Hi Duncan!

The idl, locator and servant implementation source is also included at

// 1. IDL
module Quoter
{
  interface Stock_Factory
  {
    double get_stock (in string stock_symbol);
  };
};

// 2. Locator
//preinvoke
{
  cout << "Quoter_Stock_Factory_i::preinvoke()" << operation << endl;
  return new Quoter_Stock_Factory_i;
}
//postinvoke
{
  cout << "Quoter_Stock_Factory_i::postinvoke()" << endl;
  the_servant->_remove_ref();
}

// 3. servant implementation
class Quoter_Stock_Factory_i : public POA_Quoter::Stock_Factory,
		    public PortableServer::RefCountServantBase {
public:
  virtual ~Quoter_Stock_Factory_i()
	{ cout << "Quoter_Stock_Factory_i::~Quoter_Stock_Factory_i()" <<
endl; }

  CORBA::Double get_stock (const char *symbol)
  {
	cout << "Inside the get stock function" << endl;
	return 7.0;
  }
};

// 4. Any more source needed???

Something bad has happened if you get that error, but it's difficult
to see what. Try running your program with command line arguments of
-ORBtraceLevel 25 -ORBtraceInvocations, and see if the output reveals
more of what's going wrong.

Cheers,

Duncan.
