I have a problem which I have a kludgy solution for, and have to believe
there is a more elegant way of doing it... Here's the scenario.
The page displays a non-editable list of records in a database, with a
checkbox at the beginning of each row. The list is indeterminate length,
A couple of options:
1) Use a key for the checkbox that is a combination of the two keys,
combined with a character that cannot be in the keys themselves (e.g.
key1::key2). They just separate them in the action, or better yet, have the
form separate them.
2) Use JavasSript on the check of a row
Is it mandatory to create ActionForm class for each JSP if we want to

Does it not make the ActionForm class dependent on the UI and liable to

Is there a way of dynamically creating the ActionForm class
No, you can use
(String) request.getHeader(referer);
To get the refering URL, but personal firewalls and even browser settings
allow it to be turned off, so you will always need to have a backup
mechanism for loading from the referer in the case where it's null.
