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:commandLink example</h2> <hr /> <h:form> <h:commandLink value = "Page 1" action = "page1" /> </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.
