I'm new to JSP but I've to use it to grab data coming from an external site, pass data to a Bean, write data in a DB and redirect the user to another page. Follow the JSP page.
<%@page import="EJB.getResponse"%>
<%
long paymentID = Long.parseLong(request.getParameter("paymentid"));
String responsecode = "9999";
getResponse g = new getResponse();
[Code] ....
This is the bean:
@ManagedBean
@RequestScoped
public class getResponse implements Serializable {
private Long paymentId;
private String result;
private String auth;
[Code] ....
On the console I see the prints but I receive the NullPointerException
WARNING: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
at EJB.getResponse.printData(getResponse.java:72)
at org.apache.jsp.notify_jsp._jspService(notify_jsp.java from :60)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:111)

How are methods invoked on the `bird` parameter?
next.xhtml:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
[Code] ....
`MyQueueBean` is intended to give out a bird once only, to exactly one end-user. Because it's application scoped, and not session scoped, getting attributes directly from the bean would give inconsistent results.
The birds application is from Facelets Essentials Guide to JavaServer Faces View Definition Framework: [URL] ....
how is the variable passed to the file? Once it's passed, how is it referenced?

I have an application and I would like it to send a file to a web page using POST method.
I've found the HttpClient from Apache, but I had no luck. All the tutorials and samples I can find on the net are for 3.x. I've tried adopting the samples with the HttpClient 4.1 docs, but I failed.
I have a target url of a page and source file path. I get the basic idea of what needs to happen, I am just finding it hard to implement it.

I have a JSF page (called MainPage) with a commandButton: clicking on it, I open a modal panel with a <Rich:fileUpload> component, related to a listener in corresponding bean.
When I start to upload a file, page MainPage starts to refresh, but I would like to prevent this because it's not necessary.
I tried to "play" with <Rich:fileUpload> property values, but nothing seems to work and I don't know what to do anymore.
Here is file upload component
<rich:fileUpload fileUploadListener="#{pannelloUploadBean.uploadListener}"
id="#{cid}_input"
ajaxSingle="true"
immediateUpload="true"
listHeight="200px"
listWidth="458px">

The main method should creates a Student object with name as "Bill" and marks as {88,92,76,81,83} and print it.
Java Code:
class TestStudent {
public static void main(String args[]) {
Student1 st = new Student1();
st.name = "bill";
Student st1[] = new Student[6];
//This gives error
st1[].marks = {1, 5, 8, 9, 7, 6}; mh_sh_highlight_all('java');

I understand the stack part of it, just not the loop, specifically how you give the user more than one option to input.
Implement a printer driver that handles incoming print jobs. The driver will behave in the following manner:
- Loop giving the user the following options: ADD print job, DELETE latest print job, and
QUIT
- Recording the following information from each job: computer name, document name, and
number of pages
- When the user chooses to ADD, add a new print job to the top of the stack
- When the user chooses to DELETE, pop off the latest print job and output to the screen
which job has just been deleted
- When the user chooses to QUIT, output the print jobs still in the stack (in order from top
to bottom)
- Output must include all relevant information for each job.

I found an exercise online to create a small program . I have this code that I have done so far:
import java.util.Scanner;
public class Test {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
long a = sc.nextLong(); long b = sc.nextLong();
long count = 0; // counter
for (long c = a; c <= b; c++) {
if (c % 2 == 0 || c % 3 == 0 || c % 5 == 0) {
count++;
}
}
System.out.println(count);
}
}
This program is suppose to give me the number of numbers which are dividable by either 2,3 or 5 in a range of a to b, where a<=b.
FOR EXAMPLE: a=5 b=8 ... output: 14 (since there are 14 numbers in between 5 and 8 which are dividable by either 2,3 or 5.)
It works great for all of the numbers except higher ones such as a=123456789012345678 b=876543210987654321. Here it doesn't give me any output. From what I know it is because the code is still running. But there must be a quicker way ...something that can modify the code so it finishes in the matter of seconds not hours. Something that will fasten the process of checking if the numbers are dividable...

I'm having trouble in 2 areas.
I'm trying to draw 3 triangles 'on top' of each other to give appearance of a tree. My code is below and struggling with how to set my x/y cords correctly.
Also I've drawn a rectangle under a new class and that should then be appearing in the south location of my border layout (south) - but it's not.

I have a program with a main panel JPanel that implements KeyListener. I added a JTextArea to which I added as the KeyListener: this, meaning the main panel. I made the JTextArea fill the entire main panel because I want to catch a key press anywhere in the main panel.I catch the key presses and the program does what I want it to.
I added a JToolBar to the program; it is working just fine.Now that I have two components on the main panel - toolbar and panel with textarea -, the textarea must have the focus before it will send the KeyEvent and call keyPressed(). I don't want to expect the user to click on the main window to get the program to start or after each time they use the toolbar.
I have tried calling both requestFocus() and requestFocusInWindow() on the textarea; neither call worked. I put the toolbar at PAGE_END instead of PAGE_START; this worked to allow the program to start but I don't want to have the toolbar at the bottom and once I clicked on a toolbar button, the textarea lost the focus.
I need to be able to give the textarea the focus when the program starts and after the user uses a toolbar button. (I suspect that if I solve the problem when the program starts, I can use the same method after handling a button press.)

I've been working on a program where you can interact with the computer and play a guessing game of numbers between 1 and 100. It's mainly finished, I just need to add in my comments and stuff. My one problem about it that I cannot figure out is trying to get the results to give the correct int. At the end of the game, it's supposed to return the user information about how well they did like this:
Overall results:
total games = int
total guesses = int
guesses/game = double
best game = int
best game should give you the least amount of guesses you had during a particular round of the game. Here is what I have so far:
import java.util.*;
public class Guess {
public static final int MAX = 100;
public static void main(String[] args) {
intro(MAX);
Scanner console = new Scanner(System.in);
int tempBestGame = 0;

javax.xml.parsers.DocumentBuilder can build a document from a single stream which is the XML file. However, I can't find any way to also give it a schema file.
Is there a way to do this so that my XPath queries can perform type aware queries and return typed data?
We presently use dom4j/jaxen and it does this fine but I figure we should switch to the standard Java runtime if this has been added.
