Bootstrap remote validation not work properly with java

wish helps you the data your sending back to the bootstrap validator is not in correct json format. Change it to correct json format and I will work. This worked for me . Change it according to ur requirement public class RegistrationEmailCheck extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("application/json");
PrintWriter out = response.getWriter();
JSONObject json = new JSONObject();
String availEmail = request.getParameter("email");
System.out.println(availEmail);
String SQL = "SELECT email FROM login WHERE email='" + availEmail + "'";
Connection con = DBInfo.getConn();
Statement st;
ResultSet rs;
try {
st = con.createStatement();
rs = st.executeQuery(SQL);
if (rs.next()) {
out.print("{\"valid\" : false }");
json.put("valid", false);
System.out.println("false");
} else {
out.print("{\"valid\" : true }");
json.put("valid", true);
System.out.println("true");
}
} catch (Exception ex) {
ex.printStackTrace();
} finally {
out.close();
}

Struts2 validation is not working properly, validation error messages not shown
Date : March 29 2020, 07:55 AM
wish of those help After having read how the INPUT result works and having abandoned the ModelDriven design pattern that adds nothing to your programming experience except problems, that might easily hide themselves in the middle of the Interceptor Stack, note that: redirect is the result to use when redirecting to external URLs or non-Action URLs, while redirectAction should be used when redirecting to an Action; when redirecting, a new request is created, and hence the old parameters (including action errors and messages and field errors) are lost.
