Using the JSP model for using a bean to store form data (i.e. use <jsp:setProperty> to 
store form input fields - use <jsp:getProperty> to retrieve data) - How does 
Java/server keep track of the beans from JSP to JSP page?

For example - I use 3 JSP pages to process one form - first JSP page accept input - 
second JSP validate input (if invalid back to first page) - third JSP update database.

If 5 users are inputting data into the form - how are the beans tracked?
Serialization?

Does scope=�session� do this automatically?  With more than 1 user?  How do I 
release/reset the bean if I only need the bean for a few jsp pages - but user does 
more during the session?

Is this the best way to validate (i.e. using beans)?  Is there a better/easier way?
