How should I recfactor if/else logic in HttpServlet

I am working on some coursework for a simple Java EE web application that records blog comments. On the add comment page there are two fields: name and comments

I am using a RequestDispatcher to pass control to an acknowledgement.jsp if the fields are not empty, and an error.jsp if one (or both) are empty passing a relevant message to the acknowledgement page.

This is the logic I have:

  RequestDispatcher disp;
  if (!name.isEmpty() && !comment.isEmpty())
  {
      CommentBean commentBean = new CommentBean();
      commentBean.setComment(comment);
      commentBean.setName(name);
      req.setAttribute("comment", commentBean);

      disp = req.getRequestDispatcher("acknowledgement.jsp");
      disp.forward(req, resp);

      return;
  } 
  else if (!name.isEmpty() && comment.isEmpty())
  {
      disp = req.getRequestDispatcher("error.jsp");
      statusMessage = "Comment field empty";
      req.setAttribute("status", statusMessage);
      disp.forward(req, resp);
  }
  else if (name.isEmpty() && !comment.isEmpty())
  {
      disp = req.getRequestDispatcher("error.jsp");
      statusMessage = "Name field empty";
      req.setAttribute("status", statusMessage);
      disp.forward(req, resp);
  }
  else
  {
      disp = req.getRequestDispatcher("error.jsp");
      statusMessage = "Name and comment fields empty";
      req.setAttribute("status", statusMessage);
      disp.forward(req, resp);
  }

The code does what I want but I can't help thinking this could be written a lot better but I am not sure how to go about it.

Edit: If this question should be written in another way please advise & I will edit straight away
