SSH框架下的404错误
即便是新建的jsp文件在此工程下也会404错误。
web.xml里面关于struts及其过滤器的两段代码删除后就好了：它们是：
<!-- struts2的过滤器 -->
  <filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
和
<!-- Struts2中导入spring监听 -->
  <listener>
  <listener-class>
  org.springframework.web.context.ContextLoaderListener
  </listener-class>
  </listener>
tomcat启动时有error提示，我怀疑与错误有关系,提示如下：
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cubeDateDictionaryEntriesDAOTarget' defined in file [F:\tomcat6.0\webapps\CubeEIS\WEB-INF\classes\applicationContext-dao.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/transaction/TransactionManager

这里面的applicationContext-dao.xml内容如下（第一个bean定义就是出问题的，我注释后就会提示第二个bean错误了）：
