Burada Eclipse, JSF 2.3 ve Tomcat 9 kullanarak bir web projesi yaratıyoruz ve çalıştırıyoruz.
Öncelikle JSF 2.3 için gereken bağımlıklar eklenmelidir. JSF 2.3 artık CDI gerekmesinden dolayı CDI apisi ve onun implemantasyonu olan Weld eklenmelidir :
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>javax.faces</groupId>
<artifactId>javax.faces-api</artifactId>
<version>2.3</version>
</dependency>
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>
<version>2.3.9</version>
</dependency>
<dependency>
<groupId>javax.enterprise</groupId>
<artifactId>cdi-api</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>org.jboss.weld.servlet</groupId>
<artifactId>weld-servlet</artifactId>
<version>2.4.8.Final</version>
</dependency>
Ardından CDI için WEB-INF için beans.xml eklenir :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_2_0.xsd"
bean-discovery-mode="all" version="2.0">
</beans>
Ardından Tomcat 9 için META-INF altında context.xml eklenir :
<Context>
<Resource name="BeanManager"
auth="Container"
type="javax.enterprise.inject.spi.BeanManager"
factory="org.jboss.weld.resources.ManagerObjectFactory"/>
</Context>
web.xml'e aşağıdaki eklenir :
<listener>
<listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
</listener>
<resource-env-ref>
<resource-env-ref-name>BeanManager</resource-env-ref-name>
<resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
</resource-env-ref>
web.xml'in son hali şu şekilde olmalı :
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" id="WebApp_ID" version="4.0">
<display-name>JSF2_3Test</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.xhtml</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<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>*.xhtml</url-pattern>
</servlet-mapping>
<listener>
<listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
</listener>
<resource-env-ref>
<resource-env-ref-name>BeanManager</resource-env-ref-name>
<resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
</resource-env-ref>
</web-app>
Artık ortam hazır demektir. En basit olarak aşağıdaki gibi bir index.xhtml sayfası yapalım :
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<head>
<meta charset="ISO-8859-9"/>
<title>Merhaba JSF 2.3</title>
</head>
<body>
<h:outputText value="Merhaba JSF 2.3"></h:outputText>
</body>
</html>
Artık bu projeyi Tomcat 9'da çalıştırabiliriz. Bu projeyi çalıştırdığınızda aşağıdaki gibi hatalar alabilirsiniz :

Bu durumda aşağıdaki gibi bir bean eklemek gerekir :
package com.fibiler.jsf2_3.hello;
import javax.faces.annotation.FacesConfig;
import javax.faces.annotation.FacesConfig.Version;
@FacesConfig(version = Version.JSF_2_3)
public class ConfigurationBean {
}
Bunu eklendikten sonra tomcat 9'u çalıştırırsanız hata gelmeyecektir. Hatanız sebebi projenizde bir bean olmamasıdır. Yukarıdaki ConfigurationBean'i eklemek yerine aşağıdaki gibi bir bean yapıp onu kullanalım:
import javax.inject.Named;
@Named
public class HelloBean {
private String message="Merhaba JSF 2.3";
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
Sayfa şu şekilde olacak :
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<head>
<meta charset="ISO-8859-9"/>
<title>Merhaba JSF 2.3</title>
</head>
<body>
<h:outputText value="#{helloBean.message}"></h:outputText>
</body>
</html>
Artık proje hata vermeyecektir.
