关于J2ME与Servlet通信中的一些问题，在线跪求答案
现在正在做J2ME与Servlet之间通信的程序，但是在发送的时候总是有异常。下面是我的代码，希望各位高手指导指导。
public   class   httpGet   extends   MIDlet   implements   CommandListener   {
public   void   commandAction(Command   cmd,   Displayable   dis)   {

if(cmd   ==   downloadCommand)   {
http.setName(nameF.getString());
http.setPass(passF.getString());
synchronized(this){
notify();
}
}
}

package   src;

import   java.io.*;
import   javax.microedition.io.*;

public     class   HttpThread   implements   Runnable{
// private   String   url   =   "   ";
private   httpGet   midlet   =   null;
private   boolean   done   =   false;
public   static   final   String   HOST   =   "http://192.168.44.88:8080/do/servlet/Select? ";
public   static   final   String   HOST1   =   "http://localhost:8080/server/servlet/server ";
public   static   final   String   HOST3   =   "http://192.168.44.88:8080 ";
public   String   name   =   null;
        public   String   PassWrod   =   null;
public   HttpThread(httpGet   midlet)   {
this.midlet   =   midlet;
}

// public   void   setURL   (String   url)   {
// this.url   =   url;
// }

public   HttpConnection   openConnection()   throws   IOException   {
HttpConnection   conn   =   (HttpConnection)Connector.open(HOST1,Connector.READ_WRITE);      
return   conn;
}

public   void   setName(String   name){
this.name   =   name;
}

public   void   setPass(String   pass){
this.PassWrod   =   pass;
}

public   void   run()   {
while(!done)   {
synchronized   (midlet)   {
try{
try   {
midlet.wait();
}   catch   (InterruptedException   e)   {
//   TODO   Auto-generated   catch   block
e.printStackTrace();
}
if(!done)   {
HttpConnection   conn   =   openConnection();
conn.setRequestMethod(HttpConnection.POST);      
                                       
                                        conn.setRequestProperty( "IF-Modified-Since ", "15       Oct       2003       08:47:14       GMT ");      
                                        conn.setRequestProperty( "User-Agent ", "Profile/MIDP-2.0       Configuration/CLDC-1.1 ");

                                        conn.setRequestProperty( "Content-Type ", "application/x-www-form-urlencoded ");
