Subject RE: Auto-detecting proxy settings in a standalone Java app

Hi Chris,

You may also want to take a look at the plugin.jar that ships with the JRE.
You'll find some good stuff in sun.plugin.net.proxy.WIExplorerProxyConfig.
Here are the registry entries that Sun looks for in that class.

    private static final String REGSTR_PATH_INTERNET_SETTINGS =
"Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings";
    private static final String REGSTR_VAL_PROXYENABLE = "ProxyEnable";
    private static final String REGSTR_VAL_PROXYSERVER = "ProxyServer";
    private static final String REGSTR_VAL_PROXYOVERRIDE = "ProxyOverride";
    private static final String REGSTR_VAL_AUTOCONFIGURL = "AutoConfigURL";


There are also proxy detection classes for other browsers in the same
package.

Bruce.

Hello Chris,

setting a fantasy proxy server in IE and searching for it in the registry 
yields:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet 
Settings
-> ProxyServer
-> ProxyEnable


a quick search on Google for "Java Windows Registry" yields:

http://www.trustice.com/java/jnireg/
A public domain solution to access the Windows registry.

http://sourceforge.net/projects/jregistrykey/
An LGPL-licensed solution to access the Windows registry.


hope that helps,
  Roland

Re: Auto-detecting proxy settings in a standalone Java app






Hi,

Thanks for all the rapid feedback so far.

I don't have VB or the VB runtime, although perhaps I could use the 
JNIWrapper software to access this information (if I knew where it 
was...!). 
  Pity the Webstart proxy detection stuff isn't available for all to see, 
as 
it returns (I think) appropriate params, whether you use IE or Mozilla or 
whatever.

On the other hand, given that JNIWrapper is commercial software, perhaps 
someone would know how to write a simple C program with "mingw" or 
whatever 
(easy to compile).  It could detect params and return them on STDOUT, to 
be 
picked up either by a startup.bat or even through Runtime.exec() (solving 
the "restart the JVM" problem discussed earlier in this thread).

First thing's first though... does anyone know where this information is 
stored in Windows ?  IE and Mozilla/Firefox seem good targets for 
starters.

Hey, why not even a little optional subproject for HTTPClient (requiring 
JNI 
and a compiler, preferably not *requiring* the MS tool chain), with a 
simple 
ProxyDetector interface, and a series of platform-specific implementations 

(to go further than my current Windows-only need) ?

Any thoughts on these big ideas, or at least as far as solving the 
immediate 
problem (where are these settings stored and how can I get at them?)

Thanks to all,
Chris
