Naming Service help

Anonymous — Wed, 11 May 2005 15:37:48 -0000

i have existing TAO CORBA server/client applications in
C++ and want to port the server to C# using
Remoting.Corba. The server binds it's CORBA object
with the Nameing Service with 2 name component ids.
for example

CosNaming::Name_var context = new
CosNaming::Name(0);

context->length(2);
context[0].id = "root";
context[0].kind = "";
context[1].id = "interface1";
context[1].kind = "";

when i attempt to create 2 NameComponents using
Remoting.Corba i get an exception when binding.

NameComponent[] name = new NameComponent[2];
name[0] = new NameComponent("root", "");
name[1] = new NameComponent("interface1", "");
nameService.rebind(name, Ior.Parse(ior));

any help?

great project, BTW :D

Exception's properties not working.

Anonymous — Tue, 06 Jan 2004 15:54:07 -0000

I have a full working project with an IDL I imported using
IDL2CS, and everything works fine, except for the fact
that none of the exception's have its properties filled.
The company that made the IDL just swears that this
properties are being filled on the server-side, but I can't
get its values. Do you have any idea what could be
happening? Thanks in advance.

Connection closes after a while (Socket Closes down)

I get the Following Error after a while :

/////////////// START ERROR //////////////////

Could this be because the messages are sent too fast /
ie. the Socket can't handle the amount of messages
coming through and thus 'forcibly closes ' ?

Any Help would be appreciated.

1.3.1 union type mapping

Anonymous — Fri, 06 Jun 2003 22:51:56 -0000

Apperently v1.3.1 supports Unions, but I don't
understand how to use them. As an example, I have
been trying to understand the CorbaTestServer.idl
mapping. I have the following union in my IDL that
represents a tree object, how do write the C# mapping
for it?

enum ValueTypes {LONGLONG_TYPE, ULONGLONG_TYPE,
FLOAT_TYPE, DOUBLE_TYPE, STRING_TYPE,
DATE_TYPE, DATETIME_TYPE, LONGSEQ_TYPE,
ULONGSEQ_TYPE, ONGLONGSEQ_TYPE,
ULONGLONGSEQ_TYPE, FLOATSEQ_TYPE,
DOUBLESEQ_TYPE, STRINGSEQ_TYPE, DATESEQ_TYPE,
DATETIMESEQ_TYPE, VALUESEQ_TYPE, NULL_TYPE
};

typedef sequence<long long> LonglongSequence;
typedef sequence<unsigned long long>
UlonglongSequence;
typedef sequence<float> FloatSequence;
typedef sequence<double> DoubleSequence;
typedef sequence<string> StringSequence;
typedef sequence<Date> DateSequence;
typedef sequence<DateTime> DateTimeSequence;

union Value switch(ValueTypes) {
case LONGLONG_TYPE:
long long longlongval;
case ULONGLONG_TYPE:
unsigned long long ulonglongval;
case FLOAT_TYPE:
float floatval;
case DOUBLE_TYPE:
double doubleval;
case STRING_TYPE:
string stringval;
case DATE_TYPE:
Date dateval;
case DATETIME_TYPE:
DateTime datetimeval;
case LONGLONGSEQ_TYPE:
LonglongSequence longlongseqval;
case ULONGLONGSEQ_TYPE:
UlonglongSequence ulonglongseqval;
case FLOATSEQ_TYPE:
FloatSequence floatseqval;
case DOUBLESEQ_TYPE:
DoubleSequence doubleseqval;
case STRINGSEQ_TYPE:
StringSequence stringseqval;
case DATESEQ_TYPE:
DateSequence dateseqval;
case DATETIMESEQ_TYPE:
DateTimeSequence datetimeseqval;
case VALUESEQ_TYPE:
sequence<Value> valueseqval;
};
struct Node {
Value val;
sequence<Node> children;
};

thanks in advance. If there is a more appropriate place
for me to post messages like this let me know.

how would you convert this IDL to a proxy?

// Bank.idl

module Bank {
interface Account {
float balance();
};
interface AccountManager {
Account open(in string name);
};
};
