Java not respecting system proxy settings.

Trying to launch a webex session in Safari (Version 5.1.2 (6534.52.7)) from behind a corporate VPN, but is failing with

network: Connecting http://oraclesystemsupport.webex.com:80/ with proxy=DIRECT
It seems it can't load the class because it's trying to connect DIRECT and not via my corporate proxy.
My proxy is configured in my system settings as "auto proxy discovery". Everything else honours the proxy setting. Safari has no problem and connects to all internal & external sites without issue. Even Firefox has no problem, and can launch the webex fine. If I configure a proxy ipaddress in the "Java Preferences" network proxy settings, I can launch the webex. But when set to "use system settings", it doesn't use the proxy.
So I can't figure out why java, when launched through safari, doesn't respect the system proxy setting.
I know it's nothing to do with local caching because I get the same with a fresh user I created especially for testing.
Has Apple broken something?    It was working fine until I applied the latest updates last week.

It seems to be an issue with 'liveconnect' (which I assume is needed by webex).
liveconnect can be tested here.
http://www.jdams.org/live-connect-test/
The above test works fine when a proxy isn't involved. But on the corporate VPN liveconnect get stuck trying to connect DIRECT instead of going via the proxy.
Is this a known bugs? any ideas?

Safari does not using system proxy settings (charles web proxy)

Using OSX 10.7.3 and Safari Version 5.1.3.
I start Charles, the web debugging proxy. On start, Charles adjusts the proxy settings in the Network Panel of System Preferences as expected. But Safari does not / will not honor these settings.
Has anyone else had this problem?

You have to apply the change before it takes effect.

"Use system proxy settings" Not working on Mac OS X Snow Leopard

When I change the network location or when I select "Use system proxy settings" on the connetion configuration dialog.
Firefox is not using the proxy defined on the loction set on Mac OS X Snow Leopard.
I usualy change from work to home, at work I've a proxy and at home I don't, and it's a bit annoying to have to change the proxy twice a day. So I tryed this feature, but It's not working for me.
I've tryed also with Firefox 3.6 (I think) and didn't work either.

I run it from eclipse, and on debug mode i checked the value of
java.library.path, and it was ok.
Any way, how can i do what you suggested on mac?It's just a command line argument, but there's no reason to add it if your
java.library.path is ok. One of its componenents must be a directory where
your shared lib is stored, that's all. BTW, the Mac is unix based isn't it?
Shouldn't it be an .so file then? (just a wild guess)
kind regards,
Jos

Windows - Use system proxy settings not working as expected

Hi everyone,
I have a bit of an issue that I could use some help with. We currently have remote users that utilize an SSTP VPN connection to access our internal network. Once connected, those users are required to use an internal proxy server to connect to the Internet. The proxy server is Microsoft's TMG and utilized domain authentication.
On our remote Windows clients we have their Internet Options configured to utilize a proxy as follows:
Internet Options -> Connections -> LAN Settings -> No proxy configured at all
Internet Options -> Connections -> Highlight SSTP Connection -> Settings
Use a proxy server for this connection -> IP/Port of Proxy Server
Firefox and Chrome are both configured to use system proxy settings.
Here is my process to demonstrate the issues:
Remote client workstation is rebooted.
With the above configuration just after a reboot, a remote user that is not connected to the VPN can browse the Internet with Internet Explorer, Chrome, and Firefox. None of the browsers prompt for credentials.
A remote VPN connection is then established.
FF is opened and HTTP connections utilize the proxy server. However, HTTPS connections do not use the proxy server, but instead attempt to use the default gateway. FF does not prompt for credentials. FF is closed.
Chrome is opened and can access both HTTP and HTTPS sites without issue. No credential prompt. Chrome is closed.
IE is opened and can access both HTTP and HTTPS sites without issue. No credential prompt. IE is closed.
Here's where it gets weirder...
FF is then reopened. The VPN connection is still up. FF will prompt for credentials. Domain credentials are supplied and FF can now utilize the proxy for both HTTP and HTTPS connections. FF is closed.
VPN is disconnected.
FF is opened and cannot access the Internet as it is still trying to use the proxy server. FF is closed.
IE is opened and can access the Internet. IE is closed.
Chrome is opened and can access the Internet. Chrome is closed.
FF is reopened and can now access the Internet. FF is closed.
In summary, in the above scenario FF acts in an unexpected manner with regards to proxy usage when "use system proxy settings" is applied. However, Firefox begins acting as expected after IE is opened and closed. For example, connect to VPN, open IE, close IE, open FF, and everything works accordingly. Disconnect the VPN, open IE, close IE, open FF and everything works as expected.
Any insight you can provide would be appreciated as it is affecting our FF users and the sooner we can achieve resolution the better. As a note, we've also worked through this issue with WPAD and proxy auto-detect. I've intentionally removed these from the equation to simplify troubleshooting.
Thanks

Quick update. Added to a previously filed bug. Looks like it's assigned now so maybe we'll see a fix for this soon.

Firefox not detecting/using system proxy settings

I use a command line script to change among various proxies (and none). Firefox does not recognize when a proxy is turned on or fails to connect to it (no error messages), while other browsers and applications do just fine.
I have tried selecting "Use system proxy settings" and "Auto-detect proxy settings for this network."
My script contains these lines to activate a proxy
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" /v DefaultConnectionSettings /t REG_BINARY /d 46000000b10000000200000014000000736f636b733d3132372e302e302e313a313131311c0000002a2e6c6f63616c3b3139322e3136382e31312e2a3b3c6c6f63616c3e000000000000000000000000000000000000000000000000000000000000000000000000 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v MigrateProxy /t REG_DWORD /d 1 /f
The first line enables the proxy to take effect without entering inetcpl.cpl. Again, this works for any application other than Firefox.
The proxies are all through ssh with port forwarding.
I do not want to manually configure a proxy in Firefox, because I do not want to change this every time I need to change proxies or turn them off. This is not an acceptable solution.
I am on Windows 8.1 64bit, with Firefox version 35.0
Any idea what might be going on here?

Thank you for the response, but as above, the "Auto-detect proxy settings for this network." setting does not work.

System Proxy Settings only work as root

Using Firefox 10.1 on Suse Linux Enterprise Edition 11 SP2
Setting the System Proxy settings to our Proxy and using Firefox with "using System Proxy Settings" works as root user. The Authentication Prompt for Authentication Pops up and after entering the credentials FF works.
The very same Settings do not work as non-root User. Not even the Authentication Prompt for Proxy Authentication pops up.
All Proxy Settings are available too both users (checked Variables exported in Shell).
Any Pointers appreciated.

Yes, entering the Proxy settings manually does work. Even the automatic configuration using the proxy.pac works. Just the "Use System Settings" part does not.

Use System Proxy Settings - when this is selected in FF v3.6.6, does it adhere to the same local IE proxy setting? We use a pac file configured in "Use automatic configuration script."

Does anyone know what Firefox looks at locally on the PC when the "Use System Proxy Settings" setting is selected? It appears to be the default setting, recently changed from "No Proxy" of versions past...
Our company uses a pac file specified in IE under "Use automatic configuration script" - with this new default, does it adhere to the same setting in:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

I may be wrong but I think that the "Use System Proxy Settings" makes sense only on Linux and generally speaking "other OSes". As far as I know there is no generic proxy settings in Windows operating system.
The one I know is in the registry part of Internet Explorer.
So in my understanding in Windows, Use System Proxy Settings = No Proxy

PowerShell 4.0 ISE doesn't use the system proxy settings

I can retrieve the contents of a URL using something like 'iwr
http://www.adobe.com' in the command-line PowerShell host.
This takes into account the proxy settings in Control Panel / Internet Options.
If I attempt the exact same thing in the PowerShell ISE, I get:
iwr : The remote name could not be resolved: 'www.adobe.com'
This works only if I add the -Proxy and -ProxyUseDefaultCredentials options.
How comes?
How do I fix this?

I hate to say, but I don't understand how what I see is compatible with your statement.
Let me show what I'm experiencing with more details.
Here's what I get without any proxy options from powershell.exe:
PS 4.0 ~> $r = iwr http://www.adobe.com
PS 4.0 ~> $r -eq $null
False
PS 4.0 ~> $r.GetType()
IsPublic IsSerial Name                                     BaseType
True     False    HtmlWebResponseObject                    Microsoft.PowerSh...
and here's what I get from the ISE:
PS ~> $r = iwr http://www.adobe.com
iwr : The remote name could not be resolved: 'www.adobe.com'
At line:1 char:6
+ $r = iwr http://www.adobe.com
+      ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-W
   ebRequest], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebR
   equestCommand
PS ~> $r -eq $null
True
If the CmdLet requires the -proxy option, how do you explain the results I get without the option from powershell.exe?
Next to that, here's what netsh reports:
PS 4.0 ~> netsh winhttp show proxy
Current WinHTTP proxy settings:
    Direct access (no proxy server).
This is not what I have under "Internet Options", where "Automatically detect settings" and "Use automatic configuration script" are both checked. But IIRC from the proxycfg.exe days this reports the "system-wide"
proxy settings, not the per-user proxy settings.

Safari not adhering to proxy settings

I'm a new Mac user, so bear with me if I'm missing something obvious...
I am attempting to use Safari through a proxy, while connected to a VPN. However, after setting the proxy values within the network settings, Safari still does not attempt to send traffic through the defined proxy. A tcpdump on the proxy server confirms that no traffic is inbound to the proxy from my IP. Using the same proxy settings in firefox, I can connect just fine.
Any ideas?

I am having the same problem and some insights will be appreciated. I did notice one thing, though.
If I set my proxy, then connect using the VPN, it seems to pick up the proxy setting. Similarly, on disconnect, I unset my proxy and then disconnect and safari picks up the new settings. If I do not do things in this order then I get into a situation when either Safari thinks there is no proxy when one has been set or, worse, thinks that it should be connecting to a proxy when there is none.
This seems to indicate that there is some kind of cache of proxy information in Safari which is cleared on the VPN connect and disconnect.
Any way around this issue will be much appreciated.

Firefox does not retain my proxy settings.

Everytime I launch the browser I have to reset the proxy settings in order for it to work. I don't use a proxy but Firefox seems to think I do and assumes that i use some random proxy that it populates. I don't have this issues with other browsers so its not my connection settings.

I have the same problem and have tried all those things. I have also tried deleting the Firefox profile and restarting. I have also tried reinstalling and not adding any addons. I have even removed Firefox registry keys and any Firefox files left by the uninstall before attempting to install it again. No matter what I do, Firefox begins to stop retaining any history. This all started when I upgraded to 4.0. It is frustrating because I have seen all over the net that others are having this problem. I backed up to the 3.6 version and that fixed the problem. After a while, I decided to go ahead and go back to 4.0 to see if the issue would stop. But it does it again!

System proxy settings GNOME

Am behind a proxy server and am having a problem configuring system-wide proxy settings in a gnome environment. All I have been able to do is export the proxy setting on the terminal to be able to use pacman. How do I supply these settings to all other applications for instance empathy? I also couldn't help but notice the missing 'apply-systemwide' button in gnome-control-center under proxy preferances( I used to do this in Ubuntu).
Thank You.

Youtube not working on proxy settings over wifi

my university wifi has proxy server.........therefore requires proxy settings on my iphone,
after the seetings are changed, the youtube videos do not stream at all.......but the safari is fine!!! and even the mails dont open up
any suggestions.

Proxy servers can be used multiple ways - like protecting your identity behind a proxy server, managing network traffic, limiting access to certain websites...
Contact your uniniversities IT deparment for help on this one. They may have special configuratioin settings that you need to use.

Cannot log in. Get error message proxy server not reponding, check proxy settings. How can this be fixed ?

I get the following error message:The proxy server is refusing connections Firefox is configured to use a proxy server that is refusing connections. * Check the proxy server

You may have a problem with an extension if you do not keep settings.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

My Applet not running in java not installed systems.

dear sir/madam,
i have an applet which uses java.awt.* and java.awt.event.* classes, is running in systems with J2SE installed. but it is not running in systems with java enabled browsers without J2SE installation.
i want my applet to be run in all java enabled browsers without J2SE also.
how to make my applet work.
thanks in advance.
-- ks_moses

install J2SE to develop Java programs..
install JRE to run your Java Programs
To run your applets into such a browser, you must have a plugin installed on that browser to run your applet, so install JRE(Java Runtime Environment), it will install the Java plugin automatically so you can run your applets, GoodLuck
