使用企信通api遇到的问题

[firstapril]

代码

package com.linkage.netmsg.server;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;


import com.linkage.netmsg.NetMsgclient;

public class IM {


static OutputStream out;

static InputStream in = null;

public static boolean result;


public static void main(String[] args) throws IOException{

NetMsgclient client = new NetMsgclient();


ReceiveMsg receiveMsg = new Receive();


client = client.initParameters("218.94.58.243", 9005, "username", "password",receiveMsg);

try {


boolean isLogin = client.anthenMsg(client);
if(isLogin)System.out.println("login sucess");

for(int i =0 ; i < 30;i++)
{


client.sendMsg(client, 0, "165616161", "test", 1);


}


client.closeConn();


} catch (Exception e1) {
e1.printStackTrace();
}
System.out.println(result);

}



}

lz 仔细从这里检查吧at com.linkage.netmsg.server.IM.main(IM.java:41)

41行 是 client.sendMsg(client, 0, "165616161", "test", 1);
不知道哪错了
