Hello everyone!

I'm trying to setup a jboss seam configuration with tomcat 6.0. Based on 'jboss-seam-jpa' example. And now almost everything working :)

I've solved a bunch of issues by searching in the forum, but this one I can't solve.

When I'm try to inject entityManager on beans that extends classes of seam framework, such as EntityQuery or EntityHome, I'm getting this error:

org.jboss.seam.InstantiationException: Could not instantiate Seam component: carteiraHome
     at org.jboss.seam.Component.newInstance(Component.java:2106)
     at org.jboss.seam.Component.getInstance(Component.java:1988)
...
Caused by: java.lang.IllegalStateException: entityManager is null
     at org.jboss.seam.framework.EntityHome.create(EntityHome.java:33)
     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
     at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
...

Here's my component.xml
