trying to make legacy non-spring servlets access spring wired services (https://stackoverflow.com/questions/28592841/nosuchbeandefinitionexception-when-trying-to-use-spring-with-jersey)

LegacyServlet

package com.sample.test

import java.io.IOException;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public class LegacyServlet extends HttpServlet {

    public void init(ServletConfig config) throws ServletException {
        super.init(config);
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());
        //TestJdbc test = (TestJdbc) ctx.getBean("testJdbc");
        
        String [] beans = ctx.getBeanDefinitionNames();

        ServletOutputStream os = response.getOutputStream();
        os.println("length: " + beans.length);  // prints 0 length
        os.flush();
    }
}
