我尝试使用JPA和Struts的集成来构建应用程序.要做到这一点需要访问tomcat管理器.但是当我访问URL时,http://localhost:8080/manager/html它给我404错误.

我的tomcat-users.xml

<?xml version='1.0' encoding='cp1252'?>

  <tomcat-users>

    <role rolename="manager-gui"/>
    <role rolename="manager-script"/>
    <role rolename="manager-jmx"/>
    <role rolename="manager-status"/>

    <!--<user name="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status" />-->
    <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

    </tomcat-users>

提前致谢.

我正在开发 Struts 2 应用程序，毕竟我收到以下错误。
