Please let me know on how to rectify this problem. Thanks,

I 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?!!!

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.

Charu

User rejected the cab - signed applet doesnt load

Hi,
I have signed my cab file and IE requests for permissons when I access it. If I deny the permissions, my signed applet doesnt load. Is there any way to make the applet load even if I dont grant the permissions. I expect only the 'out-of-the-sandbox' operations to fail - not the entire applet!
Thanks

I found a solution to this. Details on my blog at:

Security problem when signed applet dynamically load plugins

Hi!
I have one problem : "security problem when signed applet dynamically load plugins"
This is the scenario:
the main program [app.jar]
. contain applet and shared library (interface & implement of common class)
. it is signed and run normally on browser
. it can draw image loaded from other URL [ex] http://bp1.blogger.com/image.jpg
. the image loader is in the shared library
. dynamically load amazon.jar through URLClassLoader and reflection
the plugin [amazon.jar]
. search amazon product [ex] Harry Potter book
. draw image on applet
. use image loader from shared library, BUT CANNOT LOAD IMAGE
The question: "Why it cannot load image, because the image loader is in the shared library which has been signed and working?" I tried to sign the amazon.jar too, but it did not work.
Your reply would be very helpful. Thank you.
Sovann

Signed applet not working in firefox - java.security.AccessControlException

Hello,
I have a signed applet that works fine in IE 7 but in Firefox I'm getting this exception in the java console:
java.security.AccessControlException: access denied (java.net.SocketPermission myhost.com resolve)
I already tried to run the applet with different JRE versions in Firefox with the same result: 1.6.0_01, 1.6.0_02, 1.6.0_03, 1.6.0_05
I'll appreciate your help.

thanx 4 replying
using the browser to view Applet is not recomended that is because if u change the the source-code and recompile the applet then run it using the broswer it will run the old-version
Also i've found the solution here

Signed applet not working with weblogic 5.1

I have a problem with a signed applet. The applet is signed correctly
and it starts up the dynamic trust management console in java plugin
1.3.1_02 when accessed locally with the browser. But when trying to
access the applet through weblogic (5.1) the dynamic trust management
doesn't popup, as if the applet is not recognized as signed. In the
weblogic policy file in WLS I have set permissions to include the
applet class (AllPermission given to codeBase https://-, and file:/-
to be sure that it's not the problem).
I have tryed to run it under both http and https. I'm not making an
rmi connection back to WL. I'm simply trying to write on the local
file system with the applet.
The error received in the javaconsole is java.lang.SecurityException:

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: 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.
Relatively new to applets so any advice would be appreciated

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.

11g admin applets not loading

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!
Terri

Take 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?

I am repeating the question that RHM submitted...has anyone found a solution to this issue...Applet com.pogo.client.jvmtest.applet started. I was not having a problem and then out of no where on Sept. 13 my game rooms failed to load and this message started appearing. I have done everything asked of me to clear files both Internet and Java, to uninstall, re-install, etc...nothing works. Does anyone have an answer for a very non technical user?

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??
My sys config: win2k-SP4, IE5.0-SP4

If you are using SDK 1.4 for compilation,
recompile your classes with the option -target 1.1
javac -target 1.1 MyClass.java

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.
