I know I have a 64 bit OS, my computer, will simply not download the 64 bit version of java when I hit the big ol' red button on the main page. and yes, I have gone to the downloads page and downloaded the one that's 64 bit, but whenever I try to play games, it simply won't let me go online. I have tried uninstalling and reinstalling, but nothing seems to work.

View Replies View RelatedFor a project I have to create an online survey, I cannot use a per-made online survey system because I have really specific needs that no pre-made system can satisfy, so my idea would be to create it in java and store the data in some simple text file, which are fairly easy to work with in java. My question is, is it possible, and if yes how difficult is it, to put the entire thing online? What worries me isn't putting the applet itself online, but the text files that should collect the data, I already have the website to host it.

MDS don't support all six transaction attributes. MDBs support only REQUIRE or NOT_SUPPORT.... There is no existing transaction to suspend or join when a message is delivered, The two options you have available are REQUIRE if you want a transaction.....
there is no existing transaction when a message is delivered from a queue to an MDB. Why we still need a transaction as it says " REQUIRE if you want a transaction"? When a message is delivered from the queue to the MDB, is this a transaction?
I'm making a website with articles (like a blog). I have a webpage called admin.html where you insert the data of the article (title, post etc).
Admin.html calls to a servlet and this sends the information to a SQL Database and it stores and my index.jsp calls to database and show the articles.
This works perfect, and a non-programmer can insert new articles. The problem is that I need to create an .html file for every article/post and save it into my server online.
For example if I create "CoolArticle", I need the file "CoolArticle.html" and save it in my hosting.
How I can do it? I never have seen examples online, all were local, so I can't continue.

or a carriage return followed immediately by a linefeed.

View Replies View RelatedI'm trying to retrieve information from a json repository stored online. I have so far setup my code to create the string that could be used as the url. What I'm not sure about is how you setup a Json Parser?
- Would you recommend I use a library? I hear google-gson is meant to be good?
- How easy is it to convert a string into a URL? I assumed that this would be good enough
" String searchURL = "randomURL.com"
URL temp = new URL(searchURL);" ,
but I get a MalformedURLException.
- What do I need to know to use JSON?

I am trying to make a calculator using Java GUI. I've managed to make an ActionListener and add it to a button, but I've made an error in my code that I'm unsure of how to solve. Because of how I've written the code, only one number can be placed in the text field. For example, the an ActionListener for the three button on the calculator was added to the button, but no matter how many times the user presses the button, only one 3 will appear in the text field. The code is below:
import javax.swing.*;//import the packages needed for gui
import java.awt.*;
import java.awt.event.*;
public class Calculator {
public static void main(String[] args) {
JFrame window = new JFrame("Window");//makes a JFrame
window.setSize(300,350);
[code].....
As you can see, because the compiler forces the String variable to be final, so when the user presses the button, the code simply shows how a space character and three character would look like, because the String variable can't change. How do I write my code so that every time the user presses the button, a character is added to the text field?
I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?

View Replies View Relatedi am trying to make a platform game in java and to do this im trying to make a scrolling bacground. i can get the background image to scroll. However, i cant get the image to scroll forever, here is the code.
GamePanel class ( the jpanel )
public class GamePanel extends JPanel implements ActionListener{
static ArrayList<BackGround> store = new ArrayList<BackGround>();
public GamePanel(){
setFocusable(true);
Timer time = new Timer(5,this);
time.start();
store.add(new BackGround(0,-200));
the problem i have is that i want the bacground to loop. however, once the first instance of the background is done scrolling it freezes and doesnt load anymore. here is the code for adding a new background to the list
if(store.get(a).getX() <= -950 ){
GamePanel.store.get(a).setX(-900);
GamePanel.store.add(new BackGround(-951,-200));
}
