JSP发送短信信息，调用Java类方法

Question

谢了这样一个类方法 ，我想要在JSP调用，并且执行这个类方法

package javaapplication;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.filter.HTTPBasicAuthFilter;
import com.sun.jersey.core.util.MultivaluedMapImpl;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ws.rs.core.MediaType;

import org.json.JSONException;
import org.json.JSONObject;
/**

  public class Api {
  public static void main(String[] args) {
  Api api = new Api();
  String httpResponse = api.testSend();
  try {
  JSONObject jsonObj = new JSONObject( httpResponse );
  int error_code = jsonObj.getInt("error");
  String error_msg = jsonObj.getString("msg");
  if(error_code==0){
  System.out.println("Send message success.");
  }else{
  System.out.println("Send message failed,code is "+error_code+",msg is "+error_msg);
  }
  } catch (JSONException ex) {
  Logger.getLogger(Api.class.getName()).log(Level.SEVERE, null, ex);
  }

  httpResponse =  api.testStatus();
  try {
      JSONObject jsonObj = new JSONObject( httpResponse );
      int error_code = jsonObj.getInt("error");
      if( error_code == 0 ){
          int deposit = jsonObj.getInt("deposit");
          System.out.println("Fetch deposit success :"+deposit);
      }else{
          String error_msg = jsonObj.getString("msg");
          System.out.println("Fetch deposit failed,code is "+error_code+",msg is "+error_msg);
      }
  } catch (JSONException ex) {
      Logger.getLogger(Api.class.getName()).log(Level.SEVERE, null, ex);
  }
  

  }

  private String testSend(){
  // just replace key here
  Client client = Client.create();
  client.addFilter(new HTTPBasicAuthFilter(
  "api","key-9e434e0d08c4154762378561143a1f5c"));
  WebResource webResource = client.resource(
  "http://sms-api.luosimao.com/v1/send.json");
  MultivaluedMapImpl formData = new MultivaluedMapImpl();
  formData.add("mobile", "sMSPhone");
  formData.add("message", "验证码：逗比【铁壳测试】");
  ClientResponse response = webResource.type( MediaType.APPLICATION_FORM_URLENCODED ).
  post(ClientResponse.class, formData);
  String textEntity = response.getEntity(String.class);
  int status = response.getStatus();
  //System.out.print(textEntity);
  //System.out.print(status);
  return textEntity;
  }

  private String testStatus(){
  Client client = Client.create();
  client.addFilter(new HTTPBasicAuthFilter(
  "api","key-9e434e0d08c4154762378561143a1f5c"));
  WebResource webResource = client.resource( "http://sms-api.luosimao.com/v1/status.json" );
  MultivaluedMapImpl formData = new MultivaluedMapImpl();
  ClientResponse response = webResource.get( ClientResponse.class );
  String textEntity = response.getEntity(String.class);
  int status = response.getStatus();
  //System.out.print(status);
  //System.out.print(textEntity);
  return textEntity;
  }
  }

我目前的理解，后台一个方法，前端jsp页面出发之后调用，那就是前后端通信。ajax异步，或者form表单提交，反正使用http请求到后台出发方法就好了。前端一般就是填入条件。
