I have a web application connected to a MySQL database.
This application implements the Frameworks Spring and Hibernate, and it has the following architecture:
In the file getGraph.jsp I have this code:
<%@page import="org.springframework.beans.factory.annotation.Autowired"%> <%@page import="com.google.gson.*"%> <%@page import="com.fdl.entity.*"%> <%@page import="com.fdl.dao.*"%> <%@page import="java.io.PrintWriter"%> <%@page import="org.springframework.context.support.ClassPathXmlApplicationContext" %> <%@page import="org.springframework.context.ApplicationContext" %> <% response.setContentType("application/json;charset=UTF-8"); Gson gson = new Gson(); ApplicationContext context = new ClassPathXmlApplicationContext("/applicationContext.xml"); FdlDao fdlDao=(FdlDao) context.getBean("fdlDao"); Graph graph = fdlDao.getGraph2(); out.print(gson.toJson(graph)); %> But when I run the code I get this error:
