Package problems in Linux

Question

I'm working on a large program and when all files are located in the same directory, everything works well. To organize things, I want to use packages and package statement, declared the files public and stored them in what should be the appropriate directories. I have the following.
package visortool.interaction;
import ...;
public class DisplayWindow extends JFrame
and a second class
package visortool.fraf;
import visortool.interaction
public class FrafViewer
My classpath is
/home/simon/school/java/visortool/
Any Linux/Java expert that could helpe me?
regards
simon

Answer 1

From there, I ran "java visortool/VisorTool" and it
worked, but why can I not execute the program from the
directory containing the VisorTool.class file?Because you're including "." (current directory) in your classpath, which in this case is not valid, since that directory does not contain classes in the "root" package (no package statement). Including the "current" directory (or any directory for that matter) is only valid when that directory has classes in it which correctly follow the package hierarchy.
