Iam unable to post the data to the server, getting error as . But it is working fine in curl script.
Error reading URL

Do iam doing anything wrong from the above code? DO i need to use curl script to post the data?
Well, as Error 415
is already stating:
415 Unsupported Media Type
The request entity has a media type which the server or resource does not support. For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format.
Without knowing the specifications of what the server is expecting of you to send him, it's hard to tell what you are missing. It though seems as if you only want to receive data from the server and not send him anything.
By setting uc.setRequestProperty("Content-Type", "application/xml");
you tell the server that you hand him over some XML data (which you don't) and he probably also wouldn't expect this, so he's giving you that error.
As your sending some urlencoded data in your POST data, try setting this to:
uc.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
