CORBA::String_var -> I can't assign any value to class field of this type

Question

I have a simple class:

class MyExample : public POA_Example
{
   CORBA::String_var field;

   public:
             char* getField();
             void setField(const char* f);
};

char* MyExample::getField()
{
   return CORBA::string_dup(this->field.out());
}

void MyExample::setField(const char* f)
{
   this->field = CORBA::string_dup(f);
}

And main app:

#include "MyExample.h"
#include <iostream>
using std::cout;

int main()
{
  MyExample e;
  e.setField("Hello");
  cout << e.getField() << "\n";
  return 0;
}

I use omniORB and the code I gave above doesn't show anything ... Whats the problem here?

Answer 1

If you are using omniORB, you may have to at least call orb_init() before string operations will work right. The code you have seems fine otherwise.

(Although you do not have to call string_dup() in the setField() function, as the String_var class will automatically do that when you assign it a const char*.)

(And you are leaking memory by calling e.getField() in your cout. But that shouldn't prevent you from seeing something.)
