JAXP
Starting with Java 1.4, Sun bundled the Crimson XML parser and the SAX2, DOM2, and TrAX APIs into the standard Java class library. (TrAX is an XSLT API that sits on top of XML APIs like SAX and DOM. We'll get to it in Chapter 17.) Sun also threw in a couple of factory classes, and called the whole thing the Java API for XML Processing (JAXP).
Crimson is a reasonably fast parser and worth your consideration. The fact that this implementation is bundled with Sun's virtual machine is a major plus. It allows you to distribute Java programs that use XML without having to add several megabytes of your own parser and interface classes. However, API-wise there isn't a whole lot new here. As I said before, when starting a new program you ask yourself ...
