This is a snip of the original program, but this is the entire program:
namespace jme {
template <class T> class Data {
private:
     T data;
     int id;
public:
     Data();
     Data(T, const int);
     virtual ~Data();
     Data(const Data& other);
     Data& operator=(const Data& other);
     const int getId();
     const T& getData() {
         return data;
     }
};

template <class T>
jme::Data<T>::Data() {}

Members 'data' and 'id' have been left uninitialized here.

template <class T>
jme::Data<T>::Data(T _data, const int _id) {
this->data = _data;
this->id = _id;

See FAQ section 10 for recommendations on how to implement constructors.

}
template <class T>
jme::Data<T>::~Data() {}

If the destructor doesn't do anything, it's probably better to avoid
declaring and defining it at all.

template <class T>
jme::Data<T>::Data(const Data& other) {
     //copy ctor
}
template <class T>
jme::Data<T>&
jme::Data<T>::operator=(const Data& rhs) {
     //if (this == &rhs) return *this; // handle self assignment
     //assignment operator
     this->T = rhs.T;
     //this->id = rhs.id;
     return *this;
}
template <class T>
const int jme::Data<T>::getId() {
     return id;
}

int main(){
     jme::Data d;

When you try to instantiate the template, you must give it some real
arguments, like

jme::Data<int> d;

std::cout << "Hello world!" << std::endl;
return 0;
}
