Examples: Java Server Faces

Hello Boss

My First JSF application, contains a home page, then you have to type a Emmanuel as user : helloBoss2-jsf.zip
Once installed on your localhost (port 8080), you can access it using this link: localhost:8080/helloboss2.0/
The interesting files are:

src/helloworld/helloBean.java The bean responsible for the verification of usename (and no password yet).
web/hello.xhtml: contains the definition of the form and its links to the managed beans
web/response.xhtml: This content is displayed once the user has been successfully logged in the system.

MyFaces and Tomahawk

This example can be downloaded in one big zip file: myFacesExample2.0.zip.
Once installed and deployed on your localhost, it should be accessible under the following URL localhost:8080/myFaces2.0/ The following files are interesting:
