How To Pass a Parameter to JSF Application Using URL String

if you have the following URL:

http://your_server/your_app/product.jsf?id=777

, you access the passing parameter id with the following lines of java code:

FacesContext fc = FacesContext.getCurrentInstance();
String id = (String) fc.getExternalContext().getRequestParameterMap().get("id");

From the page, you can access the same parameter using the predefined variable with name param. For example,

<h:outputText value="#{param['id']}" ></h:outputText>
