Struts2初次配置启动tomcat出错

Question

开发环境：
Eclipse Java EE IDE for Web Developers.

Version: Helios Service Release 1
Build id: 20100917-0705

Tomcat 6.x log：

[/code]

web.xml如下：
[code="java"]
<?xml version="1.0" encoding="UTF-8"?>

Struts2Demo

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

[/code]

在xml中右键点击：org.apache.struts2.dispatcher.FilterDispatcher，可以进入FilterDispatcher类。

我在网上搜了下，提供的解决方案有：
1、导入commons-fileupload.jar和commons-io.jar包

2、将tomcat及jdk版本更新到struts2的需求，即5.5及1.5

3、添加struts2开发所需完整jar包

4、检查web.xml及struts.xml是否书写错误

5、将struts2相关包手动添加到classpath中
除了5我都试过，没有问题。
引入的jar包，见下图：

PS:我十分想将红圈里的那俩东西删掉，但是也不知道怎么搞。我是建立的Dynamic Web Project，建完之后就带着了，删不掉。

[quote]这个帖子中的配置界面怎么进入，我的情况很可能就是这个问题。

双击Servers面板的
Tomcat v6.0 Server at localhost

再点击Open launch configuration(打开运行配置)
