Answer 1

看起来你在类路径中的某个地方有一个旧版本的Servlet API，它覆盖了Tomcat 6.0 Servlet API（Servlet API 2.5）。

Answer 2

这是奇怪的错误。问题原因： - Java-Built路径中的servlet api会覆盖你的Tomcat Server的servlet-api。解决方案：-first转到你的项目建立路径并删除你的版本的Sevlet-api 你的Tomcat Server 6不支持你。然后转到＆gt; Java Built Path＆gt;图书馆如果你有Apache Tomcat v6.0 [Apache Tomcat v6.0]库，它就完成了。否则转到＆gt;添加库＆gt;服务器运行时＆gt;并选择Apache Tomcat v6.0并单击Ok。
