populating a Form from a DB?

[Richard Yumul <rm...@polexis.com>]

What's the process to dynamically populate a form?  For example, say I click
on a link w/ a URL something like:

user.jsp?userid=34

How would I code the user.jsp (and/or the accompanying classes) to fill in
the form in user.jsp with user# 34's data in a struts-centric way?

(If there's documentation somewhere on how to do this, please let me know,
thanks)

Thanks,
Rich

The Struts example application does exactly this sort of trick.

On the registration.jsp page, do a View Source and look at the links in
the table of subscriptions down at the bottom -- specifically the edit
links.  You will see that they link back to an action
(/editSubscription.do) rather than directly to a page.  Which subscription
is being referenced is passed as query parameters.

The /editSubscription action looks up the existing subscription,
prepopulates the ActionForm bean, and forwards to the subscription.jsp
page for display.  When you submit the updated subscription, it goes to a
different action (/saveSubscription) to be stored in the database.

I normally do something like:
  user.do?action=getInfo&userid=34

Then based on the action, you can populate the bean
with the info you want and forward it the jsp page.
