Hello,
I coded a simple Servlet and jsp to learn jQuery Ajax Form submit facility. I used Netbeans to trace the execution of the code. I am sure that the Servlet does send out data as http response. However, the data are not received by the client js code. I don't know why. And, it is very strange that the alert() dialog pops up before the servlet sends out the data completely. Can anyone help me identify the errors?
*** my servlet code (see below) ***
...
public class handlerServlet extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
java.util.Date now = new java.util.Date();
out.print("<p>testing at ");
out.print(now.toString());
out.println("</p>");
} finally {
out.close();
}
}
...
*** my JavaScript code in jsp (see below) ***
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page session="false" %>
