Also note how other tools, such as the Java<FONT SIZE="-2"><SUP>TM</SUP></FONT> Servlet Web Development Kit and the MySQL database driver can be included in the <code>CLASSPATH</code>. These may or may not apply to your needs.<P>Enter the following to set a <code>CLASSPATH</code>:<P><pre>SET PATH=%PATH%;%JAVAHOME%\BINPATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\JDK\BIN;SET CLASSPATH=.;C:\jdk\lib\tools.jar;C:\jswdk\lib\servlet.jar;C:\mm.mysql.jdbc-1.2b;%CLASSPATH%</pre><P><B>Note:</B> To ensure programs locate the complier and APIs, keep the <CODE>SET CLASSPATH</code> command on one line. <P>Save the file and close the editor.
