這是我的配置struts-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

  </action>
 </action-mappings>

 <message-resources
  parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>

 錯誤提示﹕

javax.servlet.jsp.JspException: Cannot find bean: "personList" in any scope

 

Answer 1

你jsp里面有用到personList？struts-config.xml配置文件里，根本就体现不出来你有没有personList这个东西。frombean贴出来，还是有你action贴出来，才能看出来，你到底有没有把personList这个东西放到 any scope。
