolder text2 = new StringHolder("bolek");
    StringHolder text3 = new StringHolder("a");
    S1 s1 = new S1();
    s1.a = 77;
    s1.b = 'r';

    i1.op1(123);

    String res = i1.op2("myString", text2, text3, s1);

    System.out.println(res);
}

@Override
public short op1(int abc) {
    // TODO Auto-generated method stub
    System.out.println("OP1 " + abc);
    return 0;
}

@Override
public String op2(String text, StringHolder text2, StringHolder text3,
        S1 struct1) {
    return text+" "+text2+" "+text3+" "+struct1.a+" "+struct1.b;
}

S1是一个包含int a和char b的结构。

我得到以下堆栈跟踪：

我该如何解决这个问题？

JAVA CORBA（BAD_PARAM）空参数
