log4j socket用法 高手请指点一下

[princesshan]

按照该链接中的方法
进行log4j 发消息到socket端口，
但是如果不是用博文中作者提到的方法接受，另写了一个接受的socket，同一台机器，接受到的信息是一大堆乱码？
package com.test.Receiver;
import java.net.*;
import org.apache.log4j.Logger;
import java.io.*;
public class MultiUser extends Thread {
static Logger logger = Logger.getLogger(MultiUser.class.getName());
private Socket client;
public MultiUser(Socket c)
{
this.client = c;
}
public void run()
{
try
{
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
PrintWriter out = new PrintWriter(client.getOutputStream());
while(true)
{
String str=in.readLine();
logger.debug(str);

System.out.println(str);
if(str.equals("end"))
{
break;
}
}
client.close();
}
catch(IOException ex)
{

}
finally
{

}
}

public static void main(String[] args) throws IOException
{
// TODO Auto-generated method stub

ServerSocket server = new ServerSocket(4445);
while(true)
{
//transfer location change Single User or Multi User
MultiUser mu = new MultiUser(server.accept());
mu.start();
}

}

}

public void run() {
try {
ObjectInputStream ois = new ObjectInputStream(
new BufferedInputStream(client.getInputStream()));

LoggingEvent event;
while (true) {
// read an event from the wire
event = (LoggingEvent) ois.readObject();
String msg = event.getRenderedMessage();
System.out.println(msg);

}
} catch (Exception ex) {

} finally {

}
}
