Answer 2

如果你的applicationContext.xml在web-inf下
那么在web.xml上因该有
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext.xml
</param-value>
</context-param>

Answer 3

可能原因：1. spring与hibernate的冲突.两个框架都依赖asm.jar包spring的版本是asm-2.23.jar.hibernate依赖的是asm.jar 
需要将asm-2.2.3.jar删除.没有删除的话会引起这样的异常 
2. hibernate与struts的冲突,两个框架都依赖common-collections.jar.hibernate的是common-collections-2.1.1.jar,struts的是common-collections.jar.需要将hibernate所依赖的common-collections-2.1.1.jar删除.没有删除的话会引起这个异常 
3. web.xml中没有配置
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
        /WEB-INF/applicationContext*.xml,classpath*:applicationContext*.xml
  </param-value>
 </context-param>
 <listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
 </listener>
5. jar包导入是否正确
Spring包（9个）: 
commons-dbcp.jar、commons-pool.jar、spring.jar、spring-beans.jar、 
spring-context.jar、spring-core.jar、spring-dao.jar、 
spring-hibernate3.jar、spring-web.jar。 struts2.0包（6个）:commons-logging-api-1.1.jar、freeer-2.3.8.jar 
ognl-2.6.11.jar、struts2-core-2.0.8.jar、 
struts2-spring-plugin-2.0.11.2.jar、xwork-2.0.3.jar hibernate包:myeclipse工具自动添加生成导入。 
还有就是数据库驱动包。
