Bansi,
Usually, you would just add a new FacesMessage to the FacesContext like so:
facesContext.addMessage(null,
new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Duplicate id found", "detailed
description...."));
(I'm assuming that your FacesUtils class has a addErrorMessage() method
which you could use instead.)
And then display it in your error page like so:
<h:messages globalOnly="true"/>
What does ex.getMessages() return?
