How to Bookmark URL in JSF using GET method and ViewParam – Example

By default, JSF makes POST request to the server. The HTTP method POST is useful for INSERT and UPDATE operation. For example, GMAIL signup form. When a user fills and submits the form. A new user will get inserted into the database.

The HTTP method GET is useful for SELECT operation, which retrieves a data from the server and displays it in the UI. For example, GOOGLE search result, Search something in google, Copy the URL and paste it in the different tab, you will get the same result. The URL can be bookmarkable. Here below is a GET URL look like

In the above URL, The right side of the ? symbol is Query parameters. It contains one or more name=value pairs; ‘s’ is the name and ‘jsf‘ is value here.

In this section, we walk through on the following topics

1. Create a Bookmark URL in JSF  using <h:link> tag and outcome attribute

2. Pass the Query Parameter values to a Java bean class using JSF <f:ViewParam>


Create a bookmarkable URL in JSF – Example


In this example project, I have created two JSF pages. Index.xhtml has list of GET URL’s contains employee ID and name as query parameters; On clicking the URL will go to employee.xhtml page displays employee ID and name from the QUERY parameters


Below is the index.xhtml page. This contains a list of GET URL. Those URL;s contains two query parameters; ID and name. We can generate this URL’s dynamically through Java List, MAP or some another ways. 


  1. The first & second <h:link>tag uses outcome attribute. The outcome refers the view ID. The <h:link>renders like below when the pge loads 
    1. <a href=”employee.xhtml?id=1&amp;name=govind”>Govind</a>..
  2. Use the &amp; to separate query parameters 
  3. We can also use <f:param> to pass the query parameters 



Below is the employee.xhtml page; This page display the employeeID and employeeName from the managed bean class. 

  1. The employee page looks like http://localhost../../employee.xhtml?id=1&name=govind
  2. At first, the  <f:viewParam> tag fetch the ID from the URL (Query parameter) and pass it to the managed bean method User.setEmployeeid() & The second <f:viewParam> tag fetch the NAME(Query Parameter) from the URL and pass it to the managed bean method User.setEmployeename()
  3. The <f:viewAction> tag calls the User.onload() method during postBack lifrcycle 

Also notice, I used xmlns:f=”” instead of xmlns:f=”” . 



Below is the Managed Bean java class. 



This is how the Page looks like in the browser
