As suspected.

This is your problem. As defined here, these operators belong to the
global namespace. But you want them to belong to the namespace jme:

namespace jme
{
  std::ostream &operator<<(std::ostream &os, Name const &obj)
  {
    return os << obj.getNameStr();
  }

  std::istream &operator>>(std::istream &is, Name &obj)
  {
    return is >> obj.str;
  }
}

and you should be fine.
