Java browser plugin

Hi,
after upgrading to Lion, I recognize that Applet are no longer run as part of the browser process, but in their own. This ***** big time, as several application my company uses rely on the browser's function as helper application. Any thought on how to get applet into the browser again?
thanks!

Same here. Is there any way to put applet back to browser process in Lion?

Java browser plugin failure

Heya!
I bashed and crashed away trying to get the javaplugin working for Moz last night but to no avail. This is the error when launched from the terminal:
LoadPlugin: failed to initialize shared library /opt/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.so [libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory]
Easy enough I thought lets just try making a symlink like so:
ln -s /usr/lib/libstdc++.so.5.0.0 /usr/lib/libstdc++-libc6.1-1.so.2
Still didn't work it produced this output:
LoadPlugin: failed to initialize shared library /opt/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.so [/opt/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.so: undefined symbol: __rtti_si]

I am using the GCC3 tree if that is any help.
Java is not a huge concern but it would be a bonus to have it. I only need it for my browser.
Thanks in advance.

JAVA Browser Plugin for Mozilla on Linux Debian

Hi!
I run a Mozilla Firefox (iceWeasel) on a DEBIAN.
It does NOT display german or french special characters like "Umlaute öäüÄÖÜß" and alike properly.
The text is displayed within an Applet from a 3rd Party, so i can only change the text which is displayed but no java sourcecode.
The stuff is displayed properly on Windows with IE and Firefox.
Any idea is appreciated!
Best regards,
Roland

Next-Generation Java 7 Plugin Performance on Windows 7 and IE 8

Applet performance has historically been a black eye, to say the least, for Java Applets. Slow load times over today's networks are simply not tolerated by today's network standards. I'm currently supporting an Applet that is forced to move to the Java 7 Platform. As such, we are particularly sensitive to anything new that may further hinder applet performance. To that end, I've been doing quite a bit of benchmarking lately of Applet load times using various configurations with the Java 7 Plugin on Windows 7 using IE 8.
To capture Java Applet load times, I've simply been marking the start time in Javascript from the HTML onLoad() event, and then calling out to a similar Javascript function to mark the end time from the bottom of the init() method in the Java Applet. I subtract the two times to get a general idea of how long it takes to load the applet.
The best load times, so far, (when loading the JARs from the web server) occur when caching is employed (e.g., cache_option, cache_archive, cache_version). What I've noticed though, is that when everything else is the same, the performance is degraded by at least half when I check the 'Enable the next-generation Java Plug-in' in the Plugin Control Panel. Applet load times slow down by at least half when this option is enabled. When loading JAR files from the web server, with caching in effect, the applet load time performance is comparable to loading JAR files from the file system only when the next-generation plugin is not enabled. I assume this is because of the associated overhead of spinning-up this external JVM process, but I'm not certain.
Does anyone know if this is a correct assumption? And if I'm correct, are there ways to speed up the loading of an applet when caching is used with the next-generation plugin? Is this another cold-start vs. warm-start issue for the JVM?
My goal is to have applet load times for JARs loaded from the web server, using the next-generation plugin, as fast as when the JARs could be loaded from the local file system (which apparently is no longer possible using the next-generation plugin, sadly).
Thanks!

Thanks Igor.

<PARAM name="type" value="application/x-java-applet"/>
</object>
Here's a brief synopsis of my test methodology:
Assuming caching is the fastest performance I'm going to get by putting JARs on web server, goal was to determine if browser plugin and next-gen plugin will offer the same performance in terms of time to load the Applet.
To test, I unchecked the 'Enable Next-Gen' plugin option in the Java Plugin. I updated the cache_version values for all JARs. I 'touched' all JAR files in the WAR (I use cygwin) and redeployed the WAR. I have a cli script that launches IE and points it at my applet. When the applet loads, a Javascript Alert box displays showing the number of milliseconds it took to load the applet. I document the time, quit the browser, and re-execute my script. I do this 10 times for each test scenario and take the average.
The two basic test scenarios are using the Browser Plugin (not next-gen) and using the Next-Gen Plugin. That is the only variable I change between test scenarios. Here is the raw data I collected for each test scenario:
Not Using Next-Gen Plugin (milliseconds):
run1 run2 run3 run4 run5 run6 run7 run8 run9 run10
1761 474 535 495 500 505 502 267 693 513
Avg: 625ms
Using Next-Generation Plugin (milliseconds):
run1 run2 run3 run4 run5 run6 run7 run8 run9 run10
5382 1529 983 1545 1622 1575 1544 1544 1545 1529
Avg: 1880ms
The time it takes to load for each first run indicates caching is happening as subsequent runs are faster. I verified that the JVM is not making http requests for cached JAR files by proxying these requests with Tcpmon just to confirm this was the case.
I'm basically just looking for a logical explanation to account for the significant time difference that occurs from this Plugin configuration change. It seems to make logical sense to me that this can be explained by JVM Process start up time, but I'm looking for corroboration on that or another explanation.
Thanks for any advice, help, etc. I'll start looking into JNLP and JAR index as well.

JRE 1.4.2_04 doesn't install Java browser Plug in... :(

As the title say, therefore I had to uninstall 1.4.2_04 then reinstall 1.4.2_01... the "Browser Plugin Installation" Screen with two check boxes (Internet Explorer and Netscape Navigator) from 1.4.2_01 disappeared in 1.4.2_04, what's up with this?

It appears that the version string has been dropped from the Control Panel plugin. Look for a Control Panel entry simply titled "Java".
I've also noticed that it is no longer possible to manage different JVMs on my client machine starting with 1.4. The 1.5 installation takes over the Control Panel console, thereby essentially eliminating my ability to select 1.4.2, etc.

[Solved] No audio through Java browser apps...

Hello.
I'm running 64bit Arch, the Alsa sound system, and the offical Sun Java RE. When I go to use java apps with audio, I'm not receiving any type of ouput. All other forms of audio on my system seem to be working, so I'm unsure where to begin troubleshooting.
Where do I start?
EDIT;
Use 'aoss' instead of 'alsa-oss'. I made the mistake of thinking it was the name of package that needing to be entered.
Last edited by Who'sThere? (2011-08-31 14:35:05)

Try running those pulse insctructions but using aoss instead of padsp (that requires only the alsa-oss package, not pulseaudio). It should work, but OpenJDK already should work fine with ALSA by default...One thing I've noticed before is sometimes if I use the openjdk browser plugin, sound doesn't work, but in non-browser applets it works fine...but I haven't tested that in quite a while. The aoss thing should fix Sun JRE too (that's what I originally used it for, because Sun JRE's sound is...a little funky).

Cannot get Java Web plugin to work in Safari.

I have been using the JAva web plugin for a while, and managed to get past the problem with the Oracle Java 7 plugin successfully, but today, the Java web plugin is not working for me at all, and I'm struggling to find out why.
When I visit java.com and run their detection page, afer about a minute, it comes back with "We are unable to verify if Java is currently installed and enabled in your browser."
I've followed the advice at http://support.apple.com/kb/HT5559 on how to re-enable the old Java 6 web plugin, I've tried reinstalling the Oracle plugin... but no matter what I do (restarting Safari, enabling disabling Java in Safari preferences, rebooting the Mac), I still cannot get it working in Safari.
This is a massive problem as website myself and my 20,000 colleagues use to log in to work remotely depends on the Java web plugin. Right now (as in this morning)... the only option I have is to use a different OS (i.e. Windows).
Longer term, I really want to get this working on OS X again - any advice on further troubleshooting?

Apple has barred Java from running on Macs, leaving companies that rely on Java plug-ins out in the cold.
Apple blocked Java 7 Update 11 by adding it to the banned list in XProtect.
This is the second time in two weeks that Apple has blocked Oracle's code from running on Macs. This time Java is blocked through Apple's XProtect anti-malware feature.
Java has come under fire as the means by which hackers have been able to gain control of computers. In April 2012 more than 600,000 Macs were reported to have been infected with a Flashback Trojan horse that was being installed on people's computers with the help of Java exploits. Then in August Macs were again at risk due to a flaw in Java, this time around, there was good news for Mac users: Thanks to changes Apple has made, most of us were safe from the threat.
Unwilling to leave its customers open to potential threats Apple has apparently decided it's safer to block Java entirely.
Macs running OS X Snow Leopard and beyond are affected.

DOMNotSupportedException in com.sun.java.browser.dom.* classes

I'd like to enable an applet to modify the DOM in a browser window directly (ie. by using org.w3c.dom.* stuff). I'm using the latest 1.5.
I'm using a small class that I've pasted below to attempt to facilitate this. It evidently works in MSIE, where I receive the "Got document" message indicating a non-null value for 'page', but in Mozilla or Netscape, I get the following exception thrown:
netscape.javascript.JSException

Got document: null
Is this just simply only supported for MSIE? This seems highly unlikely.
I suspect it might have something to do with permissions in Mozilla, as these lines also appear in the log:
liveconnect: the url of the applet is http://word and the permission is = false
liveconnect: JavaScript: calling Java system code
liveconnect: JavaScript: default security policy = http://word
I haven't yet found anyone who could explain them. I'd like to try playing with permissions, buy I don't know how to do so. Any suggestions?
--- code follows ---
import javax.swing.*;
import java.applet.*;
import org.w3c.dom.*;
import com.sun.java.browser.dom.*;
public class ClientLink extends JApplet implements DOMAction {
DOMService service;
Document page;
public void start() {
try {
service = DOMService.getService(this);
System.out.println("Got service.");
service.invokeLater(this);
catch (Exception e) {
e.printStackTrace();
public Object run(DOMAccessor doma) {
System.out.println("Entry successful.");
try {
page = doma.getDocument(this);
System.out.println("Got document: "+page);
catch (Exception e) {
e.printStackTrace();
System.out.println("Error: "+e.toString());
return null;
}

A couple of things I've found with DOMService and/or LiveConnect and the more recent java and browser releases :
1) You probably need to edit your java.policy file to grant permissions since the security in Java is now managed independently from the browser
2) You need to remember to have mayscript="true" in your applet tag
3) JSObject's dont work unless you've called JSObject.getWindow(...) first.
4) Many legitimate java exceptions will appear misleadingly as security exceptions

Using standalone browser plugins in extension

I want to know if is it possible to use standalone Web Browser Plugins(like Google Earth, Adobe Reader or some I created) in Extension ?
Asking this weird question because, I must use Win .dll s and searched about applet and knew that it won't help me.(source http://docs.oracle.com/javase/tutorial/deployment/applet/security.html)
Another solution to do this is possible on browsers by creating own plugin. Google kicks-off NPAPI based plugins from chrome after this September and they created PPAPI structure. This may be a solution for me
to use win dlls but I don't know its useful in extension structure ?
Or if someone have any idea to this issue ?

If you use a symlink to link to the libnpjp2.so files then you might be able to include the Java version in the file name and have two links (libnpjp2-7u25.so and libnpjp2-7u55.so).
Note that you can also create a plugins folder in the current Firefox profile folder or in the ~/.mozilla folder (~/.mozilla/plugins)

IE6 Java one plugin

I have just reinstalled windows XP on my computer to find that the install on demand java plugin is no longer available from Microsoft.
I have tried the Java 2 plugin, but it causes my Desktop X dockbar to flash in an annoying manner whenever my browser is open. Does anyone know where I can get a an older plugin for my browser?
I only need it to display applets.

How do I stop downloaded MP3s playing in the QuickTime Browser Plugin?

I have a number of websites created in Flash, which are used to promote musicians and bands in Bristol, UK. I use Flash because it allows animations, music players, background music, and all the other features ideal for promotional websites.
We offer MP3s for free download so our fans and followers can own some of our tracks.
Up until last week, a link directly to an MP3 would launch the "Save As..." download dialogue, allowing users to save the files to their PC.
However, since installing QuickTime 7, when you click on a link to an MP3 it now launches a nasty little embedded Quicktime player, which you can't save from or do anything useful with.
This is absolutely useless as I already have streaming audio and a built-in music player in my site, and I can now no longer offer MP3 downloads. I don't want to have to start zipping my MP3s or anything hideous like that, does anyone know a way that I can stop this happening?
I can't expect visitors to my sites to do anything, so I need some way of changing the URL so that it doesn't trigger the QT plugin.
Would really appreciate some assistance as this has effectively ruined the most significant part of most of our websites.
Thanks

Ah, well, it was worth a try, but since you're clearly not actually reading my post - I'm using FLASH, as I clearly stated so you cannot right click.
As for the QT Mime settings, what you are saying is woefully inaccurate, and once again you aren't reading what I am writing. Quicktime is not the default player for MP3s on my PC. And as of two days ago there was no QT MP3 browser plugin either. I installed Quicktime because I have to have it to play MOV files.
By installing QT the program arbitrarily (that means it did it without any involvement or permission from me) took ownership of MP3s in the browser only. I know how MIME settings work, and I made absolutely sure that QT did not get it's hands on any of my filetypes. However, there is NOT an option to stop it playing MP3s in a browser, and it most definitely happened without my say so.
There clearly isn't an answer to this, I'll either have to put my MP3s in Zips or use some elaborate code to generate a nasty HTML page so that you can (retch) Right Click, Save As. All this because the QuickTime player has made changes that it had absolutely no right to.
Never mind, I'll find another way. But first, I'm uninstalling Quicktime forever.

Adobe Reader Browser Plugin - How to disable right click print

Here is some background to my question
I'm using Adobe Reader 9.2 and have configured to use the Adobe Reader Active X browser plugin.
which has the effect of launching pdf's within the IE browser rather than launching the full client. This is all working fine
I have a requirement that I need to lockdown certain menu items (for the purpose of this example, lets say "SaveAs" and "Print") and toolbars which I have also done successfully using folder level javascripts. For example I have created a HideMenuItems.js file and placed this in the "C:\Program Files\Adobe\Reader 9.0\Reader\Javascripts", here is a snippet of the file which relate to hiding / removing the SaveAs and Print items
app.hideToolbarButton("Print");
app.hideToolbarButton("SaveFileAs");
app.hideToolbarButton("Save");
These work fine and hide the Print and Save toolbar buttons from the Adobe Reader Browser plugin menu.
As an aside If I wanted to hide the same icons from the full adobe reader client I could use app.hideMenuItem("Print");
So this all works fine and I'm happy so far. Now, with these settings in place I launch the pdf within the browser, although save and print buttons are now hidden and I cannot add them back, I can still RightClick anywhere in the pdf and get the context menu, from there I can select print.
What I'm after is a way to either
(i) Selectively remove menu items from the right click context menu, and therefore remove the print option e.g something like app.[hideRightClickMenuItem]("Print") would be great but I dont know what that method is called.
or
(ii) Disable the RightClick context menu altogether for Adobe Reader Browser Plugin
Not bothered what the solution is whether its a reg hack - HKCU / HKLM / or javascript line I can add to my HideMenuItems.js, But basically I want to lock down the ability for the users to select print button from all sources including "CTRL + P",
Or if this is not possible let them hit CTRL P or right click print, but then not display the Adobe Print Dialog.
Basically the printing of the documents in handled by our web app sending a silent print to the adobe application which again works fine, I just need to prevent the users from being able to initiate a print from within the pdf when displaying the pdf in a browser.
Having searched around there is an API called AVAppRegisterForPageViewRightClicks which is supposed to prevent right clicks, But I dont know how to use this, or whether it can be used within my HideMenuItems.js file, tried many different syntaxes but to no avail.
Does anyone have any experience in this? Adobe - do you have any suggestions ?
Cheers
Will

Hi thanks for your response, yes it seems this API is availalbe but there are no examples of how to use it. You mentioned its available in Adobe reader and Adobe Acrobat plugins. Well I'm using the Adobe Reader Active X Browser Plugin so how would I use this API to restrict the Browser plugin.l
I am not a developer writing my own custom plugins, I simply want to use the out of the box adobe reader product, specifically the Active X browser plugin, but I need to be able to customise and restrict what the user is able to do.
The reason I need to do this is that we publish IE on a citrix server which users access to launch this highly secure web based application. The sensitive data that they view is in the forms of PDFs which are viewed by the Adobe reader browser plugin within the browser. The web application controls who can save, export, print etc, so I need to be able to lock down the Adobe Reader Active X browser plugin so that the user cannot initiate save, and print functionality from within the viewed pdf. I've done this successfully by restricting the menu and toolbar items but it is still possible to right click on the viewed pdf and click select print from the context menu. This would cause us a big security flaw, which would result in users that are only supposed to view being able to click print.
I published a desktop (locked down) and published IE (locked down) all successfully with GPOs so the users cannot do anything they are not supposed to do, however Adobe reader it seems cannot be easily locked down and this is a problem as I might have to start looking at viable alterantives. Surely a simple requirement as this could be acheieved with relative ease.
In an ideal world there would be an available GPO template (.ADM file), which could be used to centrally manage these type of settings. I dont even mind writing an ADM myself, I've written many before, but for example what I need is the appropriate registry entries and how they are used to lock down / restrict certain functions so that I can write such an .ADM file.
I dont mind how I achieve this, I just need a way to do it. So if using the API AVAppRegisterForPageViewRightClicks would achieve this, can someone please tell me how I can implement something that would use this API to restrict the right Click Print options for example.
The sort of answer I;m looking for would be
Create a file, paste in this code, place the file is this location xxxxx, this is a per machine fix so will affect all users
or
Edit the regstry and make this HKCU change xxxxx - This is obviously a per user fix so use normal methods to get this into every users profile.
or
Open up the file in this location xxxxxx and add AVAppRegisterForPageViewRightClicks = AlwaysDisable (or whatever the syntax is)
Thanks for you help
Cheers

OS X 10.6.8 using MOZILLA Firefox java applet plugin has crashed

Hello everyone!
I am running OS X 10.6.8 with the latest java plugins downloaded via software updates from Apple.
I am using Mozilla Firefox version 28.0.
I wanted to use a website (www.vectis.co.uk) to view a live bidding auction, but everytime I try to connect, it says that my 'java applet plugin has crashed'. I have checked what version of java I have, it is 1.6.0_65 which I believe is the latest version. The minimum requirement according to Vectis is version 1.6.0_35.
I am using Firefox because Vectis states they do not support Safari. My version of Firefox is the latest. When I check the plugins via 'Firefox Tools -> Add-ons -> Check to see if your plugins are up to date' , it says that Java plugin is 'vulnerable' and I should obtain the latest version by going to Apple 'software updates' to ensure I have the latest version of java. Why does Firefox not recognise the latest version of Java plugin from Apple? I believe that for OS X 10.6, Apple provides Java plugin updates and there is no need to dowload anything further, so I am unable to install any other Java applet plug-in because they are supplied by Apple.
Why does the java applet not work??
This is killing me, please help!!
Thank you
Leila

Acrobat 9.31 / Browser Plugin - Printing Color PDF as Black and White?

I have an interesting issue for the masses. For a couple of our users (it encompasses both Windows XP x64 and Windows 7 x64), they are having an issue where when they attempt to print a PDF directly from Acrobat's browser plugin (in this case, IE8 is the browser), and attempt to print a color PDF to a color printer, the PDF comes out in black and white.
Here's some other consistents:
* Printing to a network printer, using the print driver Canon C5180-H1 Ver.2.0JM. The problem spans across two different print servers (we use a different one for XP clients and 7 clients, but the driver is the same)
* When the user clicks on "Print As Image", it does work (but doesn't look quite as good)
* When the user saves the PDF to a file and then opens it in the full Acrobat 9 Pro application, it does work (but this is a bit annoying)
Can anyone suggest some other things I should check and/or reasons that this might be happening? I'm at a total loss to explain it but will happily accept suggestions on ways to fix it.
Thanks!

Following up to see if anyone has some solid ideas on how this might be happening.
Thanks!

Making a java browser component for Mac platform(Urgent)

I was trying to make a simple java browser component from scratch for running on Mac platform. I was using JFrame/JEditorPane. Although JEditorPane can open web pages but it can't support Javascript, flash and other interactive features of many websites. Does anyone know any way to make JEditorPane support javascript?
I also researched on JDIC java web browser, but unfortunately they don't support for Mac yet. Is there any free third party tool available which I can use?
Any quick help is appreciated. Thanks.
