Adder:
Me sale el siguiente mensaje cuando despliego mi guerra con el Tomcat 7:
nested exception is java.lang.NoClassDefFoundError: javax/el/ELManager
He añadido <tomcat.version>7.0.61</tomcat.version>a mi pom.xml y ahora puede reproducir el error en mi entorno de desarrollo.
El error se produce después de la creación de frijol, los otros cambios que eran necesarios para obtener la guerra para funcionar hice.
Traté de cambiar mi pom.xml para que utilice versiones antiguas que podrían jugar bonito con Tomcat 7, pero no lograron eliminar el problema. No sé cuál es el paquete produce el problema.
Ver pom.xml:

Hriamnlfach:
de inicio de primavera 2.1.2 versión es compatible con cualquier contenedor de servlets compatible 3.1+.
Tomcat 7 no es una de ellas
de inicio de primavera docs
Utilizar Tomcat 8 o más allá http://tomcat.apache.org/whichversion.html
