Question: How to pass a parameter to the JSF application using the URL string?Answer: 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']}" /> Note: You have to call the jsf page directly and using the servlet mapping. |
