Having a minor problem which hopefully someone can advise me on. I have a
'service' class that calls the 'printAddPage' of this class
(AddComponentManager). This generates a HTML form, which (when the user
submits) in turn calls the 'doPost' method of this page. Unfortunately,
when the doPost method is called, the server (Java Web Server1.1.1) returns
a 404 file not found. Any ideas why this is falling over (comments about
how I'm going about this would also be welcomed).
Cheers,
Pete
