I am trying to use Listbox with multiple selections

<s:decorate id="teamFitReasonDecoration" template="layout/edit.xhtml">
 <ui:define name="label">Team Fit Reason</ui:define>
 <h:selectManyListbox id="teamFitReason" value="#{interviewHome.instance.teamFitReason}">
 <f:selectItems value="#{form.options}"/>
 <a:support event="onblur" reRender="teamFitReasonDecoration" ajaxSingle="true"/>
 </h:selectManyListbox>
 </s:decorate>

my Backend Bean looks like

 private List<SelectItem> options;

 public FormBean()
 {
 options = new ArrayList<SelectItem>();
 SelectItem option = new SelectItem("ch1");
 options.add(option);
 option = new SelectItem("ch2");
 options.add(option);
 option = new SelectItem("ch3");
 options.add(option);
 option = new SelectItem("ch4");
 options.add(option);
 option = new SelectItem("ch5");
 options.add(option);
 }

public List<SelectItem> getOptions()
 {
 return options;
 }

how to I place selected options teamFitReason into a database.
ie List of values into a database column which is a String
