Thanks.  I unziped and add the directory in the directory.  However, it 
still didn't work.  I even tried to put the directory in the same folder 
as in my test file so that I can use the package.  It turned out I still 
got the message: cannot access Jama.Matrix.  If the Jama directory is 
not in my folder, the error message would become : package Jama does not 
exist.

    You need to unzip the zip file and add the directory above the
    resulting
    "Jama" directory to your classpath instead (assuming that zip file
    contains the same stuff as the version I got a few years ago).

    Most open source Java products these days will provide .jar files,
    which
    you would explicitly add to your classpath (rather than the directory
    containing the class files).  But Jama was released long before this
    became common practice.

    A side note - if you're running from the command-line and adding these
    things to your "global" classpath (changing the environment variable via
    Windows dialogs), then you may run into problems if you're working on
    more than one project.  This is because any time you run any Java
    program, Jama (and whatever else you put in the classpath) will be on
    your classpath whether you want it there or not.  How to properly deal
    with that is really beyond the scope of this mailing list and will be
    heavily dependent on your environment, what tools you use, etc.  Just
    thought I would point it out.  I suggest finding a colleague with more
    extensive Java knowledge.
