Java Plugin + Http Auth

Hi.
We are currently using the jre 1.3.0 for viewing a ticker-applet which resides in a htaccess/htpasswd protected directory on the webserver. Currently most client-workstations have been upgraded to jre 1.3.1_09 (req. for other applets) and now everytime someone tries to access the ticker-applet the usual ie login/password dialog pops up (which is ok), the jar gets loaded, then the java plugin FORCES the user to login again (if the user/pass were entered again the ticker loads and works) ?!?
We haven't changed anything except the jre version from 1.3.0 to 1.3.1_09.
Could anyone please explain this behavior or has a fix/workaround ?
Thanks,
john

This behaviour is browser and plugin specific.
If you want a solution that is independant of these, (however requires apache, access to httpd.conf (although may work from .htaccess), and requires your applet tags to be cgi generated)
See the thread
Browser pre-authentication

Change log pattern on Java Plugin traced logs

Hello,
I have read the following documentation about Tracing and Logging information from the Java Plugin.
http://docs.oracle.com/javase/6/docs/technotes/guides/deployment/deployment-guide/tracing_logging.html
Configuring the following properties through Java Console Panel:
-Djavaplugin.trace=true
-Djavaplugin.trace.option=basic|net|cache|security|ext|liveconnect|temp
-Djava.security.debug=access:failure
However, I cannot find any information concerning how to specify the log pattern of the information traced. Basically, I need to append the timestamp of each generated trace message.
Please, is there any config parameter to set on JRE Control Panel in order to change that log pattern?
Thanks in advance!

Sounds like the server can't find the JAR file on its classpath. Have you tried putting the jar into one of the directories already on the path? Check out the opmn.xml to see what is already configured.

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

Any steps that you can take to isolate the problem to specific Java versions, browsers, applets, web sites, operating systems (and versions), etc, would enhance the possibility of getting help.
You can try the applets at this Sun location and see if any of them are "slow".

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.

EDIT. Oops, may be different for 10.5.8. Was thinking recent Java update for 10.6. But try installing a new app anyway. In the past, this got me the latest Java plugin.

Java plugin not working on any browser (64-bit system)

Hi there!
I'm having a major problem with running Java plugin on all of my browsers (Opera, Chromium and Firefox) under my Arch Linux 64-bit system. The system is fully up-to-date, and Java plugin is being displayed among other plugins on "about:plugins" screen. The Java Environment was installed from Community
[zbyszek@barca ~]$ yaourt -Qs jre
community/jre 6u24-1
Sun/Oracle's Java Runtime Environment
Any ideas how to solve this?

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.

The Java plugin has created a time unfriendly issue with my e-mail account, I can not open or send any e-mail without using this plugin, how can I eliminate this problem without dropping m. firefox?

A few days ago I tried to e-mail a friend, when I started A box came up and it required me to add a plugin..Java. I contacted my e-mail courier and microsoft, they told me that is was a plugin from Mozilla Firefox. Since then I must go through Java to send or open an e-mail... this is NOT to my satisfaction, it takes too long for all of this to open and if it is not cleared , I am dropping Mozilla and going elsewhere. Why has this occurred? Is this a result of the last update? If so can I delete the last update and continue on the other version?
== This happened ==
Every time Firefox opened
== last week

Sorry, I have no idea what you mean by '''"The Java plugin has created a time unfriendly issue with my e-mail account, I can not open or send any e-mail without using this plugin,"'''.
If you think your problem is caused by the Java plugin, you should visit the Java support forum for assistance.
http://forum.java.sun.com/index.jspa
If you could explain what you mean by '''"time unfriendly''' issue with my e-mail account", maybe we'll be able to help you solve that issue.
It might be helpful for us if we knew exactly which web-mail provider you are using. It seems strange to me that viewing or sending web-mail would actually "need" Java for operation, its more likely that some other item on the web page needs Java to run some advertising or other garbage that isn't a necessary part of the web-mail functionality you want to use.

How can we install the Java Plugin from the html page

Hi,
I am using java plugin 1.3.1_02 for my applet pages.
How can I install that plugin in the client machine without installing manually.
I used,
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width="600" height="400" align="middle"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,1,2">
<PARAM NAME="code" VALUE="SignedAppletDemo.class">
<PARAM NAME="archive" VALUE="SSignedApplet.jar">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
</OBJECT>
But it is downloading java plugin 1.3.1_03.
Can anybody help me
Thanks & Regards
Raja

Using object tags is the correct way and only way to download the plugin and let the client decide whether he can download it r not. There is no way to install automatically
I dont think there is a way to install automatically without a user intervention coz, it can open the floodgates for potential hackers.
Can u cite an example about which programs can be installed automatically and why do u want the plugin to be installed automatically?

I have windows 7 64bit. When i installed firefox and then java, i do not have java tm platform or any java plugin. I can't watch free movie's online!!

As i told i have Windows 7 Ultimate 64bit version. I install java and have problems with Java Deployment Toolkit and Java(TM) Platform SE. It won't show in add-on. I cant watch movies. When I play movie it says java is missing but when I use IE I can watch some movies. I try reinstaling Java and even reinstall Windows. But problem was still there. I run java check (from Firefox) to see if java is installed and it confrmed. I even try diferent versions of Java and Mozilla. I even use JDK and JRE. I install java for 64bit and mozilla is also for 64bit version of system.
I have another laptop with 32 bit version and everything works great. Installation procedure was same (only used 32bit versions of softwares).
When I go to control panel and java options (windows 64bit) enable java content in your browser is marked. But in advanced tab default java for browser (mozilla family) is unmarked. And when I mark box and leave (apply then ok) and return box is empty. It wont confirm. In 32bit version of laptop i have alsou java plugin but in 64 bit it is not there. Here is a picture what I was talking about. This is on windows 32 bit for 64bit is some just box for mozilla family is empty and under that java plugin do not exist.
[code]http://s23.postimg.org/dl4dun4p7/Untitled.jpg[/code]
hope someone have solution!!

you don't have to reinstall firefox or java, you can just download and install the 32bit-java next to your currently installed java version. it should then be picked up by firefox and be displayed under firefox > addons > plugins...

Does Firefox support java applets if the "Next generation plugin" is disabled via the Java plugin control panel.

I'm still trying to get a definitive answer to this question.
My applet is not "Next Generation compliant". When we run our applet in Internet Explorer it runs fine as long as we disable the "Next Generation Plugin" via the Java plugin control panel. However our applet does not run in Firefox if the "next generation applet" is disabled.
Is it a requirement that if I want to run an applet in Firefox 3.6.x or higher that the "next generation plugin" be enabled via the Java plugin control panel.

Current Firefox versions (3.6 and later) can only run Java applets via the Next Generation plugin.

How do I get the SUN Java plugin to work in Firefox 8.0 or Seamonkey 2.6?

After a recent automatic upgrade of Firefox on my Xubuntu 11.04 system, the SUN Java plugin is no longer recognized by Firefox. I tried the old method of manually symlinking the corresponding library to /usr/lib/mozilla/plugins and various other directories that contained plugins, but to no avail. Other plugins like Flash work fine.
Having the SUN Java plugin working is a must for me in order to be able to access my online bank, the Citrix server at my workplace, etc.

Also,
Exit Firefox and rename the '''pluginreg.dat''' in your profile folder and start Firefox again. This may help to reinitialize the plugins that Firefox recognizes.

How do I fix my Java plugin?

In my Firefox browser, I have two potentially vulnerable plugins: "Java Deployment Toolkit 7.0.400.43" and "Java Platform SE 7 U40." I uninstalled Java Platform (I believe it was 6.0), so I'm not sure why it is showing as a plugin. Anyway, in my attempt to uninstall the Java 7 Update, I get an error message that says "The feature you are trying to use is on a network resource that is unavailable." I'm prompted to "Click Ok to try again, or enter an alternate path to a folder containing the installation package "jre.1.7.0_21-c.msi" in the box below.
It appears that a folder within my c drive is missing. I don't understand it as this is a file that I do not mess with. Apparently, it is the subfolders within the c drive; specifically, the appsdata subfolder was hidden! Even after I unhid it, I'm still missing the local subfolder which is where Java normally would go. Java is instead located on a local low subfolder, but I can't uninstall this because this path (Local low) is not recognized). Any help is much appreciated!!
I am not a computer geek, so can you please provide the answer in as simple a manner as possible? Thank you in advance for your time and efforts.

The first thing you should do is to '''uninstall''' older versions of Java. <br />

Java Plugin won't work in Netscape 7.1

I'm using Windows XP Home with Netscape 7.1, and the Java plugin won't work.
Java Plug-in 1.4.2_05 for Netscape Navigator (DLL Helper) is listed 7 times in Help>About:Plugins;
The Java Plugin works in Internet Explorer (I use the Test Java Virtual Machine to determine this). With Netscape, I just get the "Click here to get the plugin" window, and believe me, I've clicked here many times, and gone through the installation process, and it still doesn't work. I've uninstalled Java, rebooted, and installed it with the browsers closed, and it still doesn't work. Everything else in Netscape seems to be working properly.
Under Edit>Preferences>Advanced in Netscape I have "Enable Java" checked.
I posted this problem in the Windows-BBS Netscape and Mozilla forum, http://www.windowsbbs.com/showthread.php?t=33994, and tried everything suggested there, but it still didn't work.
Anybody have any suggestions?

I was facing a similar problem. I think the problem is with different versions of JRE. For example, I was trying to associate with Netscape the JRE version of 1.4.2_01 without any success. But on associating jdk version 1.4.2_05, it started working fine.

Trying to download the Java Plugin is an impossible situation ! Help ! !

Dear People,
You cannot believe what I have been through trying to do a first applet !
A long time ago downloaded a version of the plugin (a cup of coffee icon in the control panel). Then recently I downloaded a new version
(1.4.1_01) (a second cup of coffee icon in the control panel)
Well I was not able to run my first applet after creating a good
batch file (with help of course) named javacompile:
echo off
cls
PATH=C:\j2sdk1.4.0_01;C:\j2sdk1.4.0_0\bin;C:\j2sdk1.4.0_01\lib;C:\WINDOWS\jbproject\objectdraw.jar
javac -classpath C:\WINDOWS\jbproject\objectdraw.jar;C:\WINDOWS\jbproject %1
my program MakeBox.java compiles ok at the Dos prompt
when I open the MakeBox.html in the browser the error message says:
"The required component is not available for this version of windows"
I was told to uninstall the plugin and download it again
So I took 50 minutes to download it and the message said:
"You already have the jre1.4.0_01 do you want to uninstall ?"
so I said "no" ... was this an idiot move on my part?
then it continued to download the plugin and when it was done it said:
"You already have the java plugin, do you want to uninstall it?"
I answered "no"....was this also an idiot move on my part??
What to do ?
totally confused

Dear People,
I just received an e-mail letter from the author of
"A Eventful Approach" Thomas Murtagh ! ! !
The most advanced Java paradigm text for Java beginners ! !
http://applecore.cs.williams.edu/~cs134/eof/
Even though his letter is very clear, my brain doesn't know what
to do in the context of compiling at the Dos prompt, (trying to do my
first applet). Below is the letter and then the code to MakeBox.java
and MakeBox.html Please shed some light for me.
Thank you in advance
Stan
I meant that in our definition of the WindowController class, we said:
public class WindowController extends Applet {
So, when you say
public class MakeBox extends WindowController {
the MakeBox class you define is (indirectly) an Applet. In particular,
with most Java programming environment, you can run the program as an
applet (i.e. using Sun's appletviewer or JBuilders applettestbed).
Tom
Here is the code:
import objectdraw.*;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class MakeBox extends WindowController
public void init()
this.setSize(new Dimension(400,300));
public void onMousePress(Location point)
new FilledRect(40,80,30,20,canvas);
