Today I had a trouble in my workplace when a client application, running through a terminal (DOS prompt), not reach the server hosted in the internet, this is because the company where I work use proxy.

After some tries I found two solutions to solve my access problem: first was pass as Java parameters the proxy’s configurations.

$ java -Dhttp.proxyHost=serv -Dhttp.proxyPort=port -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass  ClassJava

-Dhttp.proxyHost = IP or host name of server proxy
-Dhttp.proxyPort = Proxy port
-Dhttp.proxyUser = User
-Dhttp.proxyPassword = Password

This way the class ClassJava will have access to internet through proxy server.

Another way, was insert the settings in own class:

public static void main(String[] args){
...
System.getProperties().put("proxySet", "true");
System.getProperties().put("http.proxyHost", "serv");
System.getProperties().put("http.proxyPort", "port");
System.getProperties().put("http.proxyUser", "user");
System.getProperties().put("http.proxyPassword", "password");
...
}

proxySet = Connect, or not, through proxy server
http.proxyHost = IP or host name of server proxy
http.proxyPortt = Proxy port
http.proxyUse = User
http.proxyPassword = Password

Using this resource you can set your application to access the internet through proxy server.

I hope help you.  Bye!
