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.

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.
