このリンクをたどって、tomcatを使用してwebsocketサーバーを作成しました。Websocket にアクセスしようとすると、Firefox は接続を確立できないと言いました。
これが私のコードです
public class WsChatServlet extends WebSocketServlet
{
private static final long serialVersionUID = 1L;
private static ArrayList<MyMessageInbound> mmiList = new ArrayList<MyMessageInbound>();
@Override
protected StreamInbound createWebSocketInbound(String string) {
System.out.println("CreateWebSocketInbound()");
return new MyMessageInbound();
}
private class MyMessageInbound extends MessageInbound
{
WsOutbound myoutbound;
@Override
protected void onBinaryMessage(ByteBuffer bb) throws IOException {
System.out.println("onBinaryMessage()");
}
@Override
protected void onTextMessage(CharBuffer cb) throws IOException {
System.out.println("Accept Message : "+ cb);
for (MyMessageInbound mmib : mmiList)
{
CharBuffer buffer = CharBuffer.wrap(cb);
mmib.myoutbound.writeTextMessage(CharBuffer.wrap("Hello!"));
mmib.myoutbound.flush();
}
}
@Override
protected void onOpen(WsOutbound outbound) {
System.out.println("onOpen()");
try {
System.out.println("Open Client.");
this.myoutbound = outbound;
mmiList.add(this);
outbound.writeTextMessage(CharBuffer.wrap("Hello!"));
} catch (IOException ex) {
Logger.getLogger(WsChatServlet.class.getName()).log(Level.SEVERE, null, ex);
}
}
@Override
protected void onClose(int status) {
System.out.println("Close Client.");
mmiList.remove(this);
}
}
