Websocket Client Could not find an implementation class
javax.websocket api is only the specification don't have full implementation you may need to take the jar file tyrus-standalone-client-1.9.jar and try the same example that should solve your problem. i tested with my example and it is working fine.
hope this will help you.
I think the RuntimeException
you are experiencing is fortunately not generated by any direct coding fault of your own.
The method getWebSocketContainer()
, as described here, simply tries to load other classes and get the static instance of the ContainerProvider
in the server.
The method looks for the
ContainerProvider
implementation class in the order listed in theMETA-INF/services/javax.websocket.ContainerProvider
file, returning theWebSocketContainer
implementation from theContainerProvider
implementation that is notnull
.
This, unfortunately, means that your project is not configured correctly. Double check to make sure this file is included in your project's build path.
If other projects you are looking at are using the Maven dependency you described, I would try to set up your project to do the same.
Hope this helped!
