For a single request, no.

A server might be able to tell the difference between a browser and Java 
by looking at previous interactions, eg if the browser had made some AJAX 
calls that the Java program did not because it was not running JavaScript.

IME, if i have a Java program and a browser behaving differently, it's 
because the request is different in some way i hadn't realised. Get 
Wireshark on the case immediately, and safe yourself some puzzlement.
