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
