一个关于线程池的问题。。大家帮看看代码

用socket做个通讯这个是服务端为什么就接受不到客户端发送的数据呢？？？
大家帮我写一个客户端吧。。。。。

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.concurrent.*;

public class imServer{

private int port=8000;
private ServerSocket server;
private ExecutorService esc;
private int pool_size=4;
public imServer() throws Exception{
server =new ServerSocket(port);
esc=Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors()*pool_size);

}
public void server() {
Socket sc=null;
while(true){
try {
sc=server.accept();
try {
Thread.sleep(1000);
} catch (InterruptedException e) {

e.printStackTrace();
}
esc.execute(new Handler(sc));
} catch (IOException e) {

e.printStackTrace();
}

}
}
public static void main(String s[]){
try {
new imServer().server();
} catch (Exception e) {

e.printStackTrace();
}
}
}

class Handler implements Runnable{
private Socket sc=null;
static String msg=null;
DataInputStream read;
static DataOutputStream write;
public Handler( Socket sc) throws IOException{
this.sc=sc;
read=getReader(sc);
write=getWriter(sc);
}
public void run(){
try{
System.out.print(1230);
Thread.sleep(1000);
while(true){
msg=read.readUTF();
System.out.print(msg);
new Thread(new write()).start();
}
}catch(Exception e){
e.printStackTrace();
}finally{
try{
if(sc!=null)sc.close();
}catch(Exception e){
e.printStackTrace();
}
}
}
public static void send(){
if(!msg.equals(null)){
try {
write.writeUTF(msg);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private DataOutputStream getWriter(Socket sc) throws IOException{

return new DataOutputStream(
new BufferedOutputStream(sc.getOutputStream()));
}
private DataInputStream getReader(Socket sc) throws IOException{

return new DataInputStream(new BufferedInputStream(sc
.getInputStream()));
}
}
class write implements Runnable{
public void run(){
Handler.send();
}

}

怎么接收不到信息？

你随便另外写一个测试用例跑客户端就可以啊，你不会是把客户端代码放在你new imServer().server(); 后面吧，那肯定是执行不到的

public class As extends TestCase {
public void test(){
try{
Socket socket = new Socket("127.0.0.1", 8000);
DataOutputStream out = new DataOutputStream(socket.getOutputStream());

while (true) {
out.write("hello world".getBytes());
}
}catch(Exception e) {

}
}

单线程的我会。。。。
到了多线程用到线程池就有问题了他不报错也接受不到信息郁闷。。。
