To use Xalan-Java, you need the following:

• The JDK or JRE 1.3.x, 1.4.x, or 5.x

You can get the JDK or JRE from IBM developerWorks or java.sun.com.

• xml-apis.jar (JAXP APIs)
• xercesImpl.jar (or another XML Parser)
• xalan.jar or xsltc.jar
• serializer.jar
• (Optional) Xalan Java source code
• (Optional) Packages to support extension functions and elements

There are 2 binary distributions available; you only need to choose one of them. Both binary distributions contain xml-apis.jar and xercesImpl.jar from Xerces-Java 2.7.1.

• The first binary distribution, xalan-j_2_7_0-bin.zip or xalan-j_2_7_0-bin.tar.gz, contains the Xalan Interpretive processor, the Xalan Compiled processor (XSLTC) and the runtime support packages in a single jar, called xalan.jar.



• The second binary distribution, xalan-j_2_7_0-bin-2jars.zip or xalan-j_2_7_0-bin-2jars.tar.gz contains the Xalan Interpretive processor in xalan.jar, and the Xalan Compiled processor (XSLTC) and the runtime support packages in xsltc.jar.

The binary distributions can be downloaded from the xalan-j distribution directory.

There is an optional source distribution available for doing your own Xalan-Java builds; see Build notes. You can download the source distribution from the xalan-j distribution directory.

If you plan to run XSLT extensions implemented in languages other than Java, then you will need an implementation of the Bean Scripting Framework (BSF). An open source implementation is available for download from Apache. See the Apache Jakarta BSF project. If you plan to run XSLT extensions implemented in scripting languages, you will need bsf.jar and one or more additional files as indicated in extensions language requirements.

To access previous releases, see the xalan-j archive directory.

The Xalan-Java download includes xercesImpl.jar from Xerces-Java 2.7.1. In conjunction with xml-apis.jar, this is all you need to run Xalan-Java with the Xerces-Java XML parser. You can, however, download the complete Xerces-Java binary or source distribution from the xerces-j distribution directory. If you cannot find Xerces-Java 2.7.1 at that location, have a look at the Apache archive location for Xerces Java.

If you plan to use a different XML parser, see Plugging in a Transformer and XML parser.
