Your examples and situations are OK to get the import instruction
running ... but this is not my problem.

I have several pakages and the root  directory for them is on my
CLASSPATH .. the javac can find  them and import anyone (inside Forte
or on command line - equaly)

My problem  is to run  or DEBUG from Forte .. because it is looking for
my class  on my source directory (that is far diferent from my package
tree) and then I have "java.lang.NoClassDefFoundError:
Banrisul/BanrisulGUI
Exception in thread "main"" error.
(same error as I have called java command line with an inexistent
class)

I added my path to CLASSPATH on Debugger Execution and External
Execution options but no difference ...

Any thought?
