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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns = "http://www.w3.org/1999/xhtml">
   <head>
      <title>JSF Tutorial!</title>
   </head>
   
   <body>
      <h2>h:graphicImage example</h2>
      <hr />
      
      <h:form>      
         <h3>Image</h3>
         <h:graphicImage value = "/images/jsf-mini-logo.png"/>
      </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.
