Your More system details list doesn't show the Java plugin as installed.
Update the [[Java]] plugin to the latest version.

Signed Applet not loading on Mac OS X if using HTTPS protocol
Hi All,
I need to open a trusted applet on Mac OS 10.2. The applet works fine if using HTTP protocol. But if the protocol used is HTTPS the the applet does not loads and "javax.net.ssl.SSLException - untrusted server cert chain" exception comes on the console.
The error comes for both - Verisign and javakey - signed applet.
On seaching for possible solution on the net, i came across following link: http://www.macosxhints.com/article.php?story=20020525101202503&query=Workaround+for+secure+Java+applet+problems
It says that this is Mac's known bug and gives the workaround as:
1. Access the problematic site with Internet Explorer on Windows. Click on the padlock item and export the certificate to a file.
2. Copy the certificate to your Mac.
3. Use the command
sudo keytool -import -trustcacerts -keystore /Library/Java/Home/lib/security/cacerts -file mycert.cer
to import the certificate file to your keystore (substitute mycert.cer with the name of the file containing the certificate). The keystore is password protected - the default password is "changeit".
4. Restart your browser
But the client cannot be asked to do all this to run the applet.
Is this problem being solved by Mac in their java implementation or is there any other possible solution?
Thanx in advance.
Regards,
CharuI am experiencing the same problem - I notice it does not happen on OS9.2 using IE but appears a problem on all browsers on OSX
Apple gave me the following reply.....
Re: Bug ID# 3268633: cannot load applet class under https connection
Hello Andrew,
Thank you for bringing this problem to our attention. We have received feedback
from engineering on your
reported issue.
Please know that to get Java to recognize the certificate you will need to do
one of two things, depending
on which VM you are using. Since you want it to work with Internet Explorer, we
will assume Java 1.3.1.
In Java 1.3.1 you'll need to add the certificate to
/Library/Java/Home/lib/security/cacerts using
/usr/bin/keytool to import the certificate into the certificate database.
In Java 1.4.1 you should be able to just add the certificate to the keychain
using certtool. For more
details on how to do this, please refer to the information found at
<http://java.sun.com/j2se/1.4.1/docs/tooldocs/solaris/keytool.html>. After
doing so, if you should require
further help from Apple in resolving this issue, we recommend that you request
assistance from Developer
Technical Support. This must be done by filing a Technical Support Incident.
So I am supposed to tell every Mac user to do the above am I?!!! -

Applet not loading in some environments
Hi,
We have an applet that works for 99% of our users but for one user the applet does not start. Are there any specific proxy / browser settings that could prevent the applet from loading properly? Outputs from the java console for the working users show the following lines:
basic: Applet loaded.
basic: Applet resized and added to parent container
basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt 116394 us, pluginInit dt 399250 us, TotalTime: 515644 us
basic: Applet initialized
basic: Removed progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@1abab88
basic: Applet made visible
basic: Starting applet
basic: completed perf rollup
Start Method
basic: Applet started
basic: Told clients applet is started
In the example where we have an issue we only see the following lines:
basic: Loading applet ...
basic: Initializing applet ...
basic: Starting applet ...
basic: completed perf rollup
basic: Stopping applet ...
basic: Removed progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@b51404
basic: Destroying applet ...
basic: Disposing applet ...
basic: Joining applet thread ...

basic: Caching classloader: sun.plugin.ClassLoaderInfo@a89ce3
basic: Current classloader cache size: 1
basic: Done ...
basic: Quiting applet ...
It seems like for some reason its attempting to start but then instantatly stops .... we don't see any exceptions in console.

Another user has tried on a different machine on the same network with the same results.A different user on a different machine is not likely to tell us anything.
All machines sit behind a proxy server and browser settings are managed centrally.So, the profile for this user may be corrupt.

Hello - would love any help. I cannot get into admin applets on my windows 7 installation. i was able to access through another computer, but now i can't with that. when i get into the admin page (with chrome, firefox, or MS explorer), the java icons just keep loading. when i try through the OS, it prompts for username and password and they are incorrect. (i am sure they are correct). with safari, i get the error "The Java Runtime Environment cannot be loaded from <C:\PROGRA~2\oracle\JavaFX2.1 Runtime\bin\server\jvm.dll>. I tried a full text search for parts of this path and can not find where it is set. does anyone know how to change the JRE path?
thanks!
TerriTake a look at those threads: Problem with Admin Applets ! Admin Applets not working
Usually, it is a Java version. Sometimes, using a different browser also helps (I used to have issues with Mozilla Firefox, but in Chrome it worked fine). -
Yahoo chess Applet not loading in Firefox
When I am at Yahoo Games, the pop up window for Chess opens, but never loads. I tried it in IE and it works fine - so the problem comes down to Firefox.
When I click on a games room - and window pops up and asks to punch in a code (to avoid spam). This pop up works fine, I then proceed to punch in the code and then I go to another pop up window where the Chess Game normally loads. Only now it doesn't load at all.
it says to... Wait 3 minutes for applet to load... Click '''here''' if applet fails to load. Normally I've never had to wait 3 minutes before (ever) - now, even if I wait, it still doesn't load.
Any help would be greatly appreciated.Still not working in Firefox! I can play fine in IE. I have tried everything from uninstalling java and reinstalling, clearing cache, etc... nothing works! Is there not anyone at Firefox that knows of a solution?

Components and applet not loading when running the application using JVM1.3
I have my UI written in JavaScript.When I click a button,it opens a window showing the different components(images) and an applet containing a tree structure.The applet code is written in java
This is working fine and the applet is loading properly when I use JVM1.4. But there is a problem when I use JVM1.3.1_09.The images appear broken and the applet doesnot load.(When I click on one of the broken images,the images appear correctly but the applet still doesn't load)
Can anyone tell me what could be the reason behind this behavior??

joseph,
thanks for the follow up. i still was not able to load the applet from
the web-inf directory so i just jarred up the applet, stuck the jar
file in the jsp directory, and added the archive attribute to the
jsp:plugin element. everything loads and works fine. maybe i'll
revisit loading applets from the web-inf directory later. thanks
again.

Java Applet not loading in Safari
Hi folks.
I just noticed a problem with Safari on my Macbook Pro. I'm trying to use Keepvid to download videos from Youtube but it no longer works.
I load then link into Keepvid and then get the message "Java Applet Loading..". Except that it remains stuck like this forever and it does not work at all.
How to fix this please?I have exactly the same problem.

I'm also using zonealarm as a firewall.
any Ideas? -
I am running an FTP server "Rumpus" and generally it works very well.
It does FTP and FTP via HTTP. We use it as an internal FTP server within our company.
However, there is a drag and drop feature that has stopped working on most clients that are connecting using Firefox and Safari.
The problem seems to be that the drag and drop function is a Java applet that requires the client to accept a digital signature, and on almost all machines the window prompting users to accept the certificate/signature never pops up.
The drag and drop feature works on a Windows 2003 server box, and one Mac. The other 35 macs we run all fail to load the applet. The clients connecting are a mix of 10.5.8 and 10.6.3 machines. There is no proxy server, all system updates have been done. Occasionally if I run "cocktail" and clean caches it might work once before crashing Safari or Firefox. I tried Firebug in Firefox but it does not catch anything, no messages in Console either. Under the Java preferences pane, what versions of Java need to be turned on? Any history of other things that might conflict with Java? Any suggestions...Make sure the Java version selected is current:
http://support.apple.com/kb/TS3489
Mac OS X has its own built-in FTP server, which is documented here:
http://www.dummies.com/how-to/computers-software/macs-os-x/Mac-OS-X-Snow-Leopard .html?sort=POPULAR&page=3
And Leopard has one as well:
http://www.ehow.com/how4674062set-server-mac-os-leopard.html
Finally, if your problem is connecting to another FTP server, SFTP is well done by Fugu for the Mac:
http://rsug.itd.umich.edu/software/fugu/
And regular passive ftp is easy with the light mode of
http://www.rbrowser.com/ 's RBrowser.
Both work well with Leopard & Snow Leopard.
Java is great when it works, but it can get really bogged down if it is a Java client on a PC that requires ActiveX PC plugins. While any Intel Mac can run Windows to act on ActiveX, and possibly WINE, ActiveX based Java is very insecure. I recommend steering away from non-Mac based Java apps wherever possible. -

basic: Exception: java.lang.ClassNotFoundException: a.classIt seems as though it's trying to load the applet from the actual directory, instead of the JAR. Any ideas on why this is happening? Thanks in advance for your help.
Also, the applet is located at http://io9labs.com/poke/I'm using Mozilla Firefox 3.0.1 on Windows XP with SP2. I tried running it with IE7 and it gives me the same exact problem. It can't be my browser because it loads JAR'ed applets on any other webpage just fine.
I tried it with a non-obfuscated JAR, and it STILL gives me the same error. Do you have any ideas as to why it would choose to ignore the archive attribute?
EDIT: I think it might be because I signed it improperly, lemme try that.
EDIT2: Nope, still doesnt work
EDIT3: Problem solved, it was because the JAR needed a unique name, and i already had a jar of the same name in my cache.
