我的课程是：

@Stateful
@Name("seguridadACG")
public class SeguridadControllerBean implements SeguridadController, Serializable {

    private static final long serialVersionUID = 7838664976264342564L;          

    private String esRol;

    public String getEsRol(){
        this.esRol = "Productor";
        return this.esRol;
    }

}

在XHTML中，我把这段代码：

<h:outputText   value=" Productores" rendered="#{seguridadACG.esRol == 'Productor'}" />

有人......拜托！救命！感谢
