I'm doing a Webapp that retrieves some information from a database and stores it in a Java bean using the "request" as context ,
POST method sends the table's information when executed.
I'd like to know if it would be better to create the bean as a servletContext to avoid instantiating it every time there is a request from the clients and hopefully reduce the time my application process the requests. I haven't found information regarding using Java beans as ServletContext .
Thanks in advance!
the original code
using Request:
public class ControleurServlet2 extends HttpServlet {
public void init() throws ServletException {
//Empty
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//... ... ...
//Instantiation des Objects de chaque Request envoyé par le Client
ModelEtagere model1=new ModelEtagere();
request.setAttribute("model",model1);//Envoi de Model Bean vers la page JSP
this.getServletContext().getRequestDispatcher(VUE).forward(request, response); }
the code using ServletContext:
public class ControleurServlet2 extends HttpServlet {
//Initialisation bean Model1
ModelEtagere model1;
@Override
public void init() throws ServletException {
metier= new MagasinMetierImpl();
model1=new ModelEtagere();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//ServletContext
ServletContext context= getServletContext();
// ... ... ...
context.setAttribute("model",model1);//Envoi de Model1 Bean vers la page JSP
this.getServletContext().getRequestDispatcher(VUE).forward(request, response);
}
