websocket连接不上、报错、自动关闭，求解

[asd8222687]

学WS遇到三个问题：
一：

描述：能够成功连上并调用onopen方法，并且能够收到服务器推送的消息，但是在send发送数据时，提示连接被关闭1002:An unrecoverable IOException occurred so the connection was closed
环境：window7+chrome/360浏览器+tomcat7
websocket初始化方法：

function WS(u, messageF) {
var ws = null;
var url = 'ws://localhost:8080/Auction/websocket';
if ('WebSocket' in window) {
ws = new WebSocket(url);
} else if ('MozWebSocket' in window) {
ws = new MozWebSocket(url);
}
ws.onmessage = function(m) {
messageF(m.data);
};
ws.onopen = function() {
messageF('Opened');
};
ws.onclose = function(e) {
messageF(e.code + ":" + e.reason);
};
ws.onerror = function(e) {
for ( var p in e) {
messageF(p + "=" + e[p]);
}
};
this.send = function(m) {
ws.send(m);
};
}

服务器WS：

public void onOpen(Session session, EndpointConfig conf) {
this.session = session;
RemoteEndpoint.Basic remoteEndpointBasic = session.getBasicRemote();
session.addMessageHandler(new WSMessageHandler(remoteEndpointBasic));
String message = String.format("* %s %s", nickname, "has joined.");
try {
session.getBasicRemote().sendText(message);//这条信息页面能收到
} catch (Exception e) {
}
}
public void onClose() {
String message = String
.format("* %s %s", nickname, "has disconnected.");
System.out.println(message);
}
public void onError(Throwable t){
System.out.println(t.toString());
}
}

二：
环境：android4.0+chrome+tomcat7，代码跟上面相同
描述：连不上WS，onopen方法没有被调用，onerror方法被调用，错误信息如下。之后调用onclose，正常关闭，关闭码为1006

三、
环境：android4.0+UC+tomcat7，代码跟上面相同
描述：连不上WS，onopen方法没有被调用，onerror方法也没被调用，onclose被调用，连接被正常关闭，关闭码为1006

测试用的浏览器都是支持WS的，求解啊
求大神，在线等……

function WS(u, messageF) {
        var ws = null;
        var url = 'ws://localhost:8080/Auction/websocket';
        if ('WebSocket' in window) {
                ws = new WebSocket(url);
        } else if ('MozWebSocket' in window) {
                ws = new MozWebSocket(url);
        }
        ws.onmessage = function(m) {
                messageF(m.data);
        };
        ws.onopen = function() {
                messageF('Opened');
        };
        ws.onclose = function(e) {
                messageF(e.code + ":" + e.reason);
        };
        ws.onerror = function(e) {
                for ( var p in e) {
                        messageF(p + "=" + e[p]);
                }
        };
        ws.send = function(m) {
                ws.send(m);//m在哪定义的
        };
}

你贴的服务器端并没有接受消息的OnMessage方法

[街头小贩]

endpointer的代码存根

import javax.websocket.EndpointConfig;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

/**
 *
 * @author xiaofanku
 */
@ServerEndpoint("/endpoint")
public class Hello {

    @OnMessage
    public String onMessage(String message) {
        //当客户端发来消息时在此处理
        return null;
    }

    @OnClose
    public void onClose() {
        //当连接关闭时调用
    }

    @OnOpen
    public void onOpen(Session session, EndpointConfig config) {
        //当有客户端连接时调用
    }

    @OnError
    public void onError(Throwable t) {
    }
    
}

不明白怎么写看一看这篇文章:https://netbeans.org/kb/docs/javaee/maven-websocketapi.html

我的聊天室程序，服务器端代码：

    @OnOpen  
    public void open(Session session) {  
        this.session = session;

        logger.info("*** WebSocket opened from sessionId " + session.getId());  
    }

    	String countMsg = connections.size() + "人同时在线";
        int startIndex = message.indexOf("!@#$%");
        String nikeName = message.substring(0, startIndex);
        String textMsg = message.substring(startIndex + 5);
