Luchosuseadicto: HelloWorld Spring 3.0 en Weblogic 10.3.6 + Netbeans 7.4

Para comenzar como requisito deben tener instalado el servidor J2EE para este caso el weblogic 10.3.6 mas el Netbeans 7.4 j2ee que tiene incluidas las librerias de Spring MVC.

Primer se crea un proyecto web

Seleccionamos el servidor y la raiz del contexto

En esta pestañan seleccionan el framework Spring MVC la version sera la 3.2.3 y tambien incluimos JSTL

En la configuracion se da el nombre del descriptor XML que contiene los despachadores y le damos la extencion que van a tener las paginas en las URL, aunque sean paginas JSP se mostrara en la URL el *.htm

una vez creado el proyecto

Luego creamos un package para el controlador:

y agregamos la clase controlador.

package cl.allware.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 *
 * @author luxo
 */
@Controller
@RequestMapping("/welcome")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
 public String printWelcome(ModelMap model) {
 
  model.addAttribute("message", "Spring 3 MVC Hello World");
  return "hello";
 
 }
    
}

Ahora para poder resolver el controlador necesitamos agregar unas lineas en el despachador XML:

Y por ultimo el descriptor WEB.XML


    
        contextConfigLocation
        /WEB-INF/applicationContext.xml
    
    
        org.springframework.web.context.ContextLoaderListener
    
    
        dispatcher
        org.springframework.web.servlet.DispatcherServlet
        2
    
    
        dispatcher
        *.htm
    
    
        
            30
        
    
    
        redirect.jsp

En la capa vista crear una pagina :

<%-- 
    Document   : hello
    Created on : 03-02-2014, 10:45:49 AM
    Author     : luxo
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>


    
        
        JSP Page
    
 
 
Message : ${message}

ahora al hacer deploy en el servidor deberia aparecer el siguiente mensaje:
