I made WebSocket Echo Client on JavaFX before.(see here) This time Web Scoket on WebView in JavaFX. The code is very simple (see code 1). Using WebView and WebEngine, loading EchoClient.html(see code 2). But when executing this on JavaFX7, it does not work. Nothing happen after clicking the open button, the close button nor the send button. This problem was already reported in JavaFX jira.(F.Y.R h
