  1.   

    Unable to load jar:file:/D:/setup/tomcat/apache-tomcat-6.0.14/webapps/Apparition/WEB-INF/lib/struts2-core-2.1.8.1.jar!/struts-default.xml - [unknown location
    struts2-core-2.1.8.1.jar没有引入，看一下lib里面有没有这个包，没有的话，拷到lib包里。

    Caused by: java.net.ConnectException: Connection timed out: connect连接超时,数据库服务启动了吗?

    你用的STRUTS2的包是官网下载的么？最好是打包下次性下载，里面包含所有的组件。我觉得应该是读取struts2-core-2.1.8.1.jar!/struts-default.xml 这个文件进行XML DTD或者Schema 验证时找不到对应的文件，它会去网络下上载对应的DTD或者Schema 文件。。而对应的DTD或者Schema 文件网络上不是存在的所以出现网络连接异常。正常情况下不连网也是可以的它会去对应的JAR包里找DTD或者Schema 
      

  6.   

    struts.xml配置文件有么有放对地方，放在src下面
      

  7.   

    好像struts2 配置文件顶端的 <!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
      "http://struts.apache.org/dtds/struts-2.1.dtd">
    如果在不连网络的情况下需要改动么
