JavaServer Faces 2.0 can not be installed解决方案

http://www.cnblogs.com/jebeljebel/p/4421098.html

问题描述：maven项目出现如下错误

JavaServer Faces 2.0 requires Dynamic Web Module 2.5 or newer..Maven Java EE Configuration     Problem
JavaServer Faces 2.0 can not be installed : One or more constraints have not been satisfied..line 1 Maven Java EE Configuration Problem

 

解决方案：

首先，将webapp下的web.xml文件

1  <?xml version="1.0" encoding="UTF-8"?>2   <!-- <!DOCTYPE web-app3  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"4  "http://java.sun.com/dtd/web-app_2_3.dtd">

 

替换为

1 <web-app xmlns="http://java.sun.com/xml/ns/javaee"2     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"3     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 4                         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"5                         version="3.0">6     <display-name>Archetype Created Web Application</display-name>7 </web-app>

 

然后，关闭Eclipse，改项目下的.settings\org.eclipse.wst.common.project.facet.core.xml，将 版本改成为3.0,将成后是<installed facet="jst.web" version="3.0"/>，再启动Eclipse.

最后，在Problems View的出错提示右键选Quick Fix，再按提示确定就OK；或者,右键项目->Maven->Update Project

=====================

此时，问题一般解决。如还不能解决，尝试在pom.xml中加入如下代码：

 

 1     <build> 2         <finalName>chm</finalName> 3         <plugins> 4             <plugin> 5                 <artifactId>maven-compiler-plugin</artifactId> 6                 <version>2.0.2</version> 7                 <configuration> 8                     <source>1.6</source> 9                     <target>1.6</target>10                 </configuration>11             </plugin>12         </plugins>13     </build>
