A class that is not on the classpath cannot call a native method.
Since the servlets dir is not in the classpath (on Jrun anyway), you
can't do this.
Jrun has a custom classloader that reloads classes if modified without
having to restart the jvm - this will break if the servlets dir is in
the classpath.
So...
The solution is to create an interface class that loads the native code,
and put IT in the classpath. Then your servlet can create an instance
of it, and use it to call native methods.
Note - that the .dll also needs to be on your classpath.
2nd Note - the system classpath and the servlet engines classpath may
not neccesarily be the same.
