The JAXP API is an optional package for Java 1.1 and above. It is also a standard component of the J2EE 1.3 platform. The full specification and a reference implementation are available from http://java.sun.com/xml/.
SAX and DOM APIs that are actually used for processing XML files
don’t include a standard method for creating a
parser object; this is one of the voids JAXP fills. The API provides
a set of
Factory objects that will create parsers
processors. Additionally, JAXP defines a programmatic interface to
The actual parser and processor implementations used by JAXP are pluggable. You can use the Crimson parser, the Apache Xerces parser (available from http://xml.apache.org), or any other JAXP-compatible parser. Version 1.1 of the reference implementation ships with Sun’s Crimson XML parser and the Xalan XSL engine from the Apache XML project (again, see http://xml.apache.org). Future JAXP implementations will likely replace Crimson with Xerces. There are still variations in support for different levels of functionality across parser implementations. The examples in this chapter have been tested with the Crimson parser that ships with JAXP and all other Sun products.
JAXP 1.1 is included in the J2EE 1.3
platform. To use JAXP with JDK 1.1 or Java2, you can download the
reference implementation from http://java.sun.com/xml/.
