Building an absolute URL from a relative URL in Java

Question

I\'m having trouble building an absolute URL from a relative URL without resorting to String hackery...

Given

http://localhost:8080/myWebApp/someSer         


        

Answer 1

How about:

String s = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath() + "/someImage.jpg";
