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.

When we have a jsf form to store clients in a ddbb for example and the backing bean is in session scope.... Lets think of a user that requests 3 times the xhtml view with the form to store 3 clients.
1) If we dont reset the backing bean each time the form is processed, he would see the values he sent beforea and it doesnt have much sense, right?
2) Here there is an example of clearing form after submitting : [URL] ...... Clearing the form after submititng is a common practice for the reason of the statement 1, right?
3 ) What is the best or normal approach to reset values in a form? when the user requests it or done automatically by the application after processing a form?
4) Are there known issues about resetting or not resetting the values in a form bean?

I written java code in JSP to display data. I know it is bad practice. Actually my Business-service communicates with DB and returning data in the form of MAP. I don't have beans Because the fields in DB is dynamically changing. So, for now I'm retrieving Data by writing Java code in JSP. Is there any other way to display data without writing java code in JSP?

I have the following simple "selectManyCheckbox" specified in my jsf page:-
<h:selectManyCheckbox id="animalsmc" layout="pageDirection" value="#{animalSelectionBean.selectedAnimals}">
<f:selectItem itemValue="1" itemLabel="Lion"/>
<f:selectItem itemValue="2" itemLabel="Tiger"/>
<f:selectItem itemValue="3" itemLabel="Elephant"/>
<f:selectItem itemValue="4" itemLabel="Eagle"/>
<f:selectItem itemValue="5" itemLabel="kangaroo"/>
</h:selectManyCheckbox>
I have the following specified in my bean class:-
private int [] selectedAnimals;
...
public int[] getSelectedAnimals() {
return selectedAnimals;
}
public void setSelectedAnimals(int[] selectedAnimals) {
this.selectedAnimals = selectedAnimals;
}
I would like to know how to display the values of selected checkboxes on the JSF page after submitting the form? I tried outputtext, however it displays the object and not the values. I cannot even frame the outputformat for the same.

I'm trying to create a Servlet that takes input from a form and process it and insert it in database.tablename.
My MAIN ISSUE IS WITH THE NUMBER OF COLUMNS THAT WOULD BE DYNAMIC AND THUS CANT RECEIVE THE PARAMETERS IN STATIC CODE.
Here is the form code
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<form action="Test" method="post" />
<table width="90%" border="1" cellspacing="1" cellpadding="1">
[Code] ....
And here is the Servlet
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.io.*;
public class Test extends HttpServlet {
[Code] ....
This is the basic code structure and I'm trying to figure out this special case with handling the multiple parameters:
I don't want to use String []a=request.getParameterValues("studentname"); as hard code. The reason being the number of rows will be diyamic and I would like to get the column name and then then use an array of string to take values. But how can I connect these to form a query so that the rows goes on inserted one after other.

a simple Java program for finding the median value in a list of values with the following requirements:
- Create an array with an even number of values in it (an odd number of values is little bit trickier, so if you want a challenge, do it for either an even or odd number of values)
- Find the value with an equal number of values greater than the value as there are values less than the value
- Your solution must not require a sorted list of values - Output the median value
This assignment is intended to get you to demonstrate basic knowledge of arrays, and to create methods with both input and output.

My project consists of a web app where a user can select a area from a picture and f.e. if it is a office layout he can input the worker name and any peace of hardware that the area might have. In this case there are two categories: Hardware and Computer. Hardware - it has 5 dropdown lists consisting of printer, scanner and etc. Computer - like Hardware consists of many dropdown lists which add up to components such as processor, motherboard and etc. For me, considering this is my first ever web app project, is a huge step towards web development, I have used various mixes of Java, javascript and primefaces code.
My current problem: When a user selects an area he gets a dialog box where he is prompted to select his desired input, afterwards the user clicks the 'save' button and get's another dialogbox which has a resume of what he has selected so he could check out his input and save it by clicking the 'save' button in the resume box. My problem is that when the user clicks the save button the button calls a method which takes all the input and creates an Area object (Area object consists of various objects such as: Coordinates, Dimensions, Employee, ComputerList and HardwareList) and sends a query to the database, but all the values I get is null.

I am generating textfields dynamically using JSTL forEach. Here is the code ..
<c:forEach var="underlyingTickers" items="${underlyingTickersList}" >
<tr>
<td ><input name="underlyingTickers" type="text" id = "underlyingTickers" value="<c:out value='${underlyingTickers}' />">
</td>
</tr>
</c:forEach>
If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.

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;

I would like to draw a rectangle around a certain part of an image.
So I wrote this:
Pixel[] pixels = scene.getPixels();
for( Pixel pixel : pixels)
{
if(pixel >= point.getX() && pixel <= (point.getX()+p2.getWidth())
{
pixel.setGreen(150);
}
}
But the error is giving me incompatible types. I would like to set all the pixels at a certain point up to the dimensions of my rectangle and so on. How would I do that?

I'm using jsoup to parse a calendar page.
I want to use a switch or if/else statement to filter out the data I don't need for the app. This is by no means anything more than a draft because java is easier to work with than android.
Element table = doc.getElementById("launch_calendar");
Iterator<Element> iterate = table.select("td").iterator();
if(iterate.hasNext()){
for(iterate.hasNext();;){

I have quite a specific view for how I want my components layed out. No matter what I try I can get them to display how I want! I'm using three JPanels. There's a main panel that goes inside the tabbed pane. This main panel contains two other panels. The First panel is a gridbaglayout panel, with labels on the left column, and components on the right column. The second panel is underneath the second, and contains a label, and a button beneath it. THis uses a basic box layout, with one component per line. The label doesn't always appear (depends if a component is changed). With everything showing, this is how it looks so far:
However, I want the Labels on the left of the pane. The right hand column should be aligned horizontally and have more space from the labels. Ideally I'd like a gap between the last label/checkbox and the Note label.
This is my current code for the panel/s inside the tabbed pane window.
videoPanel = new JPanel();
applyVidBtn = new JButton("Apply Settings");
applyVidBtn.setVisible(false);
warningLbl = new JLabel("Note. Applying these settings causes a program restart.");
warningLbl.setVisible(false);

This program simply adds integers to an ArrayList and then prompt the user if they would like to delete specific numbers that they don't want.
The output that I get when I want to delete numbers like 2 and 4 from 1 2 3 4 5 is 1 2 3 4 5 instead of 1 3 5.
Java Code:
import java.util.ArrayList;
import java.util.Scanner;
public class AL
{
// A regular array like int arr[] has to have its size declare before run-time and it's not dynamic which mean it can not grow or expand on its own.
static Scanner input = new Scanner(System.in);
// You have to use reference types(Integer, Double, Float); not primitive types(int).

We currently have an application which uses JDBC to connect to the backend database (DB version - 11.2.0.3 ). The application uses a properties file in which the password for the db schema is hardcoded in plain text format. Due to security restrictions we have been asked to make sure the password is encrypted in the file and no direct access is made to the schema using the plain text password. Best options we can use to make this password encrypted both at Oracle DB side and Java side.
