I am working on a JSP written in JSTL and html-el tags. The JSP is displayed fine.
This JSP has a table. Each row of the table has a
checkbox. Clients may select any number of the
checkboxes and click on a link to invoke a Struts
action.
I would like to pass the checkbox and every column of
each row when the "link" is clicked. What is the
proper way of doing that? My code is shown below(and
also in the attachment:
