Is HawTags a re-implementation of HAWHAW?
No, HawTags is based on the original HAWHAW PHP software. It is not a Java port of HAWHAW. HawTags is build upon Quercus, a pure Java-based PHP implementation from Caucho Technology. The HawTags Java code is a wrapper on top of the hawxy.php software. The HawTags tag library creates a temporary HAWHAW XML document from a JSP page and transforms it to appropriate markup output by means of hawxy.php and hawhaw.inc. HawTags users can benefit from the newest HAWHAW PHP code, by simply adding new releases of the HAWHAW PHP code to their .war files.
