XML Enhancements for Java

Operating systems: Windows, Linux, or UNIX. On Windows, use the xjc.exe/xj.exe executable files from a Cygwin shell or a Windows command prompt. On Linux/UNIX, use the xjc/xj scripts. The -h/--help option lists the available command line arguments.

Software: Java Run-time Environment (JRE) 1.4 (for the compiler and run-time system). XJ relies on the standard JAXP XML parser and the Xalan XSLT engine provided by JRE 1.4.

XJ consists of two zip files:

• xj-bin-1.0.zip: The XJ compiler and run-time system. This archive is sufficient for compiling and executing XJ programs.
• xj-src-1.0.zip: Source for modified portions of the Eclipse JDT, on which the XJ compiler is built. Downloading this archive is optional; this archive is not required for the compilation and execution of XJ programs.

Extract the xj-bin-1.0.zip file, which will create the XJJDT directory. The compiler and run-time executable files (xjc and xj), located in the bin sub-directory of XJJDT, use the following mechanisms to locate the JRE (Java Runtime Environment) installation:

• First, if the JAVA environment variable is set, it is assumed that it specifies the full path to the java executable.
• Otherwise, if the JAVA_HOME environment variable is set, it is assumed that the bin sub-directory of JAVA_HOME contains the java executable.
• Finally, the PATH environment variable is used to find the java executable.

The XJJDT directory is structured as follows:

• Compilation:
  • bin/xjc.exe (Windows/Cygwin)
  • bin/xjc (UNIX/Cygwin)
• Run:
  • bin/xj.exe (Windows/Cygwin)
  • bin/xj (UNIX/Cygwin)
