Offline test of Servlets

Easy way to test Servlest is to use springs mocks.

Eg.

@Test
public void testService() throws Exception {
   System.out.println("service");

   MockHttpServletRequest request = new MockHttpServletRequest();
   MockHttpServletResponse response = new MockHttpServletResponse();

   XmlServiceServlet servlet = new XmlServiceServlet();

   new XmlServiceServlet().doGet(request, response);
      
   System.out.println(response.getContentAsString());
}

Just at folling to the pom
