Browser and system proxy settings are ignored

[David O'Callaghan]

Binary package hint: icedtea-gcjwebplugin

Package: icedtea-gcjwebplugin 1.0-0ubuntu5
Description: Ubuntu 8.04.1
Release: 8.04

My desktop PC is behind a non-transparent web proxy and I have this configured in my browser and system preferences.

When attempting to load an applet (e.g. from http://www.java.com/en/download/help/testvm.xml) the browser status changes to "starting applet..." but I see only a grey box. The log shows "netx: Initialization Error: Could not initialize applet. (java.lang.ClassNotFoundException testvmDynamicJavaComPopUp819)"

To work around this I set up Squid as a transparent proxy and configured iptables to redirect web traffic to it. When this is enabled the applet loads successfully.

I would expect the plugin to use the system or browser proxy settings for downloading class files. Instead it assumes a direct connection to the web.

works with icedtea6-plugin in the openjdk PPA (and the ca-certficates-java package installed)

Not working for me with icedtea6-plugin from the openjdk PPA or the latest release in Intrepid.

I can't use applets through proxy settings configured in browser/system. I've tested this with firefox in a clean profile in safe mode. It only works if I set up squid as a transparent proxy and set iptables to redirect traffic on port 80 to the proxy. http_proxy env variable is set and proxy is also config'd for Gnome.

I'm happy to supply more information on request.

Tested with:
icedtea6-plugin
    6b12-1ubuntu1~ppa10
    6b12-0ubuntu6

firefox
    3.0.3+nobinonly-0ubuntu2

I don't believe the fix works: see my comment from 2008-11-03.

Any chance what problem with proxy will be solved in 8.04.3 LTS?
