Hi. 

If you are writing an application, you need to make 
sure that the jar file is in your application's 
CLASSPATH. Append the full path to the jar file, 
including the jar file name itself to 
your CLASSPATH environment variable. (The CLASSPATH
is a list of directories and jar files under which
a JVM will by default search for classes. Like the
PATH variable, entries are separated from one another
with a ':'" on UNIX platforms, ';' on Windows.)

If you are writing an Applet, you need to add an
archive attribute to the applet tag in your html,
whose value is a path from your html file to the
jar file. e.g.

<APPLET 
    code="mypkg.MyApplet" 
    codebase="classes" 
    archive="jars/jdbc6.5-1.2.jar"
    width="150"
    height="150"
>
</APPLET>

    good luck,
      Steve
