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

Looks like you already figured out the hard part, which is what host your are running on. The rest is easy,

String url = host + request.getContextPath() + "/someImage.jpg";

Should give you what you need.
