How to use multiple attribute on html:select struts tag

I hope someone can help with this problem.

I have a select box that has a list of items contained in it and the user can select multiple values.

The property 'software' is a java.lang.String[] property from a form bean and the 'SoftwareList' property is an ArrayList. I can display the list no problem and the user can select one or more options and I can grab the selections and save to the database.

The problem arises when I re-display the page and I want to select all the items in the select list that have been retrieved from the database. I set the property 'software' as a String[], and I have validated the array right up to when the page is called. I can't get it to select all items that were previously chosen, infact none of the items are selected.

What am I doing wrong?

Thanks,
Gordon
