Template problem

Anybody care to explain why the below code doesn't work?

TIA!

, Espen
#include <iostream>
class TypeTXT {
public:
TypeTXT( void ) { std::cout << " TypeTXT" << std::endl; }
~TypeTXT( void ) { std::cout << "~TypeTXT" << std::endl; }
};
class TypeBMP {
public:
TypeBMP( void ) { std::cout << " TypeBMP" << std::endl; }
~TypeBMP( void ) { std::cout << "~TypeBMP" << std::endl; }
};
template< class Object > DataObject {
public:
DataObject( void ) { std::cout << " DataObject" << std::endl; }
~DataObject( void ) { std::cout << "~DataObject" << std::endl; }
};
int main( void ) {
DataObject< TypeTXT > ObjectTXT;
DataObject< TypeBMP > ObjectBMP;
return 0;
}
