Error message

I got the following message when launching a seam application in JBoss 4.2.2 GA

FATAL [application] JSF1029: The specified InjectionProvider implementation 'org.jboss.web.jsf.integration.injection.JBossInjectionProvider' does not implement the InjectionProvider interface.

Here's the stack trace which follows the above error:

Analysis

The problem is causes by two versions of jsf-api and jsf-impl jars at runtime. The application included one version and the other version was coming from Jboss container.
