dojo 怎么样实现和server端的交互?那么它有自己的一套AJAX框架的内容

server端的代码
package hb.servlet; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class DojoAjax extends HttpServlet { protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { System.out.println("do get"); } protected void doPost(HttpServletRequest request,IOException { System.out.println("do post"); } }
