我收到这些消息:

[#| 2010-07-30T11:28:32.723 + 0000 |警告| glassfish3.0.1 | javax.faces | _ThreadID = 37; _TreadName = Thread-1; |将不可序列化的属性值设置为ViewMap :(关键字:MyBackingBean, value class:foo.bar.org.jsf.MyBackingBean)|#]

这些是否意味着我的JSF支持bean应该实现Serializable？还是他们提到了其他一些问题？

我想在Tomcat 7中使用Mojarra 2.1,所以我在我的pom文件中添加了以下依赖项:

<dependency>
       <groupId>com.sun.faces</groupId>
       <artifactId>jsf-api</artifactId>
       <version>2.1.2</version>
     </dependency>

     <dependency>
       <groupId>com.sun.faces</groupId>
       <artifactId>jsf-impl</artifactId>
       <version>2.1.2</version>
     </dependency>

但是,当我尝试启动Tomcat时,我遇到以下异常:
