How to disable OK button of faces message and make it modal

Question

Hello all,
I am using this code for displaying faces messages programatically :
*public String showMessage() {*
String messageText=”A prgramatic af:message”;
FacesMessage fm = new FacesMessage(messageText);
** set the type of the message.*
** Valid types: error, fatal,info,warning*
fm.setSeverity(FacesMessage.SEVERITY_INFO);
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, fm);
return null;
But the problem here is it is showing an OK button at the bottom but I want to disable that button. How can I disable that button? For closing the message we are using function keys like ' F8 ' and we are using javascript for that.
Also we can not use dialog there because we are adding the messages programatically and showing the faces message programatically.
Also I want this message to have modal behavior so that until user press F8 for closing that message, user would not be able to navigate to the main form.
How can I achieve this?
Please Suggest.
Thanks
