    One very important rule when dealing with any programming language is to not
    call it a liar until you are 100% sure that it is, in fact, lying.

    My previous experience teaching university students to use Java and various
    other languages leads me to suggest that, the compiler is not lying and that
    you have an error of some type (perhaps a misunderstanding of the use of
    third party packages). The compiler is telling you that the package that
    you are referring to does not exist.

    Check your system CLASSPATH for typos (be vigilant !). If you are confident
    that the jar (or whatever it is) is in the CLASSPATH, check manually, by
    opening the jar or directory structure to ensure that the package does
    actually exist. I have also had problems in the past where the JAR file
    opened successfully with some independant application such as Winzip, but
    failed when the command-line jar was used - check for validity of the jar
    (if this is how it is distributed).

    Failing all, erase your system CLASSPATH (they are evil anyway), and
    manually set it at compile time with the -classpath switch, who knows, you
    might discover a typo that you missed.

    I use Apache Ant for such things as compiling, etc. If I specify a jar file
    to be used for the -classpath switch and it doesn't exist, I know this
    immediately when I invoke ant in verbose mode (-v), because it points it
    out. This technique of using a third party application (and not human eyes)
    will help to ensure that you have no typos.

    Good luck.
