Appendix C — The PATH Environmental Variable

On most computer systems (including Windows) the PATH environmental variable must be set up correctly in order for you to use the Java compiler and the Java virtual machine easily. The Sun documentation on this subject is here:

• http://java.sun.com/docs/books/tutorial/essential/environment/paths.html
• http://www.java.com/en/download/help/path.xml

This appendix deals only with Windows operating systems. For other OSs, see the Sun documentation in the above list (or search the Web).
