Struts and Multi-Selects

[TheObserver]

What is the procedure for setting a multi-select in a jsp via a form object from an action?

I am taking data from a multiselect and placing it into a database via getParameters, etc, but I have need to take the data and place it back into a multiselect, somewhat akin to an "edit" capability. As such, I would like to know what the jsp tags for a multiselect are, what format the data needs to be in for the struts multiselect to set the options accordingly, etc.

Unfortunately, I'm not able to find much information on the subject of multi-selects and struts.

Thanks for your time.
