Question

I have an application which needs to connect to net. I need some advice when dealing with proxy Connections. Currently the user sets the proxy settings and hence I use the entered information to connect. Is there a better way to deal with such situations.

I mean something like chrome which opens system’s proxy settings and then uses them. How to do it and retrieve those values? Any other Ideal method?

Secondly, currently I am checking if there is a proxy set or not. If yes, I am using url.openConnection(proxy);
IF not then plain url.openConnection(); Is there a more cleaner way of doing it? where system automatically connects with proxy set.

From source code we can use

System.getProperties().put("http.proxyHost", "ProxyURL");
System.getProperties().put("http.proxyPort", "ProxyPort");
System.getProperties().put("http.proxyUser", "UserName");
System.getProperties().put("http.proxyPassword", "Password");

Command Line :

  $> java -Dhttp.proxyHost=proxyhostURL -Dhttp.proxyPort=proxyPortNumber
-Dhttp.proxyUser=UserName -Dhttp.proxyPassword=Password ProxyClassHere
