Java won't work on proxy server!!!!

My company has recently implemented a proxy server. After this, all websites that use java don't work anymore. I have Web Proxy and Web Secure Procy configured correctly but when I enter a Java website I'm asked for user, password and domain, and even with this info the site won't open. Any ideas???

I have the same issue. We have important print production software that depends on Java running in a browser and it has stopped working with 10.5
This means that I cannot deploy 10.5 in a print production environment.
All our web traffic goes through our IIS proxy, and when accessing a Java site I get prompted for an NTLM password. It does not accept any valid passwords, but just re-prompts over and over. The same version of Safari on 10.4.11 works fine with Java as long as all the updates are loaded.
Proxy access in Mac OS X is continually an issue for us, as the current version of Safari cannot access any https sites through our proxy either. I've been forced to install Firefox for users who need access to https sites (which is almost all of them).
We've had issues with our IIS proxy on and off since way back at 10.3 where proxy support would go between working and not working with various patches. This, coupled with the fact that NTLM authentication is much more intrusive on Mac OS (with constant prompting and hassles with the keychain) than on Windows, causes major support headaches for us. I've tried various workarounds with using Authoxy and Squidman, and various keychain settings, but I'd prefer it if the system's built-in IIS proxy support would work better.
It's very frustrating because our IIS proxy has not been significantly changed in over 5 years, but our Macs go from working to not working continually as patches are released. Very poor.
I would love for this to be looked at at Apple, as Mac OS's own proxy panel does not even have as simple an option as "use this proxy server for all protocols" as found in IE on Windows or Firefox on all platforms. This means separate entries in the keychain for all protocols and a huge mess to support.

Java won't work - possible proxy issues?

I was informed that one of our computers suddenly (from what I was told about 2 months ago) developed problems with Java. Said computer is on our dirty internet connection, so it's not readily checked or even updated. My colleagues looked at it, and evertually escalated the issue to me, since they couldn't figure it out. One specific website needs Java for some examinations, and it turned out Java just would present an error to the site.
After spending an afternoon at the location, testing with the Java verification applet on the Java website, and finding myself unable to correct the problem, I build myself a small test machine to see if I could recreate the problem on something local. Turns out, I can, which makes testing a lot easier. Do note: We want another site (which requires a heap of logins) to work, so I'm using the Java verification applet to get me a quicker and easier way to verify if Java works.
So, Got a clean install of Windows XP SP3, and updated to IE8. The machine is connected to the Internet through a proxy server based on FreeProxy which listens to port 2244 (note: this proxy has had NO changes in the aforementioned 2 months that I know of, or can trace within the proxy configuration). I can browse without any problems. Installed Java (7r51) on the system, and tried to verify the Java version.
Unable to verify if Java is installed and activated on your browser.
Ran all the Windows Updates (for XP, IE, .NET whatever version, and whatever more was available) Microsoft offers, just to make sure it's not in any of those. Still no go. Installed Google Chrome and Firefox to exclude the browser as a source of problems. None of the three browsers works with the Java verification applet, all resulting in the same message as stated above. Verified that Java is available in the browsers, and it is shown as available and active.
Deinstalled Java, reinstalled. Used JavaRA to remove and then reinstall. Pulled the security down to medium. Wiped the local cache files. There is no virusscanner installed, so that can't be it. Disabled the Windows Firewall to exclude that as a cause. Used a second machine with Windows 7 just to exclude the OS as a culprit. Verified the 'Enable Java in web browser' setting in the Java control applet. Played with the proxy settings and the security settings in IE and under the Java control panel. Wiped Java out, manually ran through the registry to kill references, and wiped all the Sun folders from all profiles, aswell as the Java install folder before reinstalling. Installed Java 6r43 just to make sure. Nothing helped.. The error keeps coming back, and the Java verification keeps failing.
The Java console which can help troubleshoot, seems to open while the Java icon shows up in the systemtray, but it quite rapidly (30 or 45 seconds) closes again, taking the Java console along with it, thus not giving me any logging to further see what's wrong here. So it seems Java is working, but runs into some problems along the way. About the only quick problems I spotted when I did manage to grab a copy of the log:
network: Cache entry not found [url:http://www.java.com/en/download/JavaDetection_applet.jnlp, version: null]
and
java.io.IOException: Server returned HTTP response code: 403 for URL: https://java.com/en/download/JavaDetection_applet.jnlp
My colleague noted that it did work on the other proxied network through the same proxy (just that that proxy is on a different NIC and listens to port 8080). We tried changing the proxy port for the network to 8080 on the actual PC on location, and found the problem remained. Just to make sure it worked on the other network, I reattached the PC to the other network, altered the proxy settings both under the IE options and Java control panel applet, only to see it exhibit the exact same behavior. So I'm dismissing my colleague, and assuming it has never really worked.
Most of the internet solutions I can find refer to changing the code of the applet, but since I'm using a sanctioned Oracle applet, and Oracle software, I suppose I can assume it's been programmed well, and tested properly. Besides that, as a user of Java I have no direct influence on the actual code being used, so all those solutions aren't really helping me any.
So I turn to this forum to see if anyone wants to have a guess at what is wrong here, and what I can do to either
1) Solve the issue
2) Provide some means to keep the Java console open or log to a file
3) Think of anything I haven't tried yet, that may have a positive impact on the issue.
Thanks in advance for your time, effort and help. Know that every response is already highly appreciated.

Thanks for the response...
I had a look about more logging on the proxy, and although http://www.handcraftedsoftware.org/index.php?page=faq&op=read&id=25 hints at a different program I might need to use (which has been removed of what I can see), the link http://www.handcraftedsoftware.org/index.php?page=faq&op=read&id=54 hints at there being some native logging I can use to verify what happens.
As such I located the log settings, and fired up the test system to see if I could determine some more from the logs (and exactly what those logs would entail). The log does provide some insight in what it pulls from the Java website, but doesn't show much in regards to what is going wrong:

At around that same time I got the following notice in the connection log, which does seem to hint at a problem somewhere:
#11004: WSANO_DATA: Valid name, no data record of requested type. H:02424 F:'HCSNTSocket_ResolveHostName' A:'gethostbyname' T:'Return=11004.'
Other then that I have not received any other logs (despite me enabling all of them, or any other notice that may indicate the cause of the problem. I will be leaving the settings in the proxy in regards of logging, just to see if any other logs are going to crop up.
I did post this to the Proxy-forum too to see if someone could help in determining what exactly the log is saying.

FF 16.0.2 won't work with proxy server

My school district requires using their proxy server. Suddenly FF 16.0.2 no longer will connect to the proxy server, despite all settings configured correctly in System Preferences. Firefox prefs are set to "use system proxy settings". I've also tried Manual proxy settings, and Auto-detect proxy settings for this network. All of those options used to work just fine.
I CAN successfully connect using Safari 6, so it's not the proxy server itself (Safari only uses the System Preferences proxy/network setting).

Local users work and I have even tried giving a standard domain user both local and domain admin rights as a test to see if that would work but sadly not.
Please has anyone seen this before as I am completely stumped now, I have been through all group policies on the server and can't find anything that would interfere with java in such a way
I have even tried removing the deploy policy for java, uninstalling it, running ccleaner reg fixes and then installing it straight from the website with no luck
Thanks in advance for any help offered,
Adrian

fromg googling it might have something to do with messed up fonts. I can get firefox to work as root though! 0_o.

Just an idea: Have you tried to use Firefox from Mozilla. I mean, download it and give it a try?
I have always done that, from my days in Slack, till this day and have to say that I NEVER have had a problem with Firefox, Java or plugins.
It may be a very biased opinion (since I have never had problems) but I think it may be worth to try.

Java won't work on Firefox, while it works on Safari on a Mac.

I have a MacBook Pro and downloaded Firefox 3.6 for it. Now I've realized that Java plugins won't work in Firefox for some reason, while they do work in Safari that came with the Mac. The problem wouldn't be with Java, since it works on Safari.
The Java-related plug-ins I have installed in Firefox are the Java Embedding Plug-in 0.9.7.3 and Java Plug-in 2 for NPAPI browsers.
When I go to a page that contains a Java applet, there is no error, the page says it's done loading, and there's a blank spot where an applet is supposed to be.

Actually, I have both plugins installed in Mac OS X 10.6, verified by entering '''about:plugins''' in the SeaMonkey 2 Location Bar (address bar)
Java Embedding Plugin 0.9.7.3
<br>File name: MRJPlugin.plugin
Java Plug-In 2 for NPAPI Browsers
<br>File name: JavaPlugin2_NPAPI.plugin
This is a new iMac computer I just set up last week running OS X 10.6.4 with all current Apple Software Updates. I have SeaMonkey 2 installed on it, but not Firefox.
I have Java 6 Update 20 ( 1.6.0_20 ) installed, verified by going to the test link in the KB article I posted above,
http://javatester.org/version.html
Java 1.6.0_20 (referred to as "Java for Mac OS X 10.6 Update 2" on the page cor-el linked) should be available from Apple's [http://support.apple.com/kb/HT1338 Software Update] feature.
Another test link you can try (from about:plugins):
http://browserspy.dk/java.php
I think that the Java Embedding plugin is something that Mozilla includes with all its current browsers (Firefox, SeaMonkey, Camino) based on: http://plugindoc.mozdev.org/OSX.html#Java
...which links to http://javaplugin.sourceforge.net/

Java doesn't work in proxy environment

I assume it's because of the "separate process" approach to running Java taken by Safari 5.1, but when my system is set to use a proxy, Java ceases to function in Java 5.1. If I then return to a non-proxy environment, Java works again. In the proxy environment I tried reinstalling Java and quitting and relaunching Safari, but no luck. Under the same conditions the same Java applets worked in Firefox 5.01 so I know Java was fine with the proxy itself, it's just that Safari 5.1 is somehow interfering with that or failing to set a parameter in the Java environment I would guess.
Tried to find a way to lodge a bug report but this is the best I could do.
Anyone else?
Cheers,
Matthew.

Sorry - I meant "in Safari 5.1" and I now see there have been other reports.

Mac Appstore not working through proxy server

I use net through proxy server of my college(lan). My Appstore doesnt work on it. it keeps blinking or shows "cannot connect to appstore". GoogleChrome and other apps are working fine. Also, appstore worked at my home where i use wifi.

That's right. It doesn't work through a proxy.

Local EPM Excel Connection not responding when working with proxy server.

Hi All ,
We were working on a server . Due to some issues we had to use proxy server to connect to the Backend.
But the Local Connections that were made in Excel to log in via EPM Tab is no more working.
Is it something related to Proxy Server.
In that case , how to configure the Local Excel Connections.
Regards,
SHUBHAM

Hi Andy ,
When we connect to EPM Office Add in link in Web Admin , We get basically 3 options, out of which we choose connect EPM Office Add-in for Excel. But that option is not coming. Rather it asks to install EPM addin, while it has been already installed . This problem has been present for a very long time .
So in case of Connecting to Excel Interface , if this option was fine then we could have easily gone to System generated link in Web Admin to connect to EPM Excel interface. But since this option isn't coming so we had to go through making Local Connections.
But given the Proxy server settings the earlier Local EPM Excel Connections are not working.
Regards,
SHUBHAM

Won't connect: "The proxy server is refusing connections." Why? How do I fix it?

I am not a computer person--the machine is a super typewrrriter and research aid; like an auto, it should just run when you buy it. But. I got a virus; tried my amatuer best to correct or fix things. The computer runs now, but will only access Internet Explorer, and Firefox is my browser of choice. Now when I click on Firefox the opening screen starts, then carries the message: "The Proxy Server is refusing connections."

In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".<br />
See "Firefox connection settings" in [[Server not found]]
You can find the connection settings in Tools > Options > Advanced : Network : Connection<br />
If you do not need to use a proxy to connect to internet then select No Proxy

Java won't work on safari

I believe it is java thats not working. I use a website called mathzone.com and when i go on there to do my work safari wont pull up the interface for me to see the questions or to put in the ansers. If I use another browser like firefox it works fine... I just prefer safari. does anyone know how to help me.

Click here > http://mpss.mhhe.com/products-mathzone.php
Then click: Check your browser for plugins
The site requires Shockwave, Flash, QuickTime, and Real Player.
And make sure Java is enabled in Safari > Preferences > Security.
Much better off using Firefox for this particular site. Safari has incompatibility issues with RealPlayer.

Flash Builder plugin for Eclipse (Java) won't work

I have installed Flash Builder Premium and then ran Plugin Utility to plug it into an existing Eclipse install. Now when I start my existing Eclipse, I see this error in logs - "org.eclipse.equinox.p2.core.ProvisionException: No repository found at file:/C:/Program%20Files%20(x86)/Adobe/Adobe%20Flash%20Builder%204.6/.". I have Flash Builder Premium 4.6 installed at "C:\Program Files (x86)/Adobe/Adobe Flash Builder 4.6".

Just to add to it (if it helps) - I'm able to run Flash Builder in standalone mode with Eclipse version that comes with it. However, the plugin into my existing Eclipse(3.7.2) won't work. Any idea what could be the problem?

After installing 10.9.2(Maverik), Java will no longer work. I went to the java site and downloaded. However, the new java won't work with maveric either. What do I do?
