jsf

JSF是一个规范，并没有做实现，目前比较流行或者主要的实现有MyFaces、IceFaces和RichFaces。本人刚刚入门，对这些实现具体细节的差别没有搞明白，但我想应该都差不多的。
项目中，使用了RichFaces，所以就如何使用RichFaces做说明。
搭建开发环境：
1、在MyEclipse中建立web工程。
引入jar包
richfaces-api-3.2.0.GA.jar
richfaces-impl-3.2.0.GA.jar
richfaces-ui-3.2.0.GA.jar
commons-logging.jar
commons-digester.jar
commons-collections.jar
commons-collections-3.2.jar
2、配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>a4jEchoText</display-name>


<context-param>
<param-name>org.richfaces.SKIN</param-name>
<param-value>blueSky</param-value>
</context-param>
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>

<filter>
<display-name>RichFaces Filter</display-name>
<filter-name>richfaces</filter-name>
<filter-class>org.ajax4jsf.Filter</filter-class>
</filter>


<filter-mapping>
<filter-name>richfaces</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>




<listener>
<listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>



<!-- Faces Servlet -->
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<!-- Faces Servlet Mapping -->
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<login-config>
<auth-method>BASIC</auth-method>
</login-config>
</web-app>
3、配置faces-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
"http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config>
<managed-bean>
<managed-bean-name>bean</managed-bean-name>
<managed-bean-class>demo.Bean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>text</property-name>
<value/>
</managed-property>
</managed-bean>
</faces-config>
4、写back bean
public class Bean
{
private String text = "aaaaaaaa";


public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
5、写jsp页面
<f:view>
<h:form id="testForm">
<rich:panel header="Simple Echo">
<h:inputText size="50" value="#{bean.text}" >
<a4j:support event="onkeyup" reRender="rep" limitToList="true" data="#{bean.text}" oncomplete="alert(data)"/>
</h:inputText>
<h:outputText value="#{bean.text}" id="rep" />
</rich:panel>
</h:form>
</f:view>

访问时，首先将此发布到tomcat下，访问：http://localhost:8080/Richfaces/test.jsf即可。
这样一个完整的jsf demo就算完成了。
