AJAX JSP displaying output data in a table
0
trying to display data from server in the page in a table. but unfortunately it is not working. I can display it using out.println. Code samples are attached. Thank you very much.
ajax1 handles the ajax part and ajax2 is the file for java code.

$("#users").change(function()
var value = $(this).val();

$("#javaquery").html(data);

Remove java code from 2nd jsp and add it to a servlet called "AjaxServlet" with url mapping "/AjaxServlet"
AjaxServlet:
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
String q = request.getParameter("q"); //q value
InitialContext ctx;
DataSource ds;
Connection conn;
ResultSet rs;
Statement stmt;
String name = "blank name";
String ename="";
try
ctx=new InitialContext();
ds=(DataSource) ctx.lookup("java:app/jdbc/SalesDB");
conn=ds.getConnection();
String q = request.getParameter("q");
stmt = conn.createStatement(); //Create Statement to interact
rs = stmt.executeQuery("select * from employees where Username='"+q+"'");
while (rs.next())
name = rs.getString("Role_")+rs.getString("username");
ename=rs.getString("username");
rs.close();
stmt.close();
conn.close();
catch (Exception e)
e.printStackTrace();
response.setContentType("text/plain"); // Set content type of the response so that jQuery knows what it can expect.
response.setCharacterEncoding("UTF-8"); // You want world domination, huh?
response.getWriter().write(name); // Write response body.
