Answer 1

您剪切/粘贴了大量的错误信息......但我想你忽略的事项:)

看看这个链接的部分：

• tomcat and netbeans deployment errors

1）他们使用的是NetBeans（您正在使用Eclipse--但可能并不重要）

2）他们得到了完全相同的回溯，你上面显示：

    at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:787) 
    .... 

3），但他们也表现出了追溯的重要组成部分：

Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getSessionCookieConfig()Ljavax/servlet/SessionCookieConfig; 
    at org.apache.catalina.deploy.WebXml.configureContext(WebXml.java:1308) 
    at org.apache.catalina.startup.ContextConfig.webConfig(ContextConfig.java:1343) 
    at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:896) 

4）本例中的根本原因是代码使用了在Java 6中引入的getSessionCookieConfig()，但他们无意中部署了一个早期的Java6版本的servlet.jar。解决方案是仔细检查他们的所有部署，确保部署正确的.jar。
