[omniORB] Newbie omniORB problem; unknown system exception?

[Stephen Hansen]

Hello all.
    
I'm trying to see if omniORB will work in our project, and have run into
a bit of a snag. I'm using omniORB and omniORBpy to talk back and forth
between a couple different applications. For right now i have something
very simple in place:
 
    module FalconLayout {
        interface LayoutAgent {
            unsigned short GetDocumentCount();
        };
    };
 
That's all :) My C++ code, in Visual C++ 7.1, which is mostly just from
the boilerplate example produced by omniidl:
 
----------------------------------------------------------

#include <iostream>
#include <fstream>
#include "FalconLayout.h"

using namespace std;
ofstream err("c:\\corba.error");

class FalconLayout_LayoutAgent_i: public POA_FalconLayout::LayoutAgent,
	public PortableServer::RefCountServantBase {
	private:
	public:

		FalconLayout_LayoutAgent_i();
		virtual ~FalconLayout_LayoutAgent_i();

		CORBA::UShort GetDocumentCount();

};

FalconLayout_LayoutAgent_i::FalconLayout_LayoutAgent_i(){}

FalconLayout_LayoutAgent_i::~FalconLayout_LayoutAgent_i(){}

CORBA::UShort FalconLayout_LayoutAgent_i::GetDocumentCount(){
	return CORBA::UShort(33);
}

CORBA::ORB_var globalOrb;

void runOrb() {
	try {
		char* emptylist = {"editpag"};
		int count = 0;
		globalOrb = CORBA::ORB_init(count, &emptylist);

		CORBA::ORB_var orb = globalOrb;

		CORBA::Object_var obj =
orb->resolve_initial_references("RootPOA");
		PortableServer::POA_var poa =
PortableServer::POA::_narrow(obj);

		FalconLayout_LayoutAgent_i* myFalconLayout_LayoutAgent_i
= new FalconLayout_LayoutAgent_i();
		PortableServer::ObjectId_var
myFalconLayout_LayoutAgent_iid =
poa->activate_object(myFalconLayout_LayoutAgent_i);

		{
			CORBA::Object_var ref =
myFalconLayout_LayoutAgent_i->_this();
			CORBA::String_var
sior(orb->object_to_string(ref));
			cout << "IDL object FalconLayout::LayoutAgent
IOR = '" << (char*)sior << "'" << endl;\
			ofstream outf("c:\\ref.ref");
			outf << (char*)sior;
		}

		PortableServer::POAManager_var pman =
poa->the_POAManager();
		pman->activate();
	}
	catch(CORBA::SystemException&) {
		err << "Caught CORBA::SystemException." << endl;
	}
	catch(CORBA::Exception&) {
		err << "Caught CORBA::Exception." << endl;
	}
	catch(omniORB::fatalException& fe) {
		err << "Caught omniORB::fatalException:" << endl;
		err << " file: " << fe.file() << endl;
		err << " line: " << fe.line() << endl;
		err << " mesg: " << fe.errmsg() << endl;
	}
	catch(...) {
		err << "Caught unknown exception." << endl;
	}

};

void doWork() {
	try {

		CORBA::ORB_var orb = globalOrb;
		if(orb->work_pending()) {
			orb->perform_work();
		}
	}
	catch(CORBA::SystemException&) {
		err << "Caught CORBA::SystemException." << endl;
	}
	catch(CORBA::Exception&) {
		err << "Caught CORBA::Exception." << endl;
	}
	catch(omniORB::fatalException& fe) {
		err << "Caught omniORB::fatalException:" << endl;
		err << " file: " << fe.file() << endl;
		err << " line: " << fe.line() << endl;
		err << " mesg: " << fe.errmsg() << endl;
	}
	catch(...) {
		err << "Caught unknown exception." << endl;
	}
}

void stopOrb() {
	try {
		CORBA::ORB_var orb = globalOrb;
		err.close();
		orb->destroy();
	}
	catch(CORBA::SystemException&) {
		err << "Caught CORBA::SystemException." << endl;
	}
	catch(CORBA::Exception&) {
		err << "Caught CORBA::Exception." << endl;
	}
	catch(omniORB::fatalException& fe) {
		err << "Caught omniORB::fatalException:" << endl;
		err << " file: " << fe.file() << endl;
		err << " line: " << fe.line() << endl;
		err << " mesg: " << fe.errmsg() << endl;
	}
	catch(...) {
		err << "Caught unknown exception." << endl;
	}
}

----------------------------------------------------------

The application is calling runOrb, then doWork periodically, and stopOrb
at end. The corba.error file is being steadily filled with
SystemExceptions. I don't know how to dignose what's causing that :)

Help?

Thanks!
