我的问题，使用此代码解决：

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

     StreamConnection connection = (StreamConnection) 
     Connector.open("socket://IP:Port"); 

     PrintStream output = 
     new PrintStream(connection.openOutputStream()); 

     output.println("Request"); 
     output.flush(); 

     InputStream in = connection.openInputStream(); 
     int ch; 
     String recx; 

     while((ch = in.read()) != 13) 
     { 
     recx = recx + (char)ch; 
     } 


     in.close(); 
     output.close(); 
     connection.close();
