JSF :: Saving 2 Times One Form
Feb 22, 2014
I'm trying to save to a table in a database that has only 2 fields, (id, nota) . I want to save the data several times just to click on "save" one look . The code that I have is this:
<h:form id="frmPerso" style="font-size: 13px;">
<h:outputText value="Id 1" />
<h:inputText value="#{vistaEjem.notas.id}" />
<h:outputText value="Nota 1 " />
<h:inputText value="#{vistaEjem.notas.nota}" />
[Code] ....
I was told to use a foreach or for the insertDatos, but not as used..

<form method="post" action="updateAccount"
encType="multipart/form-data">
<input type="file" name="file" value="Select image ..." /> <input
type="submit" value="Start Upload" /> <br>
<textarea rows="8" cols="54" name="about">Yes

public class Exercise1{
public static void main(String[] args) {
String employeeName, employeeNumber, position, department ;
double otpay, salary, deduction, hrs, rate ;
Scanner input = new Scanner (System.in);
[Code] ....
That's my codes but its wrong according to our prof. it should be in frame form. i don't know how to do it since i did not encountered framing since i was started in java.

I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.

I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
Code before:
<td><input class="buttonred" type="submit" value="Confirm Add" name="submit_message"></td>
<s:form action="upd-message" method="POST" validate="true" onsubmit="validateMsg();return false;" enctype="multipart/form-data">
function validateMsg() {
var frm = document.forms["upd-message"];
frm.actionType.value=message;
[Code] .....

How can I store in database an user Session attribute along with other informations provided in the same form?
<p:outputLabel value="user ID:" for="informer" />
<p:inputText id="informer" value="#{session.getAttribute('userID').toString()}"
title="informer" disabled="true" />
I've already tested with disabled="false", too, but only the Session attribute is saved as NULL, though it appears in the form field. The other fields are saved properly.

What I am trying to do is save the the content drawn to my screen as an image. The following code is my render method and although I know how to use it, I don't fully understand the classes and how they work with is making this difficult.
public void render() {
BufferStrategy bs = this.getBufferStrategy();
if (bs == null) {
createBufferStrategy(3);
return;

So I'm still learning how to save data using Java. I know that saving data is extremely important when it comes to creating video games.
What I have here is this simple program.
Java Code:
import java.util.*;
import java.io.*;
import java.lang.*;
public class Character
{
private Formatter x;
private int roomNum;
private boolean[] visited = new boolean[10];
[Code]...
I'm trying to make sure that after I exit the program, joe starts in room 4, not room 1, and that he has visited rooms 1, 2, 3, 4, and 10. I have the save data created, but how do I save an array of boolean values?

recently I was playing a lot in Eclipse, testing util classes, randomisation etc. But always when I wanted to keep something for future reference, I had to either comment it out or start a whole new class, copy all the code and change just that little thing I was testing.I was wondering if it's possible to actually save just the 'current state' of the code. The idea came back from my days when I was working with 3ds max and I saved the scene periodically so I could revert back anytime I messed up something.
I was looking into Object Serialisation and JUnit testing for this purpose, but that's just too complicated. Is there a way in Java (Eclipse) to accomplish such thing?

I have the following
Java Code: list.stream().sorted((s, s1) -> s.getName().compareTo(s1.getName())).distinct(); mh_sh_highlight_all('java');
I want to save the results to a collection.
I saw an video tutorial on these by Oracle learning library and they mentioned an into(collection) method but I looked at the api and there isn't one.
How can I do it?

in my web.xml the.STATE_SAVING_METHOD setting is server
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>
for measurement of application security isn't not allow to change this parameter to client , so the problem when I access for application and I open a new page via linker for print for example and I would access for my initial page to make change or modify my initial page it s no possible to make any modification because I have a empty bean , but if the state saving is a client I haven't a problem because a tree map is stored in client browser, so my version of JSF is 1.1.1 ,

I have a simple project to save data to the database. I have successfully mapped the java class with the database table. The code displays no error, it runs very well but it does not save to database, instead it catches an exception and prints out "saving failed". The database is a mysql database.
This is the managed bean code. Save.java(name=bean)
//imports
@ManagedBean(name="bean")
@RequestScoped
public class Save {
private String username,password,msg;
Session session = null;
Transaction transaction = null;
//GETTERS AND SETTERS
public Save() {

I am trying to make a program where a user can enter guests name for a hotel, the JTable includes rows for the name of the tenant, the room number, month etc.
I've made the table, however I am having some trouble in saving the data that I put into the table. I used jtextfield and a jbutton to but data into the jtable. I am trying to save the data, and load it just buy clicking a button.
table.setModel(new DefaultTableModel(
new Object[][] {
},
new String[] {
"Room", "Name", "Month", "Payment"//table rows
}
));
This is my basic table. And what I'm trying to do to save the data is:
DefaultTableModel model = new DefaultTableModel();
private JFileChooser myJFileChooser = new JFileChooser(new File("."));
private void saveTable() {
if (myJFileChooser.showSaveDialog(null) ==
JFileChooser.APPROVE_OPTION ) {
saveTable(myJFileChooser.getSelectedFile());
[Code] ....
When I run my program, I'm able to click on a button, and the dialog box will appear, I'm also able to save the data to a file. However when I click on the retieve data button I made the dialog box opens, the file is there, however when I click it, nothing happens.

I've tried everything but in vain..I want to save the data from the table into the database, I can easily connect to the database. All I want is how to get the values from the table. I've tried this method to get the values but its not working because of the contructor error in the BgTableModel class.
Tried Method
public void writeBgEdu() {
int last=gtm.getRowCount();
System.out.println(last);
for( int i=0;i<last;i++) {
if(((String) gtm.getValueAt(i,0))!=null)

Everything compiles but doesn't work like it should. What the idea is, is to be able to add class personnel objects and have them saved in a file, so that later on i would be able to see them.
Back to my problem: When i create a new "Personnel" and try to run Write and read, to see if my new "Personnel" is added to the list, it's not there at all... what do i do wrong?
import java.io.*;
class Personnel implements Serializable
//No other action required by Serializable interface.
{
private long payrollNum;
private String surname;
private String firstNames;
[Code] ....

So, I have two classes (bubble sort and insert sort) which are sorting dates. I need to save their comparings and reallocation of elements.
And I don't know how to do it. The point is if I want save that dates(comparings and reallocation) to Result class i need to create new instances of class in each sorting classes so i can't later do something with that, because I have null in Main class.
To avoid that problem i have tried to make Result class as singleton.. I mean: "public static final Results INSTANCE = new Results();" and then in classes "static Results result = Results.INSTANCE" without constructor and to save for example comparings i had method:
Java Code:
int SetComparings(){
return comparings++;
} mh_sh_highlight_all('java');
But it do not work too, because it overwrites old dates. Is there anyway to do not create instance of class? I don't want to copy whole code because it is too long and cant be unreadable, but i will put you structure of my program:
Java Code:
class BubbleSort{}
class InsertSort{}
class Results{}
class Sorting{} // class with switch to choose which way of sorting use
public class Main{} mh_sh_highlight_all('java');
