Java EE (Java Enterprise Edition) General Discussion

Fairly new to JSTL so please excuse my ignorance. I am creating a button(link) that will expand to show rows of data when clicked or collapse when clicked again. I already have a bean populated from the backend that contains a collection of my data. Want to know the best way to access and display the data using Struts tags or JSTL? Have performed similar code using scriplets but my form or collection is not in 'session' and would like to keep it that way.
