    Thanks for your suggestions, all ready tried the task manager but get programme not responding.

    Tried Google Chrome but the programme for Golf Solitare took about 7 mins to download as opposed to almost instantly on AOL.

    I've got the same problem, eroor message comes up when I want to close the window ( Tried updating Java, no help at all with the problam and to make matters worse my mouse and keyboard keep locking/freezing up since i've had this problem, they lock for about 30 seconds then they're ok until you don't use them for a minute or so. Running Vista Home 64bit, IE7, also having the same problem on firefox and safari. Mouse and keyboard are wireless entertainment pack 7000, been running all this for nearly 8 months without a hitch, then had a problem with IE7 shutting down all the time, moved across to firefox had the same problem, lived with that for a while but got fed up with it, went to reinstall IE7 and spotted IE8.... Like a prat downloaded this, thinking newer is better! Needed to reload Java to work with this and had problems ever since and on top of all that IE still keeps closing for no reason.

This sounds like it could be a case where a simple error in the game is allowed to have enormous consequences. Rather than disconnecting your Internet connection, it may suffice to terminate the java process as follows:

  • Right-click the task bar. Click Task Manager.
  • In the Processes tab of the Task Manager, find java.exe (it might help to click on "Image Name" to have it sort alphabetically)
  • Select the line with the image name of java.exe and click the "End Process" button in the lower right corner of the window.

Have you tried running these games in a different browser? I recommend Mozilla Firefox or Google Chrome. Both are more robust than AOL Explorer, and Google Chrome in particular is designed so that an error in one tab won't cause any problems beyond that.

Please let me know if this helped. If it didn't, feel free to provide more details.

    Regarding Google Chrome: it uses a different cache than AOL Explorer, so it would probably take a long time the first time to download any particular game, but after that it ought to load fairly quickly. The same would be true of Firefox.

How to make a program of games using java?

The Java Game Development Tutorial After a lot of hard work, we have made it to finish the English version of the tutorial. As I said, you should be already able to program in Java, although you don't have to be a expert! The tutorial will give you a very detailed introduction into the development of online games using Java. We will talk about Java Applets because everyone has a Internet browser, so everyone is able to play these games without installing the JDK! The first 5 chapters will lead you from the basic structure of a applet to the development of a whole (although pretty small) game. The next chapters (6 - ...) will give you solutions to problems like AI, level editors, random generation of landscapes... . At the end of every chapter you'll find a link to download the sourcecode of the applet we programmed in this chapter and you can take a look at the working applet too. Alright, here we go!
  • Basic structure of an applet
  • Animation
    1. Move a ball
    2. Double buffering
    3. Ball bouncing and change the direction
  • Sound and Gif's
    1. Using sound in applets
    2. Using pictures in applets
  • Event handling in applets
    1. Mouse events
    2. Keyboard events
  • The first complete game
    1. Outline of the program and structure of classes
    2. Random movement of the ball
    3. Hit a ball by clicking on it
    4. Count score and loose lifes
    5. Change the mouse pointer
    6. Start the game after double clicing on the applet
  • Advanced topics
    1. Artificial intelligence for a pong like game
    2. Generation of random 2D landscapes
    3. Leveleditor

    What is J2ME?

    Java Platform, Micro Edition (Java ME) provides a robust, flexible environment for applications running on mobile and other embedded devices—mobile phones, personal digital assistants (PDAs), TV set-top boxes, and printers. Java ME includes flexible user interfaces, robust security, built-in network protocols, and support for networked and offline applications that can be downloaded dynamically.

    Java-problem in Firefox

    I think they meant the software altogether.
    Here's the link, just install.
    If you already have java then repair your IE and reinstall Firefox.
    Click Start, then Control Panel, then Add/Remove Program, go to Internet Explorer, right click IE then select repair.
    Do the same thing for Mozilla Firefox, except this time uninstall then reinstall program.
    That might work. Let me know.

    Incase it's easier in Dutch:
    Ik denk zij de software totaal betekenden. Hier is de verbinding, installeer enkel. Als u reeds Java toen uw Internet Explorer herstellen hebt en Firefox opnieuw installeren. Klik Begin, dan Controlebord, dan voeg/verwijder Programma toe, gaan naar Internet Explorer, met de rechtermuisknop aanklikken Internet Explorer, dan uitgezochte Reparatie. Doe het zelfde ding voor Mozilla Firefox, behalve deze tijddesinstallatie dan installeer programma opnieuw. Dat zou kunnen werken. Laat me het weten.

    I believe the error should read "java.lang.NullPointerException"

    This error simply means that whatever your application code is trying to get is not there- its a null. Its either out of range or does not exist at all.
