Backspace in JAVA Applet - How to fix

I am running RedHat 7.2 and everything on my keyboard works normally.
However, when I start the Crossword Puzzle applet (in the Games section) in Yahoo, the Backspace key does not function the same way as it does everywhere else. In particular, I have to use the Ctrl-H keys to perform a move left + character delete.
Is this a problem isolated to this applet (Crossword Puzzle) or is there a general place to look to set the keyboard keys when a Java applet is running?
Thanks in advance for any help.
Donald

I have tried most of the browsers in both RedHat 7.2 and Mandrake 8.2, and with both Gnome and KDE desktops. Some of the browsers would not run the applet.
I have the problem with Netscape 6.22, with Java plugin 1.3.1_02-b02
This browser is the latest version. I am not sure about the Java plugin.
Regards,
Donald

UDPDatagramConnection is available under MIDP/Midlet. But after migration to j2se, it shows microedition does not exist. What is that mean?.. None of the J2ME (or JME - I forget what they're calling it this instant) classes are available in J2SE ((J)Applets, (J)Frames etc.).
Usually there is a J2SE equivalent. The JavaDocs for J2SE are available for download, or for web browsing at [http://java.sun.com/javase/6/docs/api/index.html]. I say usually since I can find no letter for letter equivalent of UDPDatagramConnection in the J2SE. There are a variety of classes that mention Datagram. Perhaps if you start there, you will figure how to do what J2ME does.
..i want to switch the same code, concept, in to j2se.
rtpCon = (UDPDatagramConnection) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();BTW - the advice to use code tags still stands. Most people will not so much as glance at code that is not formatted. After all, which is easier to read, this..
rtpCon = (UDPDatagramConnection) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();
..or this?
rtpCon = (UDPDatagramConnection) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();

On a Mac Java applets not working on FF 31, have not worked since FF26; how to fix?

KeepVid, Quietube, Pin It, and placeholders on most websites instead of Java applets. Running Mavericks and Mountain Lion on an iMac and MacAir, and the applets don't work on either - they haven't worked since FF26. Plug-in is installed, and "always activate" in on. Anyone know what's going on and how to fix this?

I know of two settings associated with Java, maybe we can start there?
About:addons and then go to "extensions". Look for the Java plugin and make sure it is activated.
After this you can go to the Java options to make sure that it is active and check if it is up to date here [https://www.mozilla.org/en-US/plugincheck/]
[https://support.mozilla.org/en-US/kb/how-allow-java-trusted-sites How to allow Java on Trusted Sites in Firefox] may also be helpful.

When using Java Wizard with Firefox 3.6.23 on a Mac OS X 10.6.8 it keep getting an error message: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem." Have NO idea how to fix this problem.

When trying to upload files I received the following error: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem."

If the problem is with a site that is hosted using MOVEit DMZ by Ipswitch, please notify the site owner of the issue and ask them to apply the patch that is available on the support site to resolve the issue.
This is a better resolution than downgrading your version of Java that was updated due to security issues.

How to get started on java applet client/server game?

Hi,
I've googled, but didn't find any useful information about creating java applet client/server game. I've followed the example of Client/Server Tic-Tac-Toe Using a Multithreaded Server in Java How to Program from Deitel, but I when I tried on Applet, my cliet doesn't communicate with the server at all. Any help to get started with Applet would be great. Thanks!

well, i decided to put in portion of my codes to see if anyone can help me out. the problem I have here is the function excute() never gets called. here is my coding, see if you can help. Notice, I'm running this on Applet thru html page. This shouldn't be much different than running JFrame in term of coding right?
Server.java
    public void init()
        runGame = Executors.newFixedThreadPool(2);
        gameLock = new ReentrantLock();
        otherPlayerConnected = gameLock.newCondition();
        otherPlayerTurn = gameLock.newCondition();
        players = new Player[2];
        currentPlayer = Player1;
        try
            server = new ServerSocket(12345, 2);
        catch (IOException ie)
            stop();
        message = "Server awaiting connections";
    public void execute()
       JOptionPane.showMessageDialog(null, "I'm about to execute!", "Testing", JOptionPane.PLAIN_MESSAGE);
        for(int i = 0; i < players.length; i++)
            try
                players[i] = new Player(server.accept(), i);
                runGame.execute(players);
catch (IOException ie)
stop();
gameLock.lock();
try
players[Player1].setSuspended(false);
otherPlayerConnected.signal();
finally
gameLock.unlock();
Client.java
    public void init()
        startClient();
    public void startClient()
        try
            connection = new Socket(InetAddress.getByName(TienLenHost), 12345);
            input = new Scanner(connection.getInputStream());
            output = new Formatter(connection.getOutputStream());
        catch (IOException ie)
            stop();
        ExecutorService worker = Executors.newFixedThreadPool(1);
        worker.execute(this);
    }So after worker.execute(this), it should go to Server.java and run the function execute() right? But in my case, it doesn't. If you know how to fix this, please let me know. Thanks!

How do I set it to where the java applets will load up?

Uhm.. So, I've gotten the 6.0 java, at first the java applets were doing fine and loading up with Firefox. I have checked the java console and it is set for fire fox, yet it's still not loading the applets. Any suggestions on how to fix this problem?

Your above posted plugins list show that you have the Java plugin.

I am trying to use an education program that needs Java applets to install and use and it will not use Safari. When I download IE from the web it will not install. How can I get a browser that will work on my MacAir for travel use of this program?

I am trying to use and education program that needs Java applets and it will not run on Safari. IE will not install from the web. How do I get a browser that will work to install so I can use this program when I travel.

Try using FireFox. IE will only run on a Mac if you run Windows on the Mac.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox. Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

How to update content of a file on server using a Java Applet?

Hi,
I'm new to Java, and I have a task now to overwrite a text file on a server using an applet. I have written a piece of code which compiles but doesn't work. Can you please take a look at the code or give me another way to do it?
Thanks.
Code:
import java.applet.Applet;
import java.io.*;
import java.net.*;
public class test2 extends Applet{
public void init() {
StringBuffer buf = new StringBuffer();
try {
     String output = "this is some string";
     URL aUrl = new URL (getCodeBase().toString() + "test.txt");
     System.out.println(aUrl);
     URLConnection con = aUrl.openConnection();
     con.setDoOutput(true);
     PrintWriter out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(con.getOutputStream())));
     out.println(output);
     out.close();
catch (MalformedURLException mue) {
     System.out.println("improper url");
     mue.printStackTrace();
catch (IOException e) {
     System.out.println("io exception");
     e.printStackTrace();
}

Thanks. I knew there would be a security issue, but I do not have sufficient knowledge to get around it. If you have a reference how to configure a server please post it here.You need to create Signed Applet. Because normally applets have some restriction to access the files in the client machine. Signed applets overrides the restriction.
To know more, Read [url http://192.9.162.55/developer/onlineTraining/Programming/JDCBook/signed.html]Signed Applet
No. Our OP wants to write to the server, not to the client! And to achieve this from an applet, you don't need it signed, iff the server is the machine from where the applet was downloaded in the first place. You only need to use a mechanism that allows you to write to servers, which HTTP is not. FTP, on the other hand, if setup properly can do it. So instead of trying to write using an HttpURLConnection (OP's attempt), you would use an FTP client library. FTP here is just an example and probably not the best way. Another option is to use some servlet or PHP or ASP on the server side and the applet will sumbmit the changes to that code on the server, which in turn will write to the file. The idea is that you need some 'partner code' on the server, be it the FTP server or the servlet/PHP/ASP code. None of this requires the applet to be signed.

How do I clear all of the java applets that have been downloaded?

I migrated firefox and other applications to my new mac so that I would not to reenter all of my passwords saved by firefox. However, it appears that the java applets were also transfered and one of these applets does not work with the new intel mac. I was able to get the same applet to work in safari, and I was able to delete the applet from safari as well, but was unable to do so in firefox.
So, how do I clear all of the previously downloaded applets, or even better, just the one I want to? Clearing all of the recent history didn't work.
Here is the site:
http://www.mdbg.net/chindict/chindict.php
== This happened ==
A few times a week

I did that already, and it cleared the applets for Safari, but not for Firefox.
