glassfish显示不了html文件,Glassfish websocket无法正常工作(示例代码)

我尝试使用websocket。作为我使用Glassfish的服务器，工作正常，但我有websocket的问题。

当我在控制台中使用javascript运行html时出现错误404

Gradle构建没有错误。当我在qazxsw poi(vagrant虚拟机)中运行应用程序时

抛出错误：

与'ws：// localhost：8080 / web / websocket'的WebSocket连接失败：WebSocket握手期间出错：意外响应代码：404

在glassfish中，在Context Root：web中添加应用程序

怎么了 ？你能帮助我吗？请。谢谢 ：)
