multiple select list

I'm having some trouble getting started using a multiple select list widget of the form

    <select multiple size=6 name=resourceLanguageId[]> 

        #foreach ($lang in $languages) 
            <option value="$lang.id"  
            #if ($lang.flag) selected #end
        >$lang.name
        #end

    </select>

I am stuck trying to figure out where to go from here, displaying the items is fine, but I'm not sure how to pass the information about which items are selected to my java code.  Can anyone point me the right direction?

Thank you,

Not a velocity question, but assuming you are POSTing to a servlet, then 
you have an HttpServletRequest - lets call it req.

do the following:

     String[] langIds = req.getParameterValues("resourceLanguageId[]");

the selected ids are in the array. Easy!

HTH,

Martin

not really a velocity question...

If you are using a framework like Struts or Turbine, you should rather post your question to the corresponding list.
