Server startup error: interface org.apache.catalina.Lifecycle not found

Hi! This is probably a dependency configuration issue, but I'm needing a hand to solve it.

I have 2 applications generated from the jboss javaee6 ear archetype (generates parent + ear + web + ejb modules). With the same code, except for the artifact ids.

The picketlink configuration for both is also different. I'm trying to configure a scenario like the quickstart apps: An application as the service provider (SP) and another as the identity provider (IDP).

The SP is configured like the "employee" quickstart app, and the IDP is configured like the "idp" quickstart app.
The SP shows no errors during the JBoss startup, but the IDP shows the following error:

Normally I would think of this as a dependency problem. But the SP load successfully, and the SP declares the "org.picketlink.identity.federation.bindings.tomcat.sp.ServiceProviderAuthenticator" Valve, which extends, indirectly, the class "org.apache.catalina.authenticator.FormAuthenticator".

Any clues?

Additional info:

When deployed as an WAR, the server starts up successfully. But this scenario doesn't fit my needs.
How to fix it for an EAR package (witha a WAR module and an EJB module)?
