Really silly question folks, sorry about this.
How do I include a jar file in my classpath?
I'm using a PC running Windows 98 (second edition).

SET CLASSPATH=C:\ADIRECTORY\ajarfile.jar;%CLASSPATH%
You would probably need to do that in your C:\AUTOEXEC.BAT file and then reboot the machine.
The %CLASSPATH% tells the system to put the "old" or "previous" value of the CLASSPATH at the end of the new CLASSPATH. If there was no previous CLASSPATH you can use SET CLASSPATH=C:\ADIRECTORY\ajarfile.jar;.
Note the semicolon and period at the end!

Hi Steve,
You can just drop a copy of the jar in your jre/lib/ext directory or you can append the fully qualified name to your CLASSPATH envrionment variable (eg C:\MyJars\MyClasses.jar) or you can build a classpath on most of the java utilities (like javac, java, etc.) with a -classpath flag like this:
javac -classpath .;C:\MyJars\MyClasses.jar source.java
Hope this helps,
Michael Morris
