Java Applets - JRE 6 Update 18

Hi All,
I am working on a web application. Developed a web page using HTML <Applet> tag.
Web page is working fine on JRE 6 update 18 version.
Yesterday, my system gone through auto update of JRE 7 update 25. Today morning, i uninstalled JRE 7 update 25 and re-installed JRE 6 update 18.
Note : Before re-installation, have cleared all temp file, cache files, registry using CCCleaner.
Now, when i go to control panel, JRE 6 update 18 version is installed successfully. But the Applets on web page is not loading.
Error : "Object Doesn't Support this property or method".
Before auto update the same page was working fine with JRE 6 update 18 version, later its' not.
Kindly help.
Thanks.
S.Rajesh.

I also noticed the two different files, I downloaded them both and extracted the files to different directories.
The dates and file sizes match; I used Windiff to compare directories and they came up identical.
I guess a different method was used to create each of the installer .exes - I don't know why they are named differently though. From my testing the resultant extracted files are identical.

Java applet recompiling / updating applet problem?

I'm trying to teach myself how to program simple java applets. Anyway I have a weird problem....If I first create my applet with a background color of black and compile it, when I open my applet in internet explorer my bacground color is black. GREAT!
My problem is, is that if i change my background color to red and recompile my java code. Then close/reopen my applet with internet explorer the background is still black. My applet doesnt seem to be updating properly after the recompile.
I have This problem as well if I try to add shapes after the original compile, when I recompile and reopen my applet, my applet is still showing only whats there after the original compile. Any idea what going on?

Sir,
Debugging applets in a browser is a real pain because it isn't reloading you class. You would need to shutdown your browser and restart it to see the changes.
Thankfully there is an easier way.. look at appletviewer.
Sincerely,
Slappy

My Upgrading Java Applets Cache won't finish

I had to reinstall Java 6.0 and each time I try to run something requiring Java, it doesn't load. All I get is a box stating Upgrading Java Applets Chache, it runs about half way and then quits. I am getting very frustrated after working on this for 2 days.
It says "Please wait while your stored Java Applets are updated for Java SE 6". Runs for about 20 secs and then stops and the box disappears. Does anybody have any suggestions? I am not very computer savvy so please explain in simple terms.
Thanks

Hi
I had the exact same problem. took me days to find the solution, hope it works for you.
Click on the START button bottom left on the screen, Then look for the CONTROL PANEL button and click, (this should bring up lots of icons for programmes) on some computers its under themes and sttings I think. Click on the JAVA icon this brings up a CONTROL PANEL. Click on SETTINGS at the bottom, then click DELETE FILES. (this took a while to complete on my computer) Just to make sure after you've done this bring up the JAVA CONTROL PANEL again but this time click on ADVANCED. Then at the bottom theres is Miscellaneous, click on this and there should be JAVA QUICK STARTER with a box ticked next to it, Click on the tick and get rid of it then click on OK..
Try a website that uses Java. the cache box might appear again but just hit cancel. When I tried this i was able to use Java again.
Hope it works

Java applet failures after updating to Java 6 Update 19

Hi,
I'm currently experiencing a failure of unsigned Java applets after upgrading to JRE/Plugin 1.6.0_19. The problem with the update has been narrowed down to an interim fix for a TLS/SSL Man-in-the-Middle attack (see http://java.sun.com/javase/javaseforbusiness/docs/TLSReadme.html). This fix intentionally fails attempted renegotiations.
The environment consists of Windows XP PCs running IE6/7 and JRE 1.6.0_19 as clients connecting to a website using SSL connections and SmartCard(PKI) authentication.
Previously, clicking a link on the website produced a new window to an URL with some HTML that uses an <APPLET> tag to open a Java applet. Prior to the applet loading, a Java "Request Authentication" dialog would pop up to allow selection of a certificate to be used for authentication from the browser keystore.
Now, no such dialog displays. And, depending on client and chosen applet, these responses are observed:
(1) complete failure of the applet to load with "java.lang.ClassNotFoundException" and "javax.net.ssl.SSLException: HelloRequest followed by an unexpected handshake message" errors in the console;
(2) the applet loads but is unable to read its data files with "java.io.IOException" and "javax.net.ssl.SSLException: HelloRequest followed by an unexpected handshake message" errors in the console.
Overriding the interim fix with "-Dsun.security.ssl.allowUnsafeRenegotiation=true" results in a return to normal operation, but our security team does not deem this override an acceptable solution.
Any ideas?
Eric

Thanks for the detailed log.
Your server requested a renegotiation, and as renegotiation is unsafe, the client refused to renegotiate the connection. That's the expected behavior.
However, it seems strange that the server send a incorrect block of data immediately following the renegotiation request. From the bytes, I don't known what was the data the server sent following the handshake message. It would be of help if you could load your another log with the debug enabled (javax.net.debug=all)and unsafe renegotiation enabled(sun.security.ssl.allowUnsafeRenegotiation=true).

Java Applet 6 crashes after Apple update in Firefox 8

After my update in Apple a day ago, my Java (6.0version) and Firefox 8 do not mix. I can't open a second window without Firefox crashing.
I have also "tested" my Java on the Java website and it says Java's working, then when I hit the back button, it crashes again.
I know other Mac users are having this issue using the OS X v.10.6.8. (Google it)
Now, Apple points the finger at Firefox, who all know about this "bug" and they in return accuse Apple of the Java release not working with their new Firefox. I am stuck in the middle trying to figure out a way to get this resolved.
Can someone please help? Who's fault is this? I would have not updated these two (which were working wonderfully before the upgrade!) So frustrating! I have included how to test the crash error:
Steps to reproduce:
This happens with Firefox 8.0 and Mac OS X 10.6.8 and java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-10M3527).
Visit
http://java.com/en/download/testjava.jsp
wait for the java applet to load and display the JRE info. Close the tab and firefox crashes.
I have also included a copy of my console file list messages in the diagnostic section re: Firefox. Hope this helps, thank you to all who reply.

Okay, funny how I don't know a whole lot about computers but I did quite a lot of research on this and found the fix for this Java (6.0) problem.
FIrefox said it probably was the Apple release of the new Java that conflicted with it's newest release, though I had to read about it on their bugzilla.mozilla.org website to find out more.
Firefox released a fix for the 8.0 (now version 8.0.1) to help with Java and Roboform platform on their FTP Server.
You can't do the update through "about Firefox" on your pull down tabs and click "check for updates" because that won't work.
You can go to this link for an explanation and download link:
http://browserfame.com/309/firefox-801-browser-crash-fix-roboform-apple-java-upd ate-mac-osx
A window with files will pop up. Choose your OS....Mac-for OSX users, then more files come on the next screen, Choose - "en-US" for US english, if that is your Firefox program version.
I hope this helps anybody who had this frustrating problem. I know Apple is committed to Safari browser but they wouldn't suggest or even give an probable answer about this and I had to scramble scratching my head to find the answer myself....sad.

Java program not updating in correct sequence in applet

Greetings,
I have a java program with interactive graphic components. After completely writing the program, I create two shells ( or handle): an application shell with JFrame and an applet shell with JApplet. The application version of the program works fine. But the applet version skips some (middle) steps in the painting process when responding to user inputs.
Does anyone have any ideas as to what's going on?
I am not able to embed code snippets because my Internet has not being working and am finger typing this on my cellphone.
Thanks for any help.

My cable person won't come before Monday so I am struggling for now. Thanks for the replies, though.
More info:
1) both shells are extremely basic. They both simply add the drawing panel like so:
DrawingPane drawingPanel = new DrawingPanel();
add(drawingPanel);//frame.add for application
the application uses statc main; the applet uses init. Nothing more.
2) the program paints the hands and fingers of a stick figure red or green dependring on which foot of the figure is clicked.
3) the application version works completely
4) the applet version updates the right hand the first time; but not on subsequent clicks. More mysteriously, although it skips the hand, it still go on to update the fingers.
5) No I don't know about event threads yet.
Thanks.

I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Is Apple aware of this problem? No longer supported?

My web page uses a Java Applet to allow my visitors to replay chess games; the Chess Viewer Deluxe applet was written by Nikolai Pilafov some time ago and has been working properly for some time (until recently). I don't monitor this part of my site regularly so I am not sure when it began to fail. On his web site [http://chesstuff.blogspot.com/2008/11/chess-viewer-deluxe.html] he has a link to check LiveConnect object functionality (which fails for OBJECT tags). His recommendation is to "seek platform specific support which might be available from the JRE developers for your platform".
I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Until I checked the LiveConnect object functionality, I was unable to identify the source of the console error messages. This does seem to be the smoking gun.
Is Apple aware of this problem? Are these classes no longer supported? Has anyone else had this problem? You can attempt to recreate the problem locally by going to my web page: http://donsmallidge.com/DonSmallidgeChess.html
Thanks in advance for any help you can provide!

I just went up to check the LiveConnect object functionality page AND IT WORKED THIS TIME! I must confess, this is very mysterious. I will do some more checking and reply here if I can determine why it is working now (and more importantly, why it didn't work before).

Update 10.6.8 and the combo pack v1.1 but java applets still not working

Checked all the java settings in the browsers and in java preferences and they are correct.
Tried both Firefox 5.0.1 and Safari 5.0.5 (6533.21.1) neither worked. Runing Java SE 6 (both 64 and 32 bit) version 1.6.0_26-b03-384
Even tried to uncheck and disable then re-enable java and restart, cleared cache, etc. Tried it all.
Thought the combo update version 1.1 would help. Nope didn't do anything.
Wanted to upgrade the OS today, so installed all current updates. Never upgraded the OS because I want to have this fixed first.
I don't use time machine since I don't store my folder system locally, so I can't revert back before the OS updates. Don't want to reinstall the OS, actually can't even remember where I put it. Any suggestions? When is the issue going to be fixed?
Checked around on a dozen or so message boards, seems like this is happen quite a bit. Even heard upgrading to the new OS has the same issue.
So, fustrated. Need the java applet working asap.

None of those things you mentioned were what I suggested.
I'm guessing the "ctrl click in printer preferences" means you Reset the Printing System?
If so, that is what I would have suggested if deleting it by selecting the ( - ) button and then adding it with the ( + ) button.
But, if HP has a fix, it likely needs to update its drivers.

Does the Safari5.1 in Windows7 use its own java plug-in instead of SUN's?

So I can update my Oracle Java Applet Plug-in to Development Kit 7, Update 65, can you link me to the correct Oracle download page from your Plugin Update page?

When I periodically accessed your Plugin Check and Updates web page in the past, I really appreciated you connecting me to the correct Plugin Updates vendor web page when I clicked on your red Update Now button. This time, however, your Java Applet Plug-in "Update Now" button linked me to the Oracle Java "7u65 Updates Release Notes" instead of the usual download page. It seems rather unexpected for me, or any other conscientious user for that matter, to search the appropriate "JDK 7U65" file download from the Oracle website.
Thank you,

This is getting way too complicated for normal peop.
First: the "Update Plugin" does not work, it goes to a page with all sort of computer jargon but no "Update button" anywhere.
Second: this forum jscher2000 gives a good solution, but I downloaded the incorrect java update, because my computer is 64 bit. how am I supposed to know my browser is what it refers to and that FF is 32 bit.....???$%^&*()??
Third: some of those "critical update" software are not even on my computer....well at least I don't think it is, I search for "shockwave" and did not find it.
I love Moz FF but the updating is starting to get out of control. why give us (computer idiot) an auto recommendation update not tailored to our computer? Perhaps in big letters at the top there should be an explanation "this is general suggestion these plugin needs updating, not to tailored with your computer, do your own research"
and/or add info I need to know like the 32 bit thing, took me forever to download the 64bit update for JAVA and it was the wrong one.
Now I am just afraid to update anything for FF because it is too darn confusing.

Problem running Java applets since Java update 2 (1.6.0_20)

Hi,
Since I upgraded to Java update 2, Java applets started having problems. The most noticeable ones are:
Non-modal windows appear behing the browser Window (tested Safari 4, 5, Chrome 5).
Double buffering not working as usual (slower, white boxes appear when dragging a window, etc.)
Slower rendering in general
The same applications run perfectly using Java Web Start. And they used to work very well also in Java update 1.
The application can be tested here (press ok if a login prompt appears):
Java applet: http://jmap3.k2geospatial.com/montreal_applet/
Java Web Start: http://jmap3.k2geospatial.com/montreal_jws/dockingClient.jnlp
Our applications running in applets use the new plug-in 2 with JNLP files.
Notice the Java startup splash (the animated sun-like logo) is not moving as smoothly as usual. It is very jerky now.
Are these problems known by anyone?
How can I downgrade Java to previous version?
sorry I cross-posted this in Unix forum also. I think it is better here.
Thank you,

Since the last Java update on mac, all my OpenGL applets stop working and now just shows a white screen on Chrome, Firefox and Opera. They was working well on all browsers (Safari/WebKit,Chrome,Firefox,Opera) just before the update.
The trouble maker seem to be the java plugin 2 and the new offscreen rendering pipeline, as reported by jrhaddad with the disucssion linked to the different Java/OpenGL community forums.
This is a huge regression for me, and I think for all hobbies/ independent developers and all companies who are doing some Java/OpenGL develoment. All our work just stop working since this update.
If would really want to know from Apple if they are working on this problem and/or how this can be solved.
Should this be fixed by Apple with a new java update, or should the various browsers must upgrade their applet support plugins according to the new java plugin 2 changes ?
Best Regards,
Jérôme

I have a Mac running OS X 10.6.8 and have installed all updates and disabled Java Applets. Do I need to put virus protection on this computer and, if so, any recommendations?

I have a Mac running OS X 10.6.8 and have installed all updates and have disabled Java Applets. Do I need to install antivirus software and, if so, do you have a recommendation on what works best.

Mac OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
The most effective defense against malware is your own intelligence. All known malware that affects a fully-updated installation of Mac OS X 10.6 or later takes the form of trojans, which can only work if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown site, merely in order to use the site, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim.
“Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Disable Java (not JavaScript) in your web browser(s). Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in Mac OS X 10.5.8 or earlier, because Java in those versions has bugs that make it unsafe to use on the Internet. Those bugs will probably never be fixed, because those older operating systems are no longer being maintained by Apple. Migrate to a newer version of the Mac OS as soon as you can.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use ClamXav — nothing else.

No sound in java applets in 32bit firefox with bin32-jre plugin.

I got sound in flash, but not in java applets. Is this a known issue? Any workarounds?

I should probably make a wiki article (or ad to the Java wiki article) about this, since it seems to come up quite often (especially on Ubuntu forums, actually). The only good solution I've found is to use Pulseaudio, and rename the java executable to java.bin, and make a script called java in the same folder, and put this in the script:
#!/bin/sh
padsp /opt/java/jre/bin/java.bin "$@"
By the way, the path to the java executable is /opt/java/jre/bin/ I've tried using the same method with plain ALSA by using aoss, and it works sorta, but it causes random crashes of Java, so that's a no go, have to use Pulse.

Changes in security from 7 update 45 to 7 update 51 and problems with Java applet

Hello,
After the update (from 7 update 45) to version 7 update 51 we've gotten some problems with a Java Applet as it won't run.
When changing security settings to "medium" it works, but it would not run under the default "high" setting. This lead me to update the manifest file as follows:
Manifest-Version: 1.0
Trusted-Only: true
Application-Name: MyApplet
Permissions: all-permissions
Caller-Allowable-Codebase: www.MySite.com
In addition to this, I added the <param> tag in the HTML page.
<applet name="MyApplet" code="MyApplet" archive="MyApplet.jar">
<param name="permissions" value="all-permissions" />
</applet>
The applet is digitally signed with a certificated issued by Verisign.
It now runs on my system. But I noticed that it also runs if I switch the security setting back to "high", which doesn't make any sense to me.
I've tried another computer and to the same thing there. Would not run. I switched to "medium" and and the applet worked. Switched back to "high" and it still works.
I've tried this in both Google Chorme and Internet Explorer 11.
On a third computer it won't run at all, getting a different error message than on the other two, but still related to permissions/security.
The console log message is:
"liveconnect: Security Exception: JavaScript from http://MySite.comn/MyPage.html attempted to access a resource it has no rights to."
Any ideas what I'm missing or what I need to change to get this beast to run everywhere.

I tried changing the Caller-Allowable-Codebase to not include "www." and it started giving the the same error message as for the third machine in the test.
So, I changed Caller-Allowable-Codebase to "*" which made it work on all machines.
I don't quite understand why it acts differently on different machines, if it's ok with www.MySite.com on one of the the machines, it should be OK on all no?
I don't see a problem with letting it be "*" but it would be nice to understand what's going on.

Run Java Applet w/o installing JRE

Hi all,
I'm wondering what would allow the client to run the java applet w/o having to install the JRE? I have seen it done but not sure how they did it. I wrote a simple java applet (not even JApplet) and IE said "class not found" until I installed the JRE on that machine. Any tips? Thanks so much in advance.

Looking at your sample, I would say this could run in the old JVM.
You might simply be having problems with the JVM finding your classes - I believe this is specified in the HTML (but its been too long for me to give details).
Also, your Internet Explorer could be looking for a plug-in JVM (I believe this is specified in Tools-Internet Options-Advance menu).
And finally, Windows (XP?) may not have this JVM built in anymore - never could figure out the outcome of the law suite.
Hopefully someone with more recent Applet experience will chime in.
