JNI related question

Question

Hi,
I've downloaded some files from the following site;
http://www.geocities.com/Juanga69/parport/
you may be familiar with them, the class basically write/read a byte to/from the parallel port using a c file (i was trying with the comm api but it was giving too much trouble).
My question is this, the class ParallelPort.java is located at C:\parport\ (as is the install instruction).
Now if i have another class, Port.java, which will access the class ParallelPort in another location, lets say, C:\java\, how do i make Port.java see ParallelPort.java ??????
I've tried to add the following to ParallelPort
package parport;
but is it already a package or something because it uses JNI?
Is there a way that you can say,
import c:\parport\ParallelPort or something?

Answer 1

ParallelPort does not belong to a package. c:\parport is only the directory where it is located at. If you have that directory in your CLASSPATH then Java should be able to find it with no problem. If you absolutely must import it, then you can do this:
import ParallelPort;That's it. Another thing that might be happening is if you dont have '.' (dot, current directory) in your class path, Java won't find your Port class. Therefore, you might want to add it to your CLASSPATH like this:
set CLASSPATH=.;c:\parport;%CLASSPATH%notice the '.' at the begining.
