By: Grenfel in JSF Tutorials on 2007-09-18
To install JSF, you need to follow these steps:
-
Download the JSF library: You can download the latest version of JSF from the official Oracle website or from a third-party website.
-
Add the JSF library to your project: You can add the JSF library to your project by copying the downloaded jar file to the "lib" directory of your project.
-
Configure your web.xml file: You need to configure the "Faces Servlet" in your web.xml file. Here is an example:
<servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping>
- Create a JSF page: You can create a JSF page using HTML tags and JSF tags. Here is an example:
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"> <head> <title>JSF Example</title> </head> <body> <h:form> <h:inputText value="#{helloBean.name}" /> <h:commandButton value="Say Hello" action="#{helloBean.sayHello}" /> <h:outputText value="#{helloBean.message}" /> </h:form> </body> </html>
- Create a Managed Bean: You can create a Managed Bean using the "@ManagedBean" annotation. Here is an example:
@ManagedBean public class HelloBean { private String name; private String message; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } public String sayHello() { message = "Hello, " + name + "!"; return "success"; } }
These are the basic steps to install JSF and create a simple JSF application.
