如何将pc上的本地tomcat服务器连接到真正的android设备上？

Question

我一直在将我的android设备连接到pc的本地tomcat服务器时遇到问题。以下是Android代码..

public class Nxtstp extends Activity implements OnClickListener { 

EditText txt; 
Button btn; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.nxtstp); 
    btn =(Button) findViewById(R.id.Ent); 
    btn.setOnClickListener(this); 
};  


class conn extends AsyncTask<Void, Void, Void> 
{ 

    @Override 
    protected Void doInBackground(Void... arg0) { 
     // TODO Auto-generated method stub 
     new Thread(new Runnable() { 
      public void run() { 
      try{ 
       URL url = new URL("http://10.0.2.2:8084/Wiremserv/servlet1"); 
       URLConnection connection = url.openConnection(); 


       //inputString = URLEncoder.encode(inputString, "UTF-8"); 
       String msg="Verify"; 


       connection.setDoOutput(true); 
       OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream()); 
       out.write(msg); 
       out.close(); 

       BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); 

       final String returnString="Verfied"; 
       final String ret = in.readLine(); 
       if(returnString==ret){ 
        Context cont = getApplicationContext(); 
        String ms="Connection verified"; 
        int dur=Toast.LENGTH_SHORT; 

        Toast tst = Toast.makeText(cont, ms, dur); 
        tst.show(); 

        Intent i = new Intent("com.lnct.wirem3.MAINSERV"); 
        startActivity(i); } 

       in.close(); 

       }catch (UnknownHostException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 


        } 

        }).start(); 
     return null; 
    } 

和下面的NetBeans servlet代码：

public class servlet1 extends HttpServlet { 



private static final long serialVersionUID = 1L; 

public servlet1() { 
    super(); 

} 

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 

    response.getOutputStream().println("Hurray !! This Servlet Works"); 

} 


@Override 
protected void doPost(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 


    try { 


     File song = new File("E:/Music/digit.mp3"); 
     URL url = song.toURI().toURL(); 
     Player player=Manager.createPlayer(url); 
     try { 
      int length = request.getContentLength(); 
      byte[] input = new byte[length]; 
         ServletInputStream sin = request.getInputStream(); 
         int c,count=0; 
         while ((c = sin.read(input, count, input.length-count)) != -1) { 
      count +=c; 
     } 
     sin.close(); 
      String str = new String(input); 
      response.setStatus(HttpServletResponse.SC_OK); 
      OutputStreamWriter writer = new OutputStreamWriter(response.getOutputStream()); 

       if("Verify".equals(str)){ 
        String st="Verified"; 
        writer.write(st); 
        writer.flush(); 
        writer.close(); 
       } 
     } 




     catch (IOException e) { 


      try{ 
       response.setStatus(HttpServletResponse.SC_BAD_REQUEST); 
       response.getWriter().print(e.getMessage()); 
       response.getWriter().close(); 
      } catch (IOException ioe) { 
      } 
     } 
    } catch (NoPlayerException ex) { 


     Logger.getLogger(servlet1.class.getName()).log(Level.SEVERE, null, ex); 
    } 
} 

}

现在

什么，我想的是，我想我的应用程序连接到这个servlet所以点击验证按钮后，我的新活动就会启动。该servlet只是比较字符串以发送验证消息给android设备。也请告诉我的方式使我的Android设备（三星Galaxy S提前GT-I9070）

重写此方法中的servlet上工作：

protected void service(HttpServletRequest arg0, HttpServletResponse arg1) 
    throws ServletException, IOException 

在这里把你doGet代码，它会正常工作。
