Gosh, you're so close.

If you change this method:
function fnClickAddEmail() {
      var email = $("input#email").val();
      $.post(
          "validateEmail.do",
          {sendValue: email},
          function(returnValue){   //Does this function called even my
email is invalid? Am I getting email.jsp page in "returnValue"?
              addToTable(returnValue);
          },
          "text"
      );
}

To this:
function fnClickAddEmail() {
      var email = $("input#email").val();
      $.post(
          "validateEmail.do",
          {sendValue: email},
          function(returnValue){
                if (returnValue == "") {
                        // Show Error Message
                } else {
                        addToTable(returnValue);
                }
          },
          "text"
      );
}

This should get your implementation working for you.  You're still not
utilizing JSON, but with the modified method it should work for you.
