我不熟悉Java，但我需要从我的小应用程序内发出请求到远程web服务。

web服务（.NET 1.1）使用 HttpContext.Current.Request.UserLanguages​​ [0] 来确定要使用的语言。但这个成员的值常是空。

那么，有没有办法通过Accept-Language头以及类似EN-GB设置？

如果这是不够好，你知道的小应用程序运行的系统的默认语言（操作系统），可以从小程序＃的getLocale（）。如果你真的需要preferred浏览器语言，你可以得到它的服务器端的Servlet容器从的ServletRequest＃的getLocale（）和动态生成的小程序标签，传递语言code的小程序作为参数。

I'm not familiar with Java but I need to make a request to a remote webservice from within my applet.

The webservice (.Net 1.1) uses HttpContext.Current.Request.UserLanguages[0] to determine the language to use. But the value of this member is alway null.

So is there a way to pass the Accept-Language header along with something like "en-GB" set?

If it is good enough for you to know the default language (operating system) of the system the applet is running, you can get it from Applet#getLocale(). If you really need the preferred browser language, you can get it server-side in a servlet container from ServletRequest#getLocale() and generate the applet tag dynamically, passing the language code to the applet as a parameter.
