one action from shared with multiple jsp pages

[yanming lu]

How does struts pass a selected item from one jsp page to another?

Here is what we'd like to do:

there is one form including 2 fields: name of text field and department of 
selection field (could be multiple selection).

there are two pages which share this form. page 1 to select number of 
department, second page to enter name.
How do we pass the selected department(s) to the second page and when the 
name is entered, we could save both data?

Thanks,

how to add data into a form?

[yanming lu]

Here is what i'd like to do:

page 1 has form with ID and NAME. The NAME field is hidden so it is blank. 
This form is configured as a java bean and set in the struts-config.xml 
file.

when user click the 'save' button, the id of the form is carried to next 
page, page 2. But in the between, I look at the dababase and find the name 
base on this id and call the setNAME() function to set the name value in the 
same form. But this NAME does not appear on the second form. Why?
