Firefox allows Java Applet with elevated permissions

I ended up with a virus on Friday when I selected "View" on an HTML attachment from the GMail web interface. The attachment started up java and proceeded to install the malware "Desktop Security 2010" and make changes to my system startup. I'm wondering how this happened and how to prevent it. My java security settings (Java Control Panel->Security->Certificates->Trusted Certificates) only lists Akamai Technologies and JavaFX as trusted certificates. Shouldn't that mean that I get prompted if any one else signs an applet that tries to run outside the sandbox? What else do I need to do to make sure that NO java applets run with elevated permissions?
I've disabled java via an add-in in the meantime, but what do I need to do to secure my browser properly?
== This happened ==
Just once or twice
== I selected "view" on a virus-infected email attachment in gmail

Хорошо. Am now able to enter Cyrillic font into my applet. HOWEVER, another issue remains: After pressing enter to process input, new window opens as expected with correct information displaying in window EXCEPT for drop-down menu bar that should display in green square of open window. http://www.lesbaileyev.com/Project/RFvstem.html I will open another suport question for this new development.

When using Java Wizard with Firefox 3.6.23 on a Mac OS X 10.6.8 it keep getting an error message: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem." Have NO idea how to fix this problem.

When trying to upload files I received the following error: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem."

If the problem is with a site that is hosted using MOVEit DMZ by Ipswitch, please notify the site owner of the issue and ask them to apply the patch that is available on the support site to resolve the issue.
This is a better resolution than downgrading your version of Java that was updated due to security issues.

After downloadeding the latest Java plugin, I start to receive "Please configure your browser to allow Java applets to access the filesystem" message when I try to run a download wizard. What do I need to do? BTW, IE does not have this problem.

I had no problem using a download wizard Java applet to download file to my computer from an SFTP site using Firefox. When I tried to do the same thing with Chrome, I was told to download the latest plugin. Once I did that, I receive the following message when I run the downlaod wizard:

How to start java applet with netbeans 6.1

hey,
I want to learn how to start java applet (with database) with netbeans.. I'm new to java...can you show me how can i start..if you have any doc about it can you send it to me..thank you..:)

You really should be asking this NetBeans question at the NB site - these forums are for Java language topics, not NB support.
[http://www.netbeans.org/kb/61/web/applets.html]
Almost any NB question you have can be answered by either the NB web documentation or the NB program's Help.

Java Applets with AWT

Hi,
I have the problem to display the applet with AWT. If I am running the same applet in the internal server it works fine.If I am running through the web its giving Class not found exception.That web server also is mapped into the same server.
Here is the code.
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class NotHelloWorldApplet extends Applet
public void init()
     try{
          setLayout(null);
          Label label1= new Label("Hello World!");
          label1.setSize(200,200);
          add(label1);
     }catch(Exception e){System.out.println(e);}
<html><body>
<applet
code="NotHelloWorldApplet"
codebase="."
width=600 height=400
>
</applet>
</body></html>
can anyone help me please.
Thanks

Hello,
Even I executed the program. Its works fine. I guess you must be having problem with the codebase. Just change the address in the codebase from current directory to the address where the class file is there and also change the permissions(set attributes to 755) of the class file. Hope this helps you.

Problem Launching Java Applet with Plug-in: Version 1.4.2_01

Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,

Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

Hi Mike,
I see this in your logs:
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS
Proxy Configuration: Manual Configuration
Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
Proxy Overrides:
I just helped my Dad set up his computer with a new
cable modem, and had the situation where we couldn't
access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?

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.

I've read, that Applet can only connect localy. But for example jIRC works also http://www.jpilot.com/java/irc/demo.html ...
How can I manage that?

You get a java signing cert (like from Verysign) - when you sign the applet according to their instructions, it allows the end user to specify if your applet has rights or not, if they say yes, you would have the ability to connect to other servers.
If you want to avoid this problem, make your program an application instead of an applet.

Starting an Java-Applet with https

Is it possible to start a java-applet
from a secure web-page?
https://..../applet.html
If yes - HOW?
null

My code looks something like this
StringBuffer queryString = new StringBuffer(Applet.getCodeBase().toString());
// append all the variables I need here
URL dataUrl = new URL(queryString.toString());
BufferedReader br = new BufferedReader(new InputStreamReader(dataUrl.openStream()));This works from both http and https The protocol is the same as the how the page itself was loaded.

Firefox runs Java applet if in an html file, not if in xhtml file. Google Chrome, and previos version of Firefox OK. Firefox is 13.0.1, Java is 1.6.0_12

Applet is signed, but signature not verified. Firefox should ask permission.
If applet is in an html file, permission is requested and all works OK.
If applet is in an xhtml file, it is not recognised. Changing the file extension from xhtml to html restores correct working (but I do need to run these files as xhtml, so that does not solve the problem!)

Your Java is very out of date, so please update to Java 7 update 5, and test again.
Then, try Resetting Firefox. [[Reset Firefox – easily fix most problems]]

Adobe Flash Player 9 was previously installed with elevated permissions

I have had to disable flash on our websites in order to make
them useable. Looks like flash 9 was updated yesterday and now pops
up a dialog asking to be reinstalled with admin privs. Considering
no one on aprox 250 machines has admin privs, I am now faced with
the task of spending 15 minutes installing and or upgrading flash
on 250 pcs.
THIS IS NOT ACCEPTABLE. what kind of QA did you do on this
release, because im pretty pissed right now.
I have tried the fix located here: (
http://dontpokebadgers.com/axaa/
) which approves the classID, but this does not seem to work. I am
sure other people must be experiencing this issue. I require you to
perform one of the following actions:
1) Provide a method to disable auto updating the flash active
x control
2) Provide group policy settings that will enable seemless
installation in the background. This would ideally be registry
based and not have anything to do with an MSI file that I would
need to bundle into a startup script.
3) Roll back flash to a working version that does not have
this horrible bug
4) Silently fail to update flash, as the old flash still
renders the content after the error message has been cleared.
Please respond ASAP. I am sure you are about to get a flood
of complaints as you have now changed the default behavior of the
flash player, which unfortunately, much of the internet now
uses.

There already is a method for disabling auto-update, as well
as control over many other options for your users... So this isn't
a bug at all. This is auto-update doing what it's supposed to do.
As the network admin you have to disable it.. Read on...
First, as a network install you should be using the (free)
licensed distribution version of Flash Player. The licensing is
here:
http://www.adobe.com/licensing/
That will get you EXE installers for your network if you want them.
Most importantly it gives you the legal ability to distribute the
player and then control it using the following....
Flash Player Administrator's Guide:
http://www.adobe.com/devnet/flashplayer/articles/flash_player_admin_guide.html
Also please keep in mind that these forums are not official
support channels. They're peer-to-peer support. So in the future
please go through
http://www.adobe.com/support/flashplayer
for needs such as this. We do offer support to network admins
supporting the install...

java applications.
at last you can launch your applet by appletviewer.exe
The ONLY purose of applets is to launch it by browser to make this techlology looks like a "web".
Now browsers have no embedded JVM or have outdated JVM (so, "applet" techlology is dead) and you must install proprietary JVMs like Oracle JInitiator.
It much more simple to install a standard JRE in all clients and make just a shortcut to your application.
I think, all computers will have JRE or JDK installed by default.
If you need to use Oracle Forms and JInitiator - it is a proprietary technology and you can ask Oracle support.

Safari for Mac, webpage with Java applet, drag and drop area not working.

At my company, we have a web page that our users access to submit media files, (QuickTime, Audio, images...), for transcoding for delivery. The web page consists of a java applet, with an area that our users drag and drop media file into.
After updating to Safari 5.1.2, the applet will not work anymore. Instead, the browser will "open" the quicktime and play it, instead of allowing the Java Applet to do it's job.
CAN I TURN THIS FUNCTIONALITY OFF??
I read that Safari 5.1.2, (when it was initially released), broke something with the THEN current version of Java, and everyone was awaiting the latest update (build 1.6.0_29) to fix it. Unfortunately, this update did not fix my issue with the functionality of dragging and dropping media files into the web page.
It seems to me, as if, there is an over-arching functionality setting (or something) that needs to be either turned off, or in some other way DE-prioritized.
Anyone have any ideas?

Thanks for quick reply and help. I am able to drag multiple files but this is giving problem in case of filename with spaces like "abc def.png". Can you please put some thoughts on this.
DataFlavor uriListFlavor = new DataFlavor("text/uri-list;class=java.lang.String");
