Regex to split a URL, not matching

Question

I'm trying to port Steve Levithan's [parseUri JavaScript function|http://blog.stevenlevithan.com/archives/parseuri] to Java, but I'm having problems getting the regular expression to match anything, even basic URLs. I can confirm that the regular expression +^(?:(?![^:@]+:[^:@\/]*@)([^:\/?#.]+):)?(?:\/\/)?((?:(([^:@]*):?([^:@]*))?@)?([^:\/?#]*)(?::(\d*))?)(((\/(?:[^?#](?![^?#\/]*\.[^?#\/.]+(?:[?#]|$)))*\/?)?([^?#\/]*))(?:\?([^#]*))?(?:#(.*))?)+ matches http://www.google.com/, but I can't get it to work in Java. The code I'm using is:
String spec = "http://www.google.com/";
HashMap tempUri = new HashMap();
String[] parts = {"source","protocol","authority","userInfo","user","password","host","port","relative","path","directory","file","query","anchor"};
Pattern pattern = Pattern.compile("^(?:(?![^:@]+:[^:@/]*@)([^:/?#.]+):)?(?://)?((?:(([^:@]*):?([^:@]*))?@)?([^:/?#]*)(?::(\\d*))?)(((/(?:[^?#](?![^?#/]*\\.[^?#/.]+(?:[?#]|$)))*/?)?([^?#/]*))(?:\\?([^#]*))?(?:#(.*))?)");
Matcher matcher = pattern.matcher(spec);
String match;
int i=0;
while(matcher.find()) {
    try {
        match = matcher.group(i);
        tempUri.put(parts, match);
} catch(Exception ex) {
tempUri.put(parts[i],"");
i++;
The problem is, the matcher only ever finds one match (the whole string), it should be splitting it. I'm sure I'm escaping the characters properly.

Answer 1

As usual, after trying for hours in vain, I stumble upon the answer just after posting. :P
Rather than while(matcher.find()), I used if(matcher.find()), then looped through the groups.
For anyone interested, [http://leghumped.com/blog/2008/11/03/java-matching-urls-with-regex-wildcards/|http://leghumped.com/blog/2008/11/03/java-matching-urls-with-regex-wildcards/] might help :)
