JavaBean vs Post from a JSP

Hello ranchers,
I need information about populating a bean in a JSP page just before submit the request to a servlet. There's a way to do it? or I must read all the params in the servlet and update the bean, before processing it?
Here is the big picture:
1- useBean to populate my FORM
2- Modify the data
3- set the new bean property to send to the servlet
4- processing
5- forward somewhere else the updated bean
thanks

Not possible.
All of the Java in your JSP page executes before the HTML page is sent to the client. Once sent, your JSP is done with its job; no further Java processing is possible.
The only thing you can do once the page has been sent to the client is the usual DHTML/Javascript processing.
