I have several a java servlet and several java classes.  Based upon an input
file, the servlet passes arguments and the user's session to the classes
which return data back to the servlet.

I have many concerns about this model when taking it to a many user
environment.  One of the biggest of these concerns is that occassionally a
class will fail to return data back to the servlet.  Upon a reload of the
page, the classes work fine.

Often the error messages I get involve variables not being set in a user's
session, however I think this is because the class that should of set that
variable didn't execute properly.

Is there anything I might check specifically?  I use Class.forName("class
name").newInstance() to access the class and run its methods.

Thanks for any help,
