A bug of java plugin

If you uncheck cache enabled option on "Java Applet Cache Viewer" from Java Console, you will find JavaPlugin not sending "Accept-Encoding" HTTP head to web server any more. So the plugin cannot load *.jar.pack.gz from server.
I think this is a bug. Do you think so?
I found this problem under JRE 1.5.06 and IE/Firefox enviroment.
Pls send any question about this to [email protected] Thanks.

Yes, it looks like a bug in Java 5 (1.5.0_xx).
The problem does not exists in Java 6 though. Have you tried Java 6 ?
Also, in the upcoming new 6u10 consumer release, there is a new feature that allows you to use pack200 compressed JAR with java web start or java plugin, without any server side requirements (you don't need to run a servlet anymore!):

You can download 6u10 early access builds here: http://download.java.net/jdk6/binaries/

Memory Leak Java Plugin with Swing Applet

Hi
I experience the following problem and desperately need help on this. The Java Plugin (I use Version 1.3.1_02) seems to have a problem in printing Swing Applets.
The problem can easily be reproduced (at least with NT):
1) Start Internet Explorer or Netscape (I used 5.5/4.07)
2) Launch the following demo swing applet
http://java.sun.com/products/plugin/1.3.1_01a/demos/jfc/SwingSet2/SwingSet2Plugin.html
3) Print the applet and observe (using task manager) the memory used by the browser process (the memory used by the process will increase every time you hit the print button but never decrease unless you shut down the browser)
4) Print a couple of times (you may want to pause your print queue) and you will be able to crash your computer
This seems to be the same bug reported with 4638742. However it says "in progress" for quite some time and I was wondering if some genious might know a work around for this.
Cheers

Java plugin crashes when creating a new sun.security.pkcs11.SunPKCS11 object

Hi,
I have created an applet which signs pdf files and works fine.
Applet is used in a website that needs client authentication with the same smart card wich is used to sign the documents.
The java plugin crashes at this line of code. The message showed - The java applet plugin has failed
sunpkcs11 = new sun.security.pkcs11.SunPKCS11(pkcs11);
I think it crashes because the pkcs11 module is still used, the light of the smart card reader is not blinking is a fixed light.
I haven't got an error log because the java plugin crashes. Only shows the log lines before that line of code.
Later the sunpkcs11 provider is added if the smarcard is unplugged and java plugin don't crashes.
Security.addProvider(sunpkcs11);
If I unplug the smart card after client authentication and before sign a document, the java plugin don't crashes and later, the provider is added, and the document is signed and the light of the smart card reader is blinking before signing.
Firefox 27 version.
Java Standar Edition version 7 update 51 compilation 1.7.0_51-b13
I'm using mac os x v10.9 64 bits system
I have seen:
http://bugs.java.com/view_bug.do?bug_id=8026833
I have tested the same applet with firefox, in windows 7, windows 8, ubuntu 13.10 and fedora 19, and works and signs documents after client authentication.
when applet is loaded in windows is not using pkcs11. But I haven't got the same problem.
But in mac os x v10.8 and v10.9 java plugin crashes.
Is there a way to disconnect programatically the pkcs11 module or any other solution?
I'm not sure why the java plugin crashes. Has got any relationship with the bug 8026833?
Any suggestion?.
Thank you.

Hi,
According to your post, my understanding is that you had Errors TF30162 and TF250025 when creating a New Team Project in TFS2012 with Sharepoint Site on Visual Studio.
The Errors TF30162 seemed that the reports for TFS could not be uploaded due a permission problem. The fix was really easy.
Go to your team foundation server
Open the administration console.
Click on Reporting
Click on Edit
Click on Reports Tab
Enter the credential for the Reports
Save
Click on Start Jobs
In addtion, the problem may be due to the caching done by Team Explorer in Visual Studio. Exiting the copy of VS on the client and reloading it will fix the problem as the updated team process settings will cached locally.
To resolve the Errors TF250025, you will need to register a new internal URL for the SharePoint site using Alternate Access Mappings.
Here are two great blogs for you to take a look at:
http://blogbaris.blogspot.in/2012_08_01_archive.html

If still no help, for quick and accurate answers to your questions, it is recommended that you initial a new thread in Visual Studio Team Foundation Server forums.

Java plugin support discontinued

According to some techinical articles released by Apple, Java update 10 for OSX 10.5 no longer supports the java plugin. As a result, java will no longer work with Firefox or Chrome unless users update to OSX 10.6. Although there may be valid technical reasons for doing this, it is really inexcusable that this was not CLEARLY communicated to users in plain and simple language before the update was uploaded. Here is part of the explanation released on one of Apple's mailing lists (but not the general public):
"Firefox and Chrome users are currently unsupported on PPC since the current versions of those browsers are = Intel-only. Anyone with an Intel Mac should upgrade to Mac OS X 10.6 Snow Leopard to continue to receive any updates at all.
Plugin2 in it's current state was barely usable when run under J2SE 5.0 anyway, so in the end, anyone who was relying on applets on Leopard was probably already using Safari anyway."
I think it's pretty arrogant that Apple assumes no one using Leopard was using FF or Chrome to browse sites supporting java and to not even bother informing them that support was going to be discontinued.
Just saying....

The problem is summarized and a workaround is given in https://bugzilla.mozilla.org/show_bug.cgi?id=668639 (comments 4 and 8):
Quote:
This bug is entirely Apple's fault. For some reason Update 10 removes
the JavaPlugin2_NPAPI.plugin soft link from /Library/Internet
Plugin-Ins/ (and also the ability, in the Java Preferences utility, to
choose whether to run applets "in their own process" or "within the
browser process").
JavaPlugin2_NPAPI.plugin is still present on the system, where the
Java Embedding Plugin can still find it. So Java still works in FF
3.6.18 and earlier. And so this bug is relatively easy for a somewhat
sophisticated user to work around:
Just do the following at a Terminal prompt. For it to work, you'll
need to be logged in using an account with administrator privileges.
$ cd "/Library/Internet Plug-Ins/"
$ sudo ln -s /System/Library/Java/Support/Deploy.bundle/Contents/Resources/JavaPlugin2_NPAPI .plugin

Mouse navigation don't work with Java Plugin.

I'm using forms 10g (10.1.2.0.2) with a Java Plugin 1.5.09.
The mouse navigation limit seems to be broken and I can't use the mouse to navigate.
The same form using jinit works fine.
Is there any reason ? Is it a bug ? Any workaround ?
Tks
Tullio

I'm having the same problem
Trying to switch from Jinitiator to JRE 1.5.0_12
Forms 10.1.2.0.3
All the forms come up, but I cannot select a field with the mouse. When I click in a field, the cursor moves momentarily to the new field, but bounces back to the prior field as soon as I release the mouse button. This seems to be happening in every form.
Can anyone help?

Weird Exception reported by Java Plugin

Hi all,
I am working on pure swing based applet project. We are using the latest Java plugin - Java(TM) Plug-in: Version 1.4.1_01.
Everything seems to work fine, but, frequently the following exception is reported in the Plugin console. Although it has not noticeably affected my project, I wonder what is happening and why it is reported. If anyone can throw some light, I will be glad to hear.
This exception occurs on both Windows 98 and Windows 2000 professional systems.

How do I get different and older versions of java plugin to work

I want to use firefox at my work, my company uses a program that uses java. But the programmers at my company aren't really good and when they check for the java plugin they check for the specific jre-6u21 instead of the generic with 6uXX. Sometimes I have to use another version of the program that requieres Version=1,4,2,06. They work fine with iexplorer.
If I update to the current version (update 24) Firefox can't find the plugin. Explorer just gives a warning that you might be missing important security updates.
Can Firefox give a warning or run with the latest version instead of looking for the missing plugins?

This is what Oracle has to say about the problem: [http://www.java.com/en/download/faq/other_jreversions.xml Download older versions of Java]
If you install an older version in Firefox it will be listed in Tools | Add-ons | Plugins and you can disable it there. But as Oracle mentions, using older versions potentially exposes your system to attack such as the one mentioned here: [http://www.h-online.com/open/news/item/Java-SE-6-Update-24-fixes-floating-point-bug-1190818.html Floating Point Bug]

1.4.0_01 java plugin proxy config with password / plugin options???

I have the 1.4.0_01 java plugin installed and I'm running with Mozilla 1.1. I'm behind a firewall -- the plugin is configured to use browser settings.
So it accurately fetches the proxy server & port config. but then every time I hit
a page with multiple Java classes, a popup window appears asking for my username/pw.
I enter it 10 times to dl each class and then the java app runs.
Is there a way to expedite the username/password entry by storing it in a command
line option for java? Perhaps there is an environment variable I can set?
I saw similar options -D javaplugin.trace.filename but I have no idea what
the option would be for this...
Thanks!

This can only be done by the applet, I posted a bug to sun concerning this issue, as it is a regression with plugin 1.4 but they set it to wontfix.
http://developer.java.sun.com/developer/bugParade/bugs/4677535.html
In 1.3.1 the PluginAuthenticator was used to store all password information and reuse the information as long as the vm kept running. But as of 1.4 this behavior is changed, and the password information are only kept for the single applet and the possibility for the applet to retrieve this information is gone (and be able to store it elsewhere).

Forms Web application is not working on FireFox Browser-with java plugin

Hi All,
We are running custom build forms application using forms 10g and application server 10 g Rel 2. We are using Java Plug-in 1.5.0_06. The application is working fine before recent update from firefox .Now it's not working and keep on asking additional plug in required and taking to java.sun.com for installing the plug in. Even after installing when we access the application it will do the same thing. I tried uninstalling the firefox with the older version and with diffrent java plugin versions.. but the problem still there.. any help will be mush appriciated...
Thanks...

Fedora 13: After upgrading from FF3.6 to FF6.0.2 I no longer have a Java plugin. How do I configure the Java Plugin for FF 6 ? There is no Java Plugin at the site

I am Fedora 13x64 bit. I just installed FF v6.0.2 from the FF download site. I backed up the existing FF 3.6 as firefox_old
I need to have a Java plugin to access company site, how do I configure the Java Plugin ?
At the Plugin area in FF6 there is no Java Plugin available, even after a search.
I have Java 1.6.0 installed in the OS at:
/usr/lib/jvm/java-1.6.0/jre/lib/amd64/libnpjp2.so
I googled how to configure Java Plugin for FF 6 for Fedora 13 and the trick was to create a soft link from /home/<userID>/.mozilla/plugins to the above libnpjp2.so

You can try the applets at this Sun location and see if any of them are "slow".

Java Plugin 1.3.1 on RedHat Linux 7.1

I downloaded and installed the Java SDK 1.3.1 for linux.
When I try to view an applet written in Netscape I get the following error message on the bottom left corner of the browser window:
ClassdefError javax.japplet not found.
However, I can see the applet in the appletviewer.
In order to install the plugin I did the following:
I removed the old plugin:
rm -fr $Home/.netscape/.java
rm $Home/.netscape/plugin/javaplugin.so
Then, to install the plugin I set the netscape environment variable :
export NPX_PLUGIN_Path = /usr/java/jdk1.3.1/jre/bin/plugin/ns4/javaplugin.so
How can I tell whether the netscape 4.7 browser is using this plugin??
Could someone please tell me what is causing the error?? Please be very specific, I am new to RH Linux.
Thank You

try to make a link to your java plugin from netscape plugin directory:
cd your_netscape_dir/plugins
ln -s /usr/java/jdk1.3.1/jre/bin/plugin/ns4/javaplugin.so try to fid netscape dir in /usr/lib/netscape/ or /usr/local/netscape ..

I am running 10.5.8, and just updated my java to java 5 update10. Now my firefox is missing the Java plugin, and I can't load any Java applet at all. When I try it with Safari, it hangs when certain Java applet loads. HELP!!!

Suddenly my Java plugin is missing and i can't load any Java with Firefox at all, even though i have it enabled in the browser! i've tried loading in java embedding plugin, but it doesn't work. what should i do???

It's not in Tools> Add-ons >plugins? Should be Java Plug-in 2 for NPAPI browsers 13.5.0. What are you seeing there? I don't think it's called the embedding plugin any longer.
Might try getting the Firefox 5 standalone application. Trash the current one and replace it. Doing this won't affect your Profile or any settings.

If it's enabled, how can it be missing?
If this doesn't work, ask here. No need to register. Make sure you put (Mac) in the title.

Java plugin causing Firefox to crash

I installed the newest Java plugin today and it asked me to restart Firefox. Now it crashes as soon as I open it. It will not open in Safe Mode because it won't stay open for more than half a second. I tried re-installing it and restarting my computer and it's having the same problem. I can't open about:crashes because it won't stay open.

Make sure that you've installed the 32 bit Java version because Firefox is a 32 bit application.
