显然,org.apache.struts.action.ActionServlet中的Servlet名称"Action"存在问题.Unfurtunatley我不知道我做错了什么.你有个主意吗？许多事先提前.奥利

Answer 1

发生此错误是因为您的servlet-core jar不在运行时类路径上.如果你正在使用maven,

1. 打开您的EAR/Web项目属性
2. 点击"部署组装"
3. 点击"添加..."
4. 选择"Java Build Path Entries"
5. 点击"下一步"
6. 选择"Maven Dependencies"
7. 点击"完成"

如果不是maven,请确保放置jar的lib文件夹位于"Deployment Assembly".
