    JSP not accessing my Beans

    Diego Y K Newbie
      Hi I'm really new on the Seam and JSF scenario and it's beeing a preety though but refreshing experience so far.

      At the moment i'm trying to make a simple Hello World like application without EJB or JPA.

      My configuration files are the following:

      faces-config.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xi="http://www.w3.org/2001/XInclude"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">
      <!--  adicionado par ao seam -->
      <lifecycle>
        <phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener>
      </lifecycle>
      </faces-config>

      `package bean;

      import javax.persistence.Entity;

      import org.jboss.seam.annotations.Name;

      @Entity
      @Name("user")
      public class User{
             
              protected String name= "hello";
             
              public String getNome() {
                      return name;
              }
             
              public void setNome(String name) {
                      this.name = name;
              }
      }

      The application is deployed successufully but whe I acces the url for the page I get no error nor output.
