seam (jsf) messages question

[xinhua]

hi,
is that possible to get facesMessages ojbect WHEN a page is rendered?

i created a backing bean MsgBean and bind it with h:messages

 <h:messages id="mms" globalOnly="true" layout="list"
 styleClass="errors" binding="#{msgbb.msgs}"/>

public class MsgBean {

 UIMessages msgs ;

 public UIMessages getMsgs() {
 return msgs;
 }

 public void setMsgs(UIMessages msgs) {
 this.msgs = msgs;
 }

but i donnot know how to get message content through getter and setter. :.....( or there is a seam way to do that?

can anyone help?
