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.

I think you'll need to add an (s)* to cope with the https possibility.

I for one find your use of * in place of ? surprising. A hangover from pre-PCRE regexes?

I just simplify matters for myself by not bothering to remember what ? does unless I actually need it. In this case, it doesn't really matter if something like "http:http://" gets stripped off the beginning or "xmlrpc.phphp" gets stripped off the end, so I didn't bother. If it was important to match only a single occurrence, I'd look it up again. Yes, most of the *s can probably be ?s, except in the "(\/)*" bit where * is needed.
