So, I'm trying to set up a web server, using Ubuntu Server 14.04 and Apache Tomcat 7, but when I deploy my webapp, whenever I try to call a bean, I get the following error:
javax.el.PropertyNotFoundException: /usuario/login.xhtml @18,83 value="#{usuarioBean.obj.email}": Target Unreachable, identifier 'usuarioBean' resolved to null

</web-app>The thing is that if I deploy the .war file to Wildfly, it works correctly, the problem happens only using Tomcat7.
Using JDK 8u77, Tomcat7, Wildfly 9.0.2 Final, Primefaces v5.3, JSF 2.2

}I Think this question is not duplicated. I have seen lot's of problems with the ManagedBeans, but not one like mine, since it works on Wildfly 9.0.2 Final but doesn't work on Tomcat 7
