Example Application

Let us create a test JSF application to test the above tag.

Step	Description
1	Create a project with a name helloworld under a package com.tutorialspoint.test as explained in the JSF - First Application chapter.
2	Modify home.xhtml as explained below. Keep rest of the files unchanged.
3	Compile and run the application to make sure business logic is working as per the requirements.
4	Finally, build the application in the form of war file and deploy it in Apache Tomcat Webserver.
5	Launch your web application using appropriate URL as explained below in the last step.

home.xhtml

   <head>
      <title>JSF Tutorial!</title>
      <h:head>
         
         <script type = "text/javascript">
            function showCheckedValue() { 
               alert(document.getElementById('jsfForm1:chkRememberMe').checked);	 
            }
         </script>
      </h:head>
   </head>
   
   <body>
      <h2>h:selectBooleanCheckbox example</h2>
      <hr />
      
      <h:form id = "jsfForm1">
         <h3>Get value from selectBooleanCheckbox field</h3>
         <h:selectBooleanCheckbox value = "Remember Me" id = "chkRememberMe" />
         <h:commandButton value = "Show Checked" onclick = "showCheckedValue()" />
      </h:form> 
   
   </body>
</html>

Once you are ready with all the changes done, let us compile and run the application as we did in JSF - First Application chapter. If everything is fine with your application, this will produce the following result.
