Good day, the situation is as follows: I have a modal bootstrap window where I insert information into the database (PostgreSQL), this action is done from a botón input and a onclick="valida_envia2()" that are inside the modal
This function is found in the jsp:
function valida_envia2() {
if (document.f2.producto.value.length === 0) {
alert("Ingresar Nombre de Producto")
document.f2.producto.focus()
return 0;
}
if (document.f2.precio.value.length === 0) {
alert("Ingresar Precio")
document.f2.precio.focus()
return 0;
}
alert("DATOS GUARDADOS CORRECTAMENTE")
document.f2.submit();
}
these data are entered in the following modal :
<div class="container">
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog modal-lg">

the programming model is MVC therefore I have a model and controller:
MODEL:
package modelo;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.LinkedList;
/**
*
* @
*/
public class mCambiocostos {
int idCambiocostos;
String nombreproducto;
double precio;
double descuentounopro;
double descuentodospro;
double descuentotrespro;
double preciocdes;
public mCambiocostos() {
}
public static int getIdCambiocostos() {
int claveCambCost = 0;
try {
modelo.conexion obj1 = new modelo.conexion();
Connection conexion = obj1.conection();
Statement st = conexion.createStatement();
ResultSet rs = st.executeQuery("select ultimoregistrotcambiocosto();");
while (rs.next()) {
claveCambCost = rs.getInt(1);
}
conexion.close();
} catch (SQLException e) {
System.out.println("" + e);
}
return claveCambCost;
}
public String getNombreproducto() {
return nombreproducto;
}
public void setNombreproducto(String nombreproducto) {
this.nombreproducto = nombreproducto;
}
public double getPrecio() {
return precio;
}
public void setPrecio(double precio) {
this.precio = precio;
}
public double getDescuentounopro() {
return descuentounopro;
}
public void setDescuentounopro(double descuentounopro) {
this.descuentounopro = descuentounopro;
}
public double getDescuentodospro() {
return descuentodospro;
}
public void setDescuentodospro(double descuentodospro) {
this.descuentodospro = descuentodospro;
}
public double getDescuentotrespro() {
return descuentotrespro;
}
public void setDescuentotrespro(double descuentotrespro) {
this.descuentotrespro = descuentotrespro;
}
public double getPreciocdes() {
return preciocdes;
}
public void setPreciocdes(double preciocdes) {
this.preciocdes = preciocdes;
}
The following Model is used to perform the operation that calculates the discount percentage.
package modelo;
/**
*
*
*/
public class cambioC {
String nombre;
double precio, des_uno, des_dos, des_tres, PrecioCDes;
public cambioC() {
}
public cambioC(String nombre,double precio, double des_uno, double des_dos, double des_tres, double PrecioCDes) {
this.nombre = nombre;
this.precio = precio;
this.des_uno = des_uno;
this.des_dos = des_dos;
this.des_tres = des_tres;
this.PrecioCDes = PrecioCDes;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public double getPrecio() {
return precio;
}
public void setPrecio(double precio) {
this.precio = precio;
}
public double getDes_uno() {
return des_uno;
}
public void setDes_uno(double des_uno) {
this.des_uno = des_uno;
}
public double getDes_dos() {
return des_dos;
}
public void setDes_dos(double des_dos) {
this.des_dos = des_dos;
}
public double getDes_tres() {
return des_tres;
}
public void setDes_tres(double des_tres) {
this.des_tres = des_tres;
}
public double getPrecioCDes() {
return PrecioCDes;
}
public void setPrecioCDes(double PrecioCDes) {
this.PrecioCDes = PrecioCDes;
}
}
and finally the SERVLET:
package controlador;

*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
/* TODO output your page here. You may use following sample code. */
int claveCambCost = mCambiocostos.getIdCambiocostos();
String NombProduc = request.getParameter("producto");
String opproducto = request.getParameter("producto");
String claveproduc = modelo.mProducto.getIdProducto(opproducto);
String Preciopro = request.getParameter("precio");
double var = Double.parseDouble(Preciopro);
double var1=0, var2=0, var3=0, PrecioCDes = var;

if (DesUnopro.equals("")||DesUnopro.equals("0.0")) {

PrecioCDes = var - ((var * var1) / 100);
}

if (DesTrespro.equals("")||DesTrespro.equals("0.0")) {
} else {
var3 = Double.parseDouble(DesTrespro);
PrecioCDes = PrecioCDes - ((PrecioCDes * var3) / 100);
}
cambioC Datos = new cambioC();
Datos.setNombre(opproducto);
Datos.setPrecio(var);
Datos.setDes_uno(var1);
Datos.setDes_dos(var2);
Datos.setDes_tres(var3);
Datos.setPrecioCDes(PrecioCDes);
request.getSession().setAttribute("cambioCost", Datos);
String consulta = "INSERT INTO cambiocostos(\n"

+ " VALUES (" + claveCambCost + ",'" + claveproduc + "','" + NombProduc + "'," + var + "," + var1 + "," + var2 + "," + var3 + "," + PrecioCDes + ")";
modelo.conexion obj1 = new modelo.conexion();
obj1.registro(consulta);
response.sendRedirect("Compras/cambiodecosto.jsp");
}
}
This code already allows me to enter the information to the database now I need help to send me to the next modal that sees the code and then prevent the servlet redirecting me to another jsp. (do not perform another action servlet , JSP programming language)
I do not know if this is important, but I have to mention that this modal is generated by means of a button that is inside a table
function add () {
cont++;
var fila = '<tr class="selected" id="fila' + cont + '"onclick="seleccionar(this.id) "><div id="contenido" ><form><td><input type="text" name="codigointerno[]" id="codigointerno' + cont + '" size="10" readonly="true" disabled="true"/></td>';
fila += '<td><input type="text" name="producto[]" id="producto' + cont + '" size="30" onchange="combodetallecompra(' + cont + ')"/></td>'
fila += '<td><select name="presentacion[]" id="presentacion' + cont + '">';
fila += sel_tipopresentacion;
fila += '< /select></td>';
fila += '<td><input name="Costo_ult_compra[]" id="Costo_ult_compra' + cont + '"/></td><td><input name="Costo_prome[]" id="Costo_prome' + cont + '"/></td>';
fila += '<td><input type="text" name="Costo_lis[]" id="Costo_lis' + cont + '" size="20"/></td><td><input type="text" name="Cantidad_Ord[]" id="Cantidad_Ord' + cont + '"></td>';
fila += '<td> <input type="text" name="Unidad_grat[]" id="Unidad_grat' + cont + '" size="10"/></td><td><input type="text" name="costo_sin_iva[]" id="costo_sin_iva' + cont + '" size="10" disabled="true"/></td>';
fila += '<td> <input type="text" name="Total_rec[]" id="Total_rec' + cont + '" size="10" disabled="true"/></td>';
fila += '<td> <input type="text" name="Importe_bruto[]" id="Importe_bruto' + cont + '" size="10" disabled="true"/></td>';
fila += '<td><input type="text" name="Importe_iva[]" id="Importe_iva' + cont + '" class="input" size="10" disabled="true"/></td>';
fila += '<td><input type="text" name="Importe_total[]" id="Importe_total ' + cont + '" size="8" disabled="true"/></td>\n\n'
fila += '<td><button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Costo</button></td></form></div></tr>';
$('#tablaordcomp').append(fila);
}
and effectively when sending the submit () the servlet immediately requests a view, so I require that only the modal be closed and continue within that table.
