#RequestMapping(value="/register.do",method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)

ANY OTHER INFO REQUIRED, PLS LET ME KNOW

I had the same problem few days before, and I got bellow solution.
#Controller
#RequestMapping(value="/" )
public class CustomerController {
//do your stuff here
#RequestMapping(method=RequestMethod.GET)
public String login(ModelMap model){
//model.put("Info", new Customer());
return "/login";
}
//Rest of your stuff goes here
}
Since you have configured your Dispatcher servlet to handle your context in stead of all possibility which people generally do by adding this (/*), so above provided code snippet will work and redirect your context to /login which you want(if i'm not wrong). Cheers!!!!

I have access to file localhost:8080/resources/core/css/bootstrap.min.css
Can you help me?

I've configured access to my resources differently. For starters, I use annotations only. From there, I added a resource handler:
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}

I have changed servlet mapping from
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
to
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.html</url-pattern>
<url-pattern>*.htm</url-pattern>
<url-pattern>*.json</url-pattern>
<url-pattern>*.xml</url-pattern>
</servlet-mapping>
and it works

Returning object with EJB 3

I'm trying to work with the EJB 3, but I'm missing something.
Initially I created a stateless bean that I called through the controller of the mvc.
The bean contained a method that returned a String.
Now, I'm wiling to go to the next level, namely I'm trying to create a bean that returns an object instead of a string.
Persona.java
package com.pojo;
import java.io.Serializable;
public class Persona implements Serializable {
private static final long serialVersionUID = 1L;
String nome;
int eta;
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public int getEta() {
return eta;
}
public void setEta(int eta) {
this.eta = eta;
}
}
RitornaPersonaRemote.java
package com.demo.view;
import com.pojo.Persona;
public interface RitornaPersonaRemote {
public Persona getPersona();
}
RitornaPersona.java
package com.demo;
import com.demo.view.RitornaPersonaRemote;
#Stateless
#Remote(RitornaPersonaRemote.class)
public class RitornaPersona implements RitornaPersonaRemote {
public Persona getPersona(){
Persona p = new Persona();
p.setEta(18);
p.setNome("tizio");
return p;
