How can i get checkbox values from struts2 checkbox in displaytag to action class

Question

I am working on struts2 application in which i am using displaytag for pagination support.

Now i want a check box for each row in t

Answer 1

This is how I would do it.

1. instead of 'id' for all id columns, append a sequence number so that each id has a unique name, such as 'id1', 'id2' etc

2. create a interceptor that collects values of parameters prefixed with 'id'

3. configure your action to use the interceptor

My strut fu is rusty though. There probably is a better way.

Answer 2

If you add a String[] to your action named the same as your checkbox(s) and expose it via accessors (getters/setters) struts 2 should auto populate it.
