Get Response Code 200 in windows but get Response Code 401 on Unix

[ABHINAV KUMAR]

Program simply connects to a server and gets back the response from the website.
It is working fine under the Windows XP env. (Response Code: 200, Response Message: OK) but when the same code is run on the
Unix m/c it connects to the website but gets a negative response (Response Code 401, Response Message Unauthorized).

I am using instance of class HttpURLConnection.
There are differences in the versions of java used in both the enviornments.

Win
----
java full version "1.5.0_14-b03"

Unix
-----
java full version "1.4.2_06-b03"

In Unix I tried to ping the website using the ping command.

ping <website>
<website> is alive

Also tried to setting proxy server which my web browser was using in windows

System.getProperties().put("proxySet","true");
System.getProperties().put("proxyPort","8080");
System.getProperties().put("proxyHost","10.196.51.140");

It didnt help either. Is there some Unix enviornment related setting which can be configured in Java.
Kindly advise

Does the proxy require authorization (a username and password)? If yes, then you'll need to set the proxy username and password as well, otherwise the proxy server will tell you you're not authorized.

You can find examples on the web on how to do that:

Thanks Jasper
So I believe its the Proxy server which responds with code 401 , Unauthorized and not the actual website ?
Will get & try using the credentials of the proxy server.

Will it be worth wile to check the headers of the request going from the Unix m/c to the website,
Assuming the website server returns Response code 401 on the basis of the information sent to it in header ?

I'snt there a solution for this ?
