Unexpected end of file from server

[ajse ruku]

Hi all,
I am getting (Unexpected end of file from server)this error when I am connecting to my server via proxy server.
I have done the configuration like this

System.getProperties().put("proxySet", "true");
System.getProperties().put("http.proxyPort", "8080");
System.getProperties().put("http.proxyHost", "192.168.1.34");
URL url=new URL("http://192.168.1.45:8657/someapp/somepage");
URLConnection connection = url.openConnection();

Pls help if anybody have any idea.
with regards,
ajse
