AJAX is an acronym for Asynchronous JavaScript And XML. It provides an ability to communicate with the server asynchronously.

To explain that in simple terms, you can send a request to server and continue user interaction with the user. You need not wait for response from the server. Once the response arrives, a designated area in UI will update itself and reflect the response information. Whole page need not be reloaded.

So, you can not access Java Class directly as url to make your Ajax request. It should any mapped url like JSP, Servlets, PHP etc.

Create a JSP (e.g. hello.jsp)

<%
String strResponse;
mail.Main objMain = new mail.Main();
strResponse = objMain.execute();
%>

<%=strResponse %>

In Ajax request

url: "hello.jsp",
