イメージファイルをサーバに直接送信する方法

Question

私はアンドロイドが新しく、イメージファイルを私のサーバに直接送信しようとしています。その方法はわかりません。私はPOSTメソッドを使用して私のサーバーでJAX-RS Restful Webサービスを使用しています。

ここに私のコード（Androidのコード）：

File myFile = new File("/path/to/file.png"); 
RequestParams params = new RequestParams(); 
try { 
params.put("image", myFile); 
UpdateProfilePicToServer(params); 
} catch(FileNotFoundException e) {} 

private void UpdateProfilePicToServer(RequestParams params) { 
    // Show Progress Dialog 
    prgDialog.show(); 
    // Make RESTful webservice call using AsyncHttpClient object 
    AsyncHttpClient client = new AsyncHttpClient(); 
    // client.setTimeout(20000); 
     client.post(URL, params, new AsyncHttpResponseHandler() { 
     @Override 
     public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { 
      // Hide Progress Dialog 
      prgDialog.dismiss(); 
      try { 
       // JSON Object 
       JSONObject obj = new JSONObject(new String(responseBody)); 
       // When the JSON response has status boolean value assigned with true 
       if (obj.getBoolean("status")) { 

        Toast.makeText(context.getApplicationContext(), "Saved", Toast.LENGTH_LONG).show(); 
       } 
       // Else display error message 
       else { 
        profilePic.setImageResource(R.drawable.profile_placeholder); 
        Toast.makeText(context, obj.getString("msg"), Toast.LENGTH_LONG).show(); 
       } 
      } catch (JSONException e) { 
       // TODO Auto-generated catch block 
       Toast.makeText(context, "Error Occured [Server's JSON response might be invalid]!", Toast.LENGTH_LONG).show(); 
       e.printStackTrace(); 
      } 
     } 
     @Override 
     public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) { 
      // Hide Progress Dialog 
      prgDialog.dismiss(); 
      // When Http response code is '404' 
      if (statusCode == 404) { 
       Toast.makeText(context, "Requested resource not found", Toast.LENGTH_LONG).show(); 
      } 
      // When Http response code is '500' 
      else if (statusCode == 500) { 
       Toast.makeText(context, "Something went wrong at server end", Toast.LENGTH_LONG).show(); 
      } 
      // When Http response code other than 404, 500 
      else { 
       Log.d("StatusCode", String.valueOf(statusCode)); 
       Toast.makeText(context, "Check your internet connection", Toast.LENGTH_LONG).show(); 
      } 
     } 
    }); 

} 

ここに私のウェブサービスコード（Javaの）：

public String post(@FormParam("accId") String accId, @FormParam("image") File image) throws Exception 
{ 
    try { 
     Statement chkUserStmt = DataAccess.conn.createStatement(); 
     String updatequery = "UPDATE ACCOUNT SET PROFILE_PICTURE = LOAD_FILE('" + image+ "') " 
           + "WHERE ACCOUNT_ID = '" + accId + "'"; 
     chkUserStmt.executeUpdate(updatequery); 
     chkUserStmt.close(); 
     return Utility.respJSON("ImageStore ", true, "Success");     
    } catch (Exception ex) { 
     Logger.getLogger(ImageStore.class.getName()).log(Level.SEVERE, null, ex); 
    }  
    return Utility.respJSON("ImageStore ", false, "Failure");    
}
