Can't open Java Plug-in 1.3.1_01 control panel

Click on the Java Plug-in icon, my cursor turns into an hour glass for a few seconds, a javaw.exe process starts on my Windows2000 Pro Task Manager, but the Java Control Panel never appears.
Also click on other java icons and the same thing happens (a javaw.exe process starts but not window appears).
Same thing happens with 1.4.1_01.
Any ideas on what could cause this?
Thanks.

Any ideas on what could cause this?Not really, but try uninstalling and reinstalling the JRE.

Java plug-in 1.4.1 proxy configuration issue causes JTextField TAB problems

I have an applet that has multiple JTextFields in it. I recently updated my Java plug-in to version 1.4.1, and now using TAB to navigate among text fields does not always work when I first bring up a browser and load the applet.
I've found, however, that if I open the Java Console and hit "p" (reload proxy configuration), and then reload my applet (hit Refresh/Reload on my browser), the Tab key works as expected. I did not have this issue with releases prior to 1.4.1.
Any clue on how I can ensure proper proxy configuration upon initial instantiation of the browser? I've seen the problem in both IE 6.0 and Netscape 7.0.
Note that the reloading of the proxy configuration only appears to be necessary once per browser session.

The navigation isn't working. I click in the first text field to give the initial field focus. I then hit TAB and nothing happens. I have a key listener set up for the ENTER key, and this is also supposed to navigate to the next field via:
((JTextField)evt.getSource()).transferFocus();
To see if there was a problem with my build environment or threads in my application, I came up with the following dummy applet:
import java.awt.BorderLayout;
import javax.swing.BoxLayout;
import javax.swing.JApplet;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class TestApplet extends JApplet {
public void init() {
super.init();
public void start() {
JPanel myPanel = new JPanel();
myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS));
JTextField textField1 = new JTextField("Text Field 1");
myPanel.add(textField1);
JTextField textField2 = new JTextField("Text Field 2");
myPanel.add(textField2);
JTextField textField3 = new JTextField("Text Field 3");
myPanel.add(textField3);
getContentPane().add(BorderLayout.CENTER, myPanel);
public void stop() {
super.stop();
I then compiled this applet using the following:
javac TestApplet.java
I then put together the following HTML file:
<HTML>
<HEAD>
<TITLE>Test Applet</TITLE>
</HEAD>
<BODY MARGINWIDTH="0" MARGINHEIGHT="0" BGCOLOR="white">
<APPLET
CODE=TestApplet.class
WIDTH=635
HEIGHT=500
ALIGN=left
VSPACE=10
HSPACE=10
>
</APPLET>
</BODY>
</HTML>
The results are the same. I am not able to navigate using the TAB key until I bring up the Java console and then close it again. I would think that if this was a bug in 1.4.1_01, I would have seen it all over the forums. Any help would be greatly appreciated.

Java Plug-in linux installation problem

Hi!
I am new to this subject, but I want to comment that I have problems installating the java plugin into my netscape 7.0 for Linux. My platform is Red Hat Linux 7.3.
I have followed the instructions written in
http://java.sun.com/j2se/1.3/install-linux-sdk.html#install-pkg
but I still found that the plugin is not installed. (i.e when I open a web page that
requires java plugin I still see a window saying "this page contains information type
(application/java-vm) that can only be viewed with the appropiate Plug-in..")
and also as confirmation the web page:
http://wp.netscape.com/plugins/manager.html
checks that that it is not installed the plugin.
Would anyone please help me?

You posted a problem that would be answered better and faster in a Linux or Netscape forum.
You posted an installation question to "New to Java...", ignoring the fact that there is an "Installation" forum where you're more likely to get an answer.
You posted a question that has, in fact, been answered in these forums already. You didn't bother to use the "Search" function. Try "plug-in linux install", and check out the first page of results.
You posted a note, and waited FOUR WHOLE HOURS before whining that nobody's helping you. I'm amazed at your display of patience and understanding.
Hint: this is a volunteer forum, inhabited by random Java developers. People answer when and as they have the time or inclination. Nobody here is getting any kind of return from responding. Nobody here owes you ANY response, much less an immediate one.

Java Plug-in problems following installation of Oracle 9i

I have been experiencing repeatable problems with the Sun Java Plug-in following installation of Oracle 9i on our servers. Our installation of the Sun JDK 1.3.1_04 or higher seems to conflict with the Oracle installation. Following the install, navigating to any web page that includes an applet reference results in a plug-in error stating that it cannot locate the registry key HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in\1.3.1_01. The key does exist however for the installed version of the plug-in. ie [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in\1.3.1_07]. My only workaround to fix this is to add a new registry key 1.3.1_01 that contains the contents of the registry key for the installed plug-in (for example 1.3.1_07).

The Oracle installation only inlcludes the JRE, which AFAIK isn't referenced outside the ORACLE_HOME directory. The internal JVM couldn't be causing the conflict either. Might be an installer bug of some sort, but not one I have heard of.

Java Plug-In Problems !!

Hey you guys...I have the OS X 10.6.7 with the updated Java (update 4) and I cannot open any of my works' hospital website links. I keep getting this message
"The Java plug-in is not installed.
The required version: 1.6.0_07".
I've tried different links within the hospital's site and it's a no-go. I went on Mac's OS X Dev. Library to try to figure this out, found this link
http://developer.apple.com/library/mac/technotes/tn2002/tn2110.html#//apple_ref/ doc/uid/DTS10003202
but I don't understand anything that's its saying on how to identify what Java you have. I need to do continuing education for my job, and don't have time during work therefore I need to be able to do this @ home. Please help!!
P.S. It doesn't matter if I use Firefox or Safari, I still get the same message....
P.P.S. Please explain it in very simple terms I'm not very computer savy. Any help/tips would be much appreciated!!

Java Preferences should show:
Java SE 6 Apple Inc. 64-bit 1.6.0.24-b07-334
Java SE 6 Apple Inc. 32-bit 1.6.0.24-b07-334
Also, I was informed that " Runtime environment 5 and 6 are the more common versions required. " I should therefore contact the IT dept.
Lastly, it seems a number of people are having issues using Firefox 4 and running Java, having to reinstall the application a number of times..
Thanks for all your help guys!! Much appreciated!

Java plug in 1.4.1_04 the install package could not be opened

Hi .
I am trying to install java plug in 1.4.1 on a Windows XP client SP1 and I receive the following error.
Windows Installer
The installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid windows installer package.

If you used the online installer, try the offline installer. If you used the offline installer, you might have a damaged install file. Get a new copy and try again.
Read the Installation Instructions, if you haven't.

System.out Problem in Java Plug-in

I have the following problem, anyone can help me?
I have an application( Frame ) needed to be embedded in applet. The applecation has a lot of information output to console( by System.out ). When I embeded it into applet, these information will be output to Java Plug-in Console. In the beginning, there is no problem. But when the applet runs enough time, the output will be more and more, and the speed of the applet( in fact, the browser ) runs slower and slower.
I don't want to modify my application at all( it is impossible ). I wonder there is any good suggestion to this problem, I guess, maybe there is an interface to make the Java Plug-in clear its console buffer periodically.
Thanks in advance.

There is a good reason for this.... the console in the java plug-in is essentially a JTextArea... and continually adding text to it via System.out.println or the like will make it slower the longer it runs..... periodically clearing the console would be the only solution without modifying the code......
If you still need all that information you could redirect System.out to your own PrintStream and then instead of writing to the console little by little, you could save the original System.out (using something like:
PrintStream origSysOut=System.out;
) and then later on in your app reset System.out=myPrintStream or something.... then just write the myPrintStream data to origSysOut every now and then or something....
if you want a better example of this I've got a log facility class that I built based on this principal... it's also and easy way to capture stack traces into log files... and since you're just redirecting System.out or err it's easy to turn off the log file to use for debugging.... ok that's enough of a rant :)

This answer may be somewhat late, but just in case other have the same issues, I went to site listed below and it solved the problem. No need to reinstall CS5 product. I hope this works for you.

Java Plug-in 1.3.1_08 problem. IE stucks, running Applet, on setVisible met

Hello,
I have a problem, that appears in Plug-in 1.3.1_08 (1.4 is ok). The Microsoft Internet Explorer sucks, running my Applet.
It occurs, when AWT Frame uses method show().
In a correct situation (for example Java Plug-in 1.4), the applet appears in a separate window (not into IE). When the problem occurs, the Applet's window does not appear and the Internet Explorer (and Java console) are stuk in.
When I change the mehod to setVisible(true), the problem still exists.
In the both cases the Applet appears and works correctly for Java 1.4 and more.
Please help.

Have you check bugs.sun.com to see if this is a known issue? If it isn't there,
file a new bug.

After uninstalling and installing several times, Java plug-in is still undetected. Support suggested I open up the control panel and click update but there isn't such an option. The advance tab, there aren't any options to enable or disable plug-ins.

If you're running Java 7, then in System Preferences > Java > Java Control Panel in the Security tab there is a check box to enable Java in your browser. To check for update go to the Update tab.
