From d16944552990c2c953fdbd5e8d11f43e31dcbb3f Mon Sep 17 00:00:00 2001 From: Omair Majid Date: Thu, 27 Jan 2011 12:56:40 -0500 Subject: Use Firefox's preferences to determine proxy settings for javaws This patch adds support for finding, parsing and using basic information from Firefox's preferences to determine the correct proxy to use for javaws. Only the preferences from Firefox's default profile are used. Support for PAC, System or Automatic settings is not yet implemented. 2011-01-27 Omair Majid * netx/net/sourceforge/jnlp/resources/Messages.properties: Add RPRoxyPacNotImplemented, RProxyFirefoxNotFound, and RProxyFirefoxOptionNotImplemented. * netx/net/sourceforge/jnlp/runtime/JNLPProxySelector.java: Make abstract. (getFromBrowser): Remove implementation; make abstract. * netx/net/sourceforge/jnlp/runtime/JNLPRuntime.java (initialize): Set BrowserAwareProxySelector as the proxy selector. * netx/net/sourceforge/jnlp/browser/BrowserAwareProxySelector.java: New file. This class extends JNLPProxySelector and searches the browser's configuration to load additional proxy settings from. * netx/net/sourceforge/jnlp/browser/FirefoxPreferencesFinder.java: New file. This class looks into the browser configration to find the preferences file for the default firefox profile. * netx/net/sourceforge/jnlp/browser/FirefoxPreferencesParser.java: New file. Parses the browser's preferences and makes it available through a simpler interface. --- .../jnlp/browser/FirefoxPreferencesParser.java | 155 +++++++++++++++++++++ 1 file changed, 155 insertions(+) create mode 100644 netx/net/sourceforge/jnlp/browser/FirefoxPreferencesParser.java (limited to 'netx/net/sourceforge/jnlp/browser/FirefoxPreferencesParser.java') diff --git a/netx/net/sourceforge/jnlp/browser/FirefoxPreferencesParser.java b/netx/net/sourceforge/jnlp/browser/FirefoxPreferencesParser.java new file mode 100644 index 0000000..1f206a9 --- /dev/null +++ b/netx/net/sourceforge/jnlp/browser/FirefoxPreferencesParser.java @@ -0,0 +1,155 @@ +/* FirefoxPreferencesParser.java + Copyright (C) 2011 Red Hat, Inc. + +This file is part of IcedTea. + +IcedTea is free software; you can redistribute it and/or +modify it under the terms of the GNU General Public License as published by +the Free Software Foundation, version 2. + +IcedTea is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
