I m using 'linegraph' applet, the class file is placed in the web-archive. In <applet> code is class file name and codebase is root.
Any help will be highly appreciated.
Thanks & Regards

Looks like you are using an algorithm that is not supported by the jre.
Caused by: java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/ECB/PKCS1Padding
You might try and read this here on how to install the PKCS1 at the java client.
http://www.denison.edu/mathsci/mcurcsm2003/papers/JavaCrypto.pdf
http://www.bouncycastle.org/
Or you can create a certificate with keytool and convert to pkcs12 to be used with IIS (self signed)

Helpdesk Agent Needs help with JAVA applet not loading for HTTPS site

Sorry....I am posting here as I do not know where to start.

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?

I have download firefox 4 beta but now in some websites can not open. applet not load properly

I just download fire 4 beta on my windows vista. Can not open in some websites. the message applet not load properly please reload the page

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

Flash player not loading on http but works on https

I have an issue where flash player shows "movie not loading" on http pages but works fine on https.
I am using windows 7 64 bit, ie9 64 bit, i have tried it with the latest firefox and chrome and i still get the same issue.
This started with flash player 10.3, the 10.2 version did not have this problem and all subsequent versions have the same issue. i am currently using the 11.2 version of flash.
Example: Any flash video on youtube with the address beginning with HTTP, the video screen is black and when you right click you get movie not loading and the correct version of the flash player. If you change the header over to HTTPS the video works fine. this wouldnt be much of a problem except when going to any other website that has flash as its main element but does not have an HTTPS version, you cannot use the page or its features.
I have uninstalled and reinstalled several times, done a clean install, deleted all files and updated every area of my computer but this issue remains. I have read the forums here and done any suggestions listed to no avail and noticed many people have this type of problem. This issue has now been going on for almost 6 months. Can anyone help?
I may have posted this in the wrong forum and I appologize. If so can you please move it to the correct location?

I don't claim to know the solution to your problem, but in your situation I would try either or both administrator install methods: 1) Right-click the downloaded install file, choose "Run as Administrator" and install the software as usual. 2) Try using a different Windows account that you are positively certain has full administrator rights or the actual Administrator login name, install with that account.
Also, make sure you empty the browser cache before retrying the http pages. What about other browser settings, like security or privacy settings? Any add-ons or antivirus browser helper objects?
Do you only use Internet Explorer, or is this issue the same in Firefox, Opera, Chrome and Safari?
Good luck, hope you get the error fixed.

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,
Charu

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?!!!

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.

Like any good developer I have fixed my problem.
This blog gave me some clues and I think it comes down to how i have built and deployed it.

In the meantime to see it work in a browser i have opened it offline and just opened the html page that was in my dist folder created by netbeans.

Oh I found something: the message in the plugin....-log says

And the path should be http://www.unifr.ch/dokpe/about_dokpe/monomap.jar
So the /dokpe/ part is lost here.
The html has <BASE href="http://www.unifr.ch/dokpe/">
and the applet code is
<applet code='ch.unifr.dokpe.applet.monomap.MonoMap.class' height=550 width=700 codebase='../../about_dokpe/' archive='monomap.jar'>
Have to work on this.
Idea someone ?

Swf file not loading over Https(SSL) on Internet Explorer...

hi ,
I have a .swf file used in html file and i try to browse using "https(SSL)".it will loads fine in Firefox, but in Internet Explorer wont able to load. When right-clicking it says "movie not loaded".
even i googling for the same and i got below option but i am still not able to get flash on html page. it will working fine in Internet Explorer,FireFox etc when we use"http".
1) add headers like "Cache-Control: must-revalidate" or "Cache-Control: max-age=0" or "Cache-Control: no-store" etc
2) use CrossDomain.xml
we also able to load swf in https on Internet Explorer but for that we have to do below settings in Internet Explorer browser.
1) Go to Tools --> Click on Internet Option --> click on Advanced tab --> Now in security section checked mark on "Do not save encrypted pages to disk".
but above way is not a proper way to resolve the https issue
Thanks.

found this within the Adobe forums, seems to solve your issue.
I would make sure to use the crossdomain file as well.

Flash not loading using https

When I try loading the application using https it loads fine
in firefox but the .swf doesn't load up if I'm using IE.
I've found some documentation on this
http://kb.adobe.com/selfservice/viewContent.do?externalId=fdc7b5c&sliceId=2
I'm unable to change these settings so is there any other
ways around this?
Thanks

Object tag does not use DATA tag, that's only for EMBED tag
for none IE browser.
You need to actually specify param name="movie" follow by
value="moviename.swf"
Suggest you use flash PUBLISH option to generate proper html
file with full object
embed tag, than copy paste the complete set into you existing
document.

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

In the example where we have an issue we only see the following lines:

I deduce that

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.
Create a new profile for this user.

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?

Http sites do not load, but https sites do.

A couple of days ago (on May 23), I noticed that most websites would not load, but a few would.   Then I realized that it was only the https sites that loaded (and it was all of them), and that no http site would load at all.
I have no idea what caused this, as I was using the Internet like always on May 22, and I have never seen this problem before. I turned off the computer and went to bed. When I turned it on in the morning, I discovered the problem.
This occurrs in both Firefox and Safari. The problem just started on May 23, and I don't know what the cause was, or how to fix it.
There is another computer in the house that is on the same wireless network.   That computer has no problem (that one is a Mountain Lion).
I'm really frustrated by this issue, as I cannot currently access most websites on this computer.   Thank you.

Actually, I think the problem was caused by a conflict between AVG LinkScanner and the Sophos when Sophos updated last week.
I had had the AVGLinkScanner on my computer and didn't like it.   I couldn't find a way to delete it, so I disabled it a long time ago. I thought that it wouldn't affect my computer anymore, but apparently not.
I was looking through this forum yesterday and I came across a question by someone else who had both Sophos and AVG LinkScanner installed, and the question was similar in nature.   They said their problem was fixed by uninstalling the AVG LinkScanner, and they provided a link to another discussion on this forum that details how to uninstall it. So I uninstalled it (finally).
After uninstalling it, I went back into the Sophos settings and turned back on the items in web protetection. Then I tried http sites, and they still worked.   I also tried it this morning, after the computer was turned off and back on again, and the http sites still work.
So maybe some of the other people who had Internet connection problems at the same time as I did had a similar issue -- having both AVG LinkScanner (whether enabled or disabled) and Sophos anti-virus.
Either uninstalling AVG LinkScanner or turning off the web protection in Sophos solves the problem.    I think uninstalling AVG LinkScanner is better because it is an annoying program and, evidently, can still mess up your computer even when you have it disabled.
I'll look for the link to the uninstalling AVG LinkScanner discussion again so that people can easily find it.
