Checking if the Java Plugin is present in IE

Hi,
I've been trying to find out how I can check if the Java Plugin is present in IE. In Navigator it's easy but I do not know how to do it for IE as it does not work the same
way, through using the navigator.plugins Array. However, I know that in IE you can try to create an ActiveXObject but you need to know the plugin name and I do not know this.
Can anyone help?
Cheers,
Mark

This seems to be more of a JavaScript question than a Java question.....
If you used the HTMLconverter, the <EMBED> tag should contain the necessary information for IE to determine if the viewer of your document needs to download a newer version of the plugin. Should the veiwer decided not to download the appripriate plugin or doesn't have the correct plugin, your applet would not work and if you try to access document.APPLETNAME (where APPLETNAME is the name given to the applet), you will either get a null or undefined -- that should provide you with sufficient information on what to do next.

How do I disable the java plugin?

I have already done
-tools->Internet options->Advanced
- unchecked 'use java2 1.4.2_04 for < applet> (requires restart)'
- checked Microsoft VM java console enabled (requires restart)
- reinstalled the MS JVM (MSJavWU_8073687b82d41db93f4c2a04af2b34d)
- set my class ID to
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"> which is supposed to be for MS
Every time I run the applet, the java plugin console appears with 1.4.2_04 version running.
what else can I do?

I created my applet using 1.4 and I want to be sure that it works for people without the plugin. Applet tags alone cause a gray box, while Object tags work but seem to invoke the plugin.
Also is there a way to check the highest JVM/ plugin version needed for my applet? I don't want to have to manually thumb through javadocs for each object in each file to check when it first appeared. I also don't want to have to download each environment and try to compile the applet.
Thanks.

Hi, I have the newest update of Fire Fox which is 10.0.2. I can't get the Java plugin to download to Firefox.

I am wanting to get Java working on Firefox so I can utilize chat rooms and other programs that use Java, and no it is not Javascript that I am talking about. Every time I go to a site that utilizes Java it tells me that I need to download the Java plugin. When I click on the link it starts to download the Java plugin, but instead of installing the plugin it installs Java for Internet Explorer instead.

Hi johndoe3815. You can check out how to download and install Java for Firefox in this page:

Can't get the Java Plugin to load

I have tried installing the Java Plugin several times but it does not work. I get the message that Java installed correctly but when I try to start the web page I am working in that uses Java I get the message that I need to install the Java Plugin. I have restarted Safari, cleared the cache and even restarted my machine. I cannot get Safari to recognize that I have installed Java. Any ideas? Presently I am working in Safari for Windows. Works fine in Safari for my Mac. Wish I could take my Mac to work!

Hi,
I see you've posted on this topic several times. You didn't mention here:
http://discussions.apple.com/message.jspa?messageID=9078749#9078749 that it's Safari for Windows that is causing the issue.
When you cross post, it makes it that much more difficult for us to help you as it takes longer to put all the information together.
I'm going to ask a moderator to move this post over to the Safari for Windows forum.

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".

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.

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.

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);

How to access the Java plugin certifcate store from a signed applet?

Is there any easy way I can access the certificates in the Java plugin certificate store?
I think I can load the C:\Documents and Settings\<login user>\ Application Data\Sun\Java\Deployment\security\trusted.certs into a KeyStore and examine the certificates that way.
But I just wonder if there is more robust way to do this without loading up an external file since an applet is executed within a Java plugin.
Thank you :)

Is it possible to open the Java plugin / WebStart Console from my app ?

Hi,
I would like to know if it is possible to add a menuitem to my application that would start the Java plugin/web start console.
That would be nice when people have errors in my application.

Thanks for the information, but is there a way to do it without using exec methods ?
I just want to bring up the Java Console from my app, in the more portable way possible ;-)

Installing the Java-Plugin without administrative rights

I would like to find a way to allow a user without administrative rights to install the Java-Plugin for using Java-Applets. As far as I understood, the plugin can be installed in a silent way withou registry modifiactions. Is this working for users without admin rights?
Furthermore I would like to have the web page containing the applet installing the plugin (if necessary) in a fully automatic way so the user does not need to deal with installing the plugin manually. This should work without admin rights as well.
Any ideas?

without admin rights?Could anyone please explain, why it is so difficult for Sun to create an installation package for user without admin rights? The whole "GetJava"-program is just crap for ordinary users if they get the JRE downloaded seamlessly and then the installation fails due to missing admin rights. This way Java would never succeed on the desktop.

JavaScript to Java with the Java Plugin, anyone?

The java.sun.com web site seems to be teeming with docs on how to access JavaScript from Java, and the Netscape site seems to have plenty of docs on how to access Java methods from JavaScript using the browser's own JRE.
But can one use JavaScript to access methods of a Java applet running under the Java Plugin? And if so, how?

all the public methods and fields of an applet are exposed to javascript. In the <applet> tag, set...
<applet ...otherinfo... mayscript></applet>, or
<applet ...otherinfo... mayscript="true"></applet>
I think the latter version is safer to use, as I think IE has issues if you just use the mayscript tag without the "true" value.
So if that is set, in javascript all you have to do is address the applet, and call any of its public fields/methods. (Actually, I know you can call all public methods and I think you can call all the public fields as well...)
var applet = self.document.applets[0];So now you can call all the public members, such as...
applet.start();
applet.stop();
applet.myPublicFn1();
applet.myPublicFn2(arg1, arg2);
var val = applet.pubField1;etc.
Note that if you're using Java2 (swing) thru the object/embed tags rather than just using the applet tag, things don't work that smoothly. I tried once and the applet wasn't actually found in the applets collection of the document. I tried finding the 'applet' object but had no such luck...
Hope that helps.
Good luck.

How can i change font used by the java plugin?

im running j2se 1.4.0 on win2k, and the java plugin is using a font that is not readable because sized way too small (also, the font is not a 'standard' font).
the font is also applied do class loading or exception messages in java applets (in IE5.5, but i don't think that this is browser-related).
is there a possibility to change to font (or the font size)?

thanks for the tip, but this problem seems not to be tightened to the font.properties file:
the wrong font is only used with the j2sdk1.4.0 plugin, not with that from j2re1.4.0 (actually, i had installed jre first, and afterwards j2sdk without removing j2re before). changing the plugin used back to j2re made the java console display the correct font (though the font.properties files were identically in both cases).

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.
http://www.mozilla.com/en-US/firefox/all.html
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.
