These are all codes used in my client. It was successful to connect to Server from another client made by javascript.

wssUrl = "wss://localhost:8443/index"
this.client = new WebSocket(wssUrl);

I think that Java websocket Client's configuration should be modified or something is inserted to configuration. Do you have any ideas with this guys? Help me out.

did you found any solution to this issue

Your URL is missing a tailing slash. Should be wss://localhost:8443/index/.
