What version is the one that came with the JDE?  
(It should print the version when it starts up).

Well, if you start bsh by double clicking the jar file then Java probably 
doesn't have the class path set to include the current directory.

If you could try running bsh from the command line:

  java -classpath bsh-1.0.jar;. bsh.Console

that would include both the jar file and the current directory in the path.

I'm going to try to make bsh friendlier about loading classes not in the class
path in the next release.

Yes, I see.  I just tried it and it does hang.

I'll investigate why.

In general you should be able to use any class in the class path without
explicitly importing it.  e.g.:

  new Foo()
  new mypackage.Foo();

So I think you're stubmling over two problems 1) not having Foo in the
classpath and 2) a bug that you've discovered involving importing explicit
class names.

(sorry ;) )
