struts 1 : retrieve, populate and hide data from a select tag

[samantha clarkson]

Hello Everybody,

i have a list List<RoleBean> lRolesAttribues; which is setted into the request using line below in the action :

request.setAttribute("listeRolesAttribues", lAttributionRolesForm.getRoot().getInitData().getlRolesAttribues());

the object RoleBean is a javabean containing attributs, and those setters/getters

private String lId;
private String lLibelle;
private String lDescription;

                                            <select multiple="multiple" size="5" name="stations_sel" id="stations_sel" style="width: 350px;">
                                                <logic:iterate id="mykey" name="listeRolesAttribues" >
			                                    	<option><bean:write name="myKey" property="lLibelle" /></option>
			                                    </logic:iterate>					
                                            </select>

my first question is how can i retrieve the list of Roles selected, Or better how can i retrieve the Ids of roles selected without using the list of (String lLibelle) and searching for the corresponding id?

I really appreciate your help.
