本文介绍了一种正确的CORBA IOR比较方法，避免使用简单的字符串匹配。通过将IOR转换为CORBA对象并利用_is_equivalent方法来判断两个IOR是否指向同一个对象。

Some different IOR string can be same org.omg.CORBA.Object object.

So the method to judge whether 2 IOR are same cannot use String.equal, instead:

    private boolean isSameIOR(String ior1, String ior2)
    {
        org.omg.CORBA.Object obj1 = null;
        org.omg.CORBA.Object obj2 = null;

        try {
            obj1 = orb.string_to_object(ior1);
            obj2 = orb.string_to_object(ior2);

            return obj1._is_equivalent(obj2);

        } catch (Exception e) {
            return false;
        }
    }

For example, following 2 IOR are different with String expression, but they are point to same object.

[IOR:000000000000003C49444C3A6F72672F63736170692F66772F66775F6163636573732F74727573745F616E645F73656375726974792F4970496E697469616C3A312E30000000000100000000000000780001020 00000000E3133352E3235322E3138312E3300BE5A00000021626A74657374332F7061726C6179504F412F4970496E697469616C5061726C6179313431000000020000000000000008000000004A414300000000010000001C00000000000100010000000105010001000101090000000105010001]
[IOR:000000000000003C49444C3A6F72672F63736170692F66772F66775F6163636573732F74727573745F616E645F73656375726974792F4970496E697469616C3A312E30000000000100000000000000780001025 00000000E3133352E3235322E3138312E3300BE5A00000021626A74657374332F7061726C6179504F412F4970496E697469616C5061726C6179313431000000020000000000000008000000004A414300000000010000001C00000000000100010000000105010001000101090000000105010001]

if use orb.rebind(naming, orb.string_to_object(ior)), and orb.resolve(naming) then

both IOR can get same result value.
