Hi all,
    I bought JBuilder and tried to port some of my own prewritten code
and some third party classes into a project.  I have my directory setup
correctly (I think, they compile and run under jdk1.1 and appletviewer),
but when ever I try to compile I get the errors:

cannot access class Msql; class file:  Msql contains wrong class:
msql.Msql
cannot access class MsqlException; class file:  MsqlException contains
wrong class: msql.MsqlException

msql is a directory under my project file, I import it with
             import msql.*;

It all works nicely with the JDK, whats wrong with Jbuilder? I already
tried the classpath and all the different combinations of Caps
