You can easily protect files so that only authorized clients can
download them, but if you want your code to be executed by the
client's JVM it also means that he have to be able to download the
code. In other words, there is no way to allow downloading and do not
allow it. OTOH you probably can arrange your system in such a way that
some important parts are executed by server and thus you do not need
to supply the code for this part.
