一具初学者的问题，请指教？

我编写了一个网络通信的程序，一个服务器，一个是客户端程序，我想实现这样的功能，客户端连接到服务器，客户端通过用户输入信息发送给服务器，服务器再将原信息返回，客户端输出信息，然后又等待用户输入，现在是服务器端可以给客户端发信息，客户端也能接收，但客户端给服务器端发信息服务器端收不到，不知道为什么？有没有人愿意帮助我？谢谢！
服务器端程序：
import java.io.*;
import java.net.*;
public class ServerEx
{
public static void main(String args[])
{
ServerSocket svrSocket = null;
Socket clientSocket;
int nConnect = 0;
String str;
try
{
svrSocket = new ServerSocket(8000,5);
while(nConnect < 5)
{
clientSocket = svrSocket.accept();
ServiceClient(clientSocket);
nConnect ++;
}
}
catch(IOException ioe)
{
System.out.println("Error in ServerEx" + ioe);
}
}
public static void ServiceClient(Socket client) throws IOException
{
DataInputStream inbound = null;
DataOutputStream outbound = null;
try
{
inbound = new DataInputStream(client.getInputStream());
outbound = new DataOutputStream(client.getOutputStream());
String inputLine;
outbound.writeBytes("Welcome to connected the Server\n");
while((inputLine = inbound.readLine())!="exit")
{
System.out.println("The Server answered:" + inputLine);
outbound.writeBytes(inputLine);
}
}
finally
{
System.out.println("Cleaning up connections:"+client);
inbound.close();
outbound.close();
client.close();
}
}
}
客户端程序：
import java.io.*;
import java.net.*;
public class ClientEx
{
public static void main(String args[]) throws IOException
{
//Socket client = null;
String inputLine=null,rev = null;
BufferedReader buf = null;
InetAddress addr = InetAddress.getByName(null);
Socket client = new Socket(addr,8000);
DataInputStream in = new DataInputStream(client.getInputStream());
DataOutputStream out = new DataOutputStream(client.getOutputStream());
try
{
buf = new BufferedReader(new InputStreamReader(System.in));
inputLine = in.readLine();
System.out.print(inputLine + "\n");
inputLine = buf.readLine();
for(;;)
{
if(inputLine.equals("exit"))
break;
System.out.println("Your's input is " + inputLine );
out.writeBytes(inputLine);
rev = in.readLine();
System.out.println("The server's answer is " + rev);
inputLine = buf.readLine();
}
}
finally
{
in.close();
out.close();
buf.close();
client.close();
}
}
}
