Question

我正试图使https://www.oracle.com/webfolder/technetwork/tutorials/obe/java/HomeWebsocket/WebsocketHome.html的旧Java 7 EE WebSocket应用程序在Payara Server 5.184 #badassfish（内部版本89）中工作

但是，WebSocket（@ServerEndpoint）无法实例化。

Severe:   Exception in thread "glassfish-web-async-thread-1"  Severe: 
java.lang.NullPointerException  at
org.apache.catalina.connector.InputBuffer$ReadHandlerImpl.processAllDataRead(InputBuffer.java:492) at
org.apache.catalina.connector.InputBuffer$ReadHandlerImpl.access$800(InputBuffer.java:385) at

java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at 
java.lang.Thread.run(Thread.java:748)

通过启用CDI开发模式，我会看到：

WARN:   WELD-001703: Unable to determine the @Intercepted Bean<?> for
[UnbackedAnnotatedField] @Inject @Intercepted private
 org.jboss.weld.probe.InvocationMonitor.interceptedBean WARN:

com.magicpigeon.websocket.DeviceWebSocketServer$Proxy$_$$_WeldSubclass.<init>(Unknown Source) at
sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

DeviceWebSocketServer是我的@ServerEndpoint类。是否有与CDI相关的错误？我会缺少什么？。

代码在这里：https://github.com/DanielMerchan/WebsocketHome（如果有人想尝试一下）。过去，这在我以前使用Glassfish的Netbeans中起作用（不记得版本）。

谢谢。

如果我保留Java EE 7，则可以使用。不知道升级到Java EE 8会发生什么。

无法使WebSocket在Payara 5.1中工作
