    Question Can't retrieve Jtext Field values from another frame..

    i m trying to retrieve jtext fields and combo box values from another frame and to put them in database but .getText() doesn't return anything please help me thanx in advance

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
             try{
           String sql = "select * from login where uid = ? and pass = ?";
           pst = con.prepareStatement(sql);
           pst.setString(1, jTextField1.getText());
           pst.setString(2, jTextField2.getText());
           rs = pst.executeQuery();
            if(rs.next()){
                JOptionPane.showMessageDialog(null, "username and password is correct ");
               if(products.addProduct==true){
                   products p = new products();
                   p.addProduct();
                   products.addProduct=false;
               }
            }else{
                JOptionPane.showMessageDialog(null, "username and password is not correct ");
     
            }
     
     
     
        }catch(Exception e){
            JOptionPane.showMessageDialog(null, e);
        }
        }


    this is a password frame that calls addProduct() method from products class if password is correct.
    Here is addProduct() method


    public static void addProduct(){
        try {
                int Productid = getProductTypeId(combo_Type.getSelectedItem().toString());
     
                pst = con.prepareStatement("insert into product(pName,Product_type_id,pCost,pPrice,pQuantity,pModel,pCompany) values(?,?,?,?,?,?,?)");
                pst.setString(1, txt_Product_name.getText());
                JOptionPane.showMessageDialog(null, "txt_Product_name is "+txt_Product_name.getText());
                pst.setInt(2, Productid);
                JOptionPane.showMessageDialog(null, "getProductTypeId is "+txt_Product_name.getText());
                pst.setString(3, txt_Product_cost.getText());
                JOptionPane.showMessageDialog(null, "txt_Product_name is "+txt_Product_name.getText());
                pst.setString(4, txt_Product_price.getText());
                JOptionPane.showMessageDialog(null, "txt_Product_name is "+txt_Product_name.getText());
                pst.setString(5, txt_Product_Quatity.getText());
                JOptionPane.showMessageDialog(null, "txt_Product_name is "+txt_Product_name.getText());
                pst.setString(6, txt_Product_model.getText());
                JOptionPane.showMessageDialog(null, "txt_Product_name is "+txt_Product_name.getText());
                pst.setString(7, combo_brand.getSelectedItem().toString());
                JOptionPane.showMessageDialog(null, "txt_Product_name is "+txt_Product_name.getText());
                pst.execute();
     
                JOptionPane.showMessageDialog(null, "Saved");
            } catch (Exception e) {
                JOptionPane.showMessageDialog(null, e);
            } finally {
                try {
                    pst.close();
     
                } catch (Exception e) {
                    JOptionPane.showMessageDialog(null, e);
     
                }
     
            }
            Update_Table_Products();
    }

    Welcome to the forum! Please read this topic to learn how to post code correctly and other useful info for new members.

    Use print statements or other debugging tools to determine the results of method calls on desired components. Then, if the contents are not being collected and reported properly, back up and find out why. Otherwise, post a workable example that demonstrates the problem with the least amount of code possible.

    thanx for your reply GregBrannon i m using print statements in addProduct() method when it is called the method is invoked successfully but in this the print statements which shows the values of text fields and combo boxes returns default values , for example null for string and 0 for integers.

    There aren't any obvious problems with the code you've posted. Post runnable code that demonstrates the problem. It also isn't clear how your question is related to the thread title, so it would be helpful if you'd describe or give an example of the overall design so that we can see how one container or component is gathering data (or trying to) from another.

    Thanx GregBrannon again but i found the problem, the method addProduct() was not returning the values of text fields, i was invoking a static method using an instance of the class in which the method resides , now i corrected by invoking directly using just class name now its working fine ..and sorry for my bad English
     products p = new products();
                   p.addProduct();
                   products.addProduct=false;

    it was my first code and i make it write using

                   products .addProduct();
                   products.addProduct=false;
