Question

I am new to Struts2 and am developing a web application with file upload option. 我是Struts2的新手，正在开发带有文件上传选项的Web应用程序。 Everything has been configured but when i run the module HTTP Status 404 error: The requested resource is not available. 一切都已配置，但是当我运行模块HTTP Status 404错误时：请求的资源不可用。 (Link: http://localhost:8080/File_Upload/index.jsp ). （链接： http://localhost:8080/File_Upload/index.jsp ）。 please find below my config, index.jsp 请在我的配置下找到index.jsp

You have to add in your struts.xml this action inside your default package 您必须在默认包中的struts.xml文件中添加此操作

<action name="index">
    <result>/index.jsp</result>
</action>

In this way when you'll try to open http://localhost/myapp/index it will return the index.jsp 这样，当您尝试打开http：// localhost / myapp / index时，它将返回index.jsp
