[omniORB] TypeCode Any problems

Hello,

I have a following problem with typeCode and Any. It will be a little bit
long but it is complicated. I am using the latest omniorb, compiled from
source

I have a self made idl file. I do no use omniidl for cc creation, everything
is done by hand, and must be done by hand.

Idl:

  struct a

  {

    string n;

    any v;

    long f;

    short l;

  };



  typedef sequence<a> alist;

  typedef sequence<alist> alistlist;



  interface _interface

  {

    alist exec (in string s,  in alist arg )

}

First problem, that the a.v is type any, and the software is using this
opportunity, and putting a alist in there from a, what contains a alistlist.



CORBA::Request_ptr req = obj->_request("exec");

req->add_in_arg("arguments") = the string

req->add_in_arg("arguments") = the arg



I create a TypeCode for the “a”

CORBA::StructMemberSeq tc;

tc.length(4);

tc [0].name = CORBA::string_dup("n");

tc [0].type = CORBA::TypeCode::_duplicate(CORBA::_tc_string);

tcs[1].name = CORBA::string_dup("v");

tc[1].type = CORBA::TypeCode::_duplicate(CORBA::_tc_any);

tc [2].name = CORBA::string_dup("f");

tc [2].type = CORBA::TypeCode::_duplicate(CORBA::_tc_long);

tc [3].name = CORBA::string_dup("l");

tc [3].type = CORBA::TypeCode::_duplicate(CORBA::_tc_short);

CORBA::TypeCode_var tc_var = orb->create_struct_tc("IDL:c/*l*/*c*/*s*/a:1.0"
,"a", tc);



CORBA::Object_ptr dafo = orb->resolve_initial_references("__");

DynamicAny::DynAnyFactory_var daf =
DynamicAny::DynAnyFactory::_narrow(dafo);

DynamicAny::DynAny_var dv = daf->create_dyn_any_from_type_code(tc_var);

The first string insertion is easy

dv->insert_string(_par.name());

dv->next();

//if the list type code creation is needed then

CORBA::TypeCode_var tc_list= orb->create_sequence_tc(0, tc_var );

tc_list = orb->create_alias_tc("IDL:c/*l*/*c*/*s*/alist:1.0","alist"
,tc_list);

CORBA::TypeCode_var tc_listlist= orb->create_sequence_tc(0, tc_list );

tc_listlist = orb->create_alias_tc("IDL:c/*l*/*c*/*s*/alistlist:1.0",
"alistlist",tc_listlist);



//after that dynamic arrays are created, the dynamic listlist is the same

DynamicAny::DynAny_var dv = daf->create_dyn_any_from_type_code(tc_list);

DynamicAny::DynSequence_var daSeq=DynamicAny::DynSequence::_narrow(dv);



DynamicAny::DynAny_var dv = daf->create_dyn_any_from_type_code(tc_listlist);

DynamicAny::DynSequence_var daSeq=DynamicAny::DynSequence::_narrow(dv);





//I wont list here the whole code, from these sequence an any type _any is
created, an that _any is put to

dv->insert_any(_any);

dv->next();

and the dv is filled with other values.



Finally the dv->to_any() is called and this is handed to the

req->add_in_arg("arguments") =



The problem is that in the “request” not all the type code is listed only
for the tc_list one.

To my opinion and this way is excepted from the “server” side, all the

tc_listlist, tc_list and tc description/id should be visible in the logs,
and the server is answering that it cannot interpret the values.

My question is that how should I enforce that the description/id content to
be part of the request? What am I using wrong?

Thanks in advance
