Dies sind alle Codes, die in meinem Client verwendet werden. Es war erfolgreich, von einem anderen Client, der durch Javascript gemacht wurde, eine Verbindung zum Server herzustellen.
Ich denke, dass Java WebSocket Client-Konfiguration geändert werden sollte oder etwas in die Konfiguration eingefügt wird. Hast du irgendwelche Ideen mit diesen Jungs? Hilf mir aus.
