CORBA IDL "pragma ID" not solving problem

Question

Similar to "CORBA Bug?", I get the stacktrace that is listed at the end of this note. I have put "pragma ID..." for typedefs, structs and interfaces in my idl file. I did nothing else to the code. The same errors were generated, so I assume the "pragma ID..." had no effect.
This program connects to a Cloudscape DB on the server, and works very well with servants that have only "string" types. It produces errors with strings that have user-defined or boolean return types.
I appreciate any help in this matter.

Answer 1

I had this problem myself and I finally managed to crack it ...
Let's take an example IDL for reference
    typedef string<100> Name;
    struct PersonStruct {
        string  age;
        Name    name;
    typedef sequence<PersonStruct> PersonSeq;
    interface PersonHandling {
        long getPersons(in string personId, in Name name, out PersonSeq persons);
    };The method getPerson returns an array of PersonStructs.
The most likely place where the error 202 is thrown is in the implementation class
     public int getPersons(String personId, String name, PersonSeqHolder persons) {
            PersonStruct a = new PersonStruct();
            a.age = "28";
            a.name = "John Smith";
            persons = new PersonSeqHolder();    //this line is the cause of error 202
            persons.value = new PersonStruct[]{a};                                         
            return 0;          
        }The return PersonSeqHolder object should not be reinitialised. We must use the object given in the input params as is ..
i.e. persons = new PersonSeqHolder();//should be removed Remove this line and simply set the value
     persons.value = new PersonStruct[]{a};
