jpython not reading class

[Neil Macneale]

I am new to python,  and very impressed.  I am most interested in using it
to test java classes I have written,  and prototype quickly for java
project for my work.

I have installed jpython,  and it seems to work with all the standard java
classes.  When I try and import a class of my own,  it complains that the
class is not a valid class file:

ImportError: bad java class file in: [edit path]/Timer.class

Now I know that class file works.  I have been using it for months.  Is
the fact that it is part of a package a problem?  I tryed starting from
the package directory and it simply say there were no modules by the name
given.  I am starting jpython from the directory that the class is in, 
and it seems to find the file.  It just doesn't want to open it.

Thanks in advance for any help.
