Need help configuring proxy for Java URL connection.

My company has firewall setting. So I am trying to set the proxy manually using:

      System.getProperties().put("proxySet", "true");
      System.getProperties().put("proxyHost", "someproxy.com/....");
      System.getProperties().put("proxyPort", "8080");
         
      System.getProperties().put("socksProxySet","true");          
      System.getProperties().put("socksProxyHost","someproxy.com/...");
      System.getProperties().put("socksProxyPort","8080");

But the someproxy is what I am not sure of. I tried to look up the proxy from my browsers but both are configured to select Automatic Proxy configuration from a url which includes a port number and few paramaters (http://someProxycom:8080/array.dll?Get.Routing.Script)
. I tried to hit the proxy in a browser and it returns me a .DLL file.

Please if you know let me know how to get around this issue as my URL connection fails inspite of using the proxy.
