javascript以及java中的正则表达式验证

regex.jsp:

 <script>
	var pattern = "http://www.sina.com/jacky"
	var regex = /http:\/\/(w{3})\.(\w+)\.(\w+)\/(\w+)/g;
	/*
	* g--全局匹配模式 i--不区分大小写
	*/
	var a = pattern.match(regex);
	document.write(a);
  </script>

?regex.java:

String buffer = "to_be_tested"
Pattern p = null;
Matcher m = null;
p = Pattern.compile("[atcgnATCGN]+");
m = p.matcher(buffer);
boolean b = m.matches();
