Hello Chris, native Windows applications "just work" because they access native Windows APIs to read the proxy settings, which are probably stored somewhere in the Windows registry. Browsers and the Java Plugin for browsers are native Windows applications, and therefore can do just that.
The only solution I can imagine right now is for you to write JNI code that looks up the appropriate keys in the registry. Which means you'll have to distribute a DLL along with the Java application. Wait, here is another idea: you could write a startup script that does the proxy settings lookup, then passes the settings through -D definitions as system properties, which can be accessed by your Java application. That's a bit less ugly than calling native code from within the app. The proxy settings for the HttpURLConnection of the JDK are expected as system properties, too. hope that helps, Roland "Chris Brown" <[EMAIL PROTECTED]> 22.10.2004 10:18 Please respond to "Commons HttpClient Project" To [EMAIL PROTECTED] cc Subject Auto-detecting proxy settings in a standalone Java app Hello, I would like to perform a simple request against a HTTP server in an application that will be deployed to customers with a wide variety of network configurations. The application won't be deployed as an applet or within Java Webstart, but will require JDK 1.4.2+ as the platform. The target audience are all Windows users. I've searched the HTTPClient archives and also the forums on Sun's Java Developer site. The only useful links were: http://forum.java.sun.com/thread.jsp?forum=30&thread=364342 http://www.mail-archive.com/[EMAIL PROTECTED]/msg05349.html I get the following error when trying this out: java.io.IOException: Proxy service provider is not yet set at com.sun.java.browser.net.ProxyService.getProxyInfo(ProxyService.java:40) ...so I assume this only works within Webstart or an applet. Is there any way I can *automatically* retrieve the user's browser settings, even if requires using JNI or JNIWrapper for example ? At least the proxy host and port, even better if it can automatically enable login (or even provide me with enough info to use the NTLM features of HTTPClient, if required by the customer's environment). Manual proxy configuration generates *way* more support costs at present than anything else in the project. It's annoying to be disadvantaged in this way, when most native Windows applications "just work"...
