[omniORB] resolve() and _remote_non_existent()

[smitha smi]

Hi,


Below is the sequence of calls i make.

(1) o_ObjRef = rootContext->resolve(name);

This call is success as it is not throwing any exception.

(2)

try {

ServerReady_var l_readyObjRef = ServerReady::_narrow(o_ObjRef);

// Note: _is_nil call does not result in IPC

if (l_readyObjRef->_is_nil())

{

printf(" sink w/ server _narrow returned NIL");

break;

}

omniORB::setClientCallTimeout(

l_readyObjRef,15);

if(l_readyObjRef->_remote_non_existent())

{

printf("\n _remote_non_existent returned true\n");

}

}

catch (...)

{

printf("\n _remote_non_existent() threw an exception\n");

}

  Result of execution of this code is : "_remote_non_existent() threw an
exception"

Below are my concerns

(a) What is the difference between resolve() and _remote_non_existent() ?

(b) After successfully getting the object reference by calling resolve() ,
why show we make call to remote_non_existent() ?

(c) By searching i got to the below info

_CORBA_Boolean _remote_non_existent();

1.199 + // Contacts to object implementation to determine whether it exists.

1.200 + // It is possible that the implementation is a local servant of
course.

1.201 + // Returns 0 if the object exists, or 1 or throws OBJECT_NOT_EXIST
if

1.202 + // not. May throw other system exceptions.

1.203 + // This function is thread-safe.

If Object was not existing, then resolve() it self should have thrown
exception. but , it did not throw any exception Why?

Fact is that , Before this code gets executed.. Object is been registered
with Naming Service.

Please help me understand  , what is happening.

Thanks,

Smitha
