Anyone here know much about Java?

I have user input for a URL field. I want them to be able to enter anything from "http://andrewducker.wordpress.com/xmlrpc.php" to "andrewducker.wordpress.com" and be able to end up at the same end point.

I've wasted a couple of hours messing around with the various constructors for URL and not got to anywhere satisfactory, should I just do string checking and construct it myself?

I should make it clear - I always want the /xmlrpc.php bit to be what's on the end of the URL, that's a Wordpress standard, so I don't need to do any complex discovery. I just need to append that if it's not there.

I was hoping that someone would have written a class that could append bits of URLs together, but the basic stuff in the built in URL class doesn't quite cut it.

Yup. I'm thinking I might be as well off with something like:
if first four characters are not "http" prepend "http://"
if last 10 characters are not "xmlrpc.php" then (check if the last character is a / and append one if not) append "xmlrpc.php"

As that basically satisfies my problem without involving regexes at all, which might be simpler :->

Typically character-index based solutions have all of the brittleness and none of the readability of rexexp-based solutions, but in this case I think your algorithm makes sense.
