What is the relationship between the Sun Projet X library and JAXP? Is there any other library aside from Project X which allows regestering my own classes which are created when certain XML elements are encountered (like factory.addMapping (props, classloader) in Project X)?
Shane Curcuru Project X was a parser originally available from Sun that has now been donated to the Apache Software Foundation. See http://xml.apache.org/crimson/ for more information on Crimson. Current (Nov-2001) releases of Crimson are used as the reference implementation of the javax.xml.parsers package that forms half of the JAXP 1.1 specification. Xerces is another popular Apache parser that also implements the parsing half of JAXP 1.1.
