  | There seems to be some conflicts in the Seam documentation.  Do you need a "entity-manager-factory" node as well?  In some places I've read where this configuration is needed (even though it never works for me):
  |    <core:managed-persistence-context name="entityManager"
  |   |                               auto-create="true"
  |   |                    entity-manager-factory="#{omegaEntityManagerFactory}"/>

  |   |    <core:entity-manager-factory name="omegaEntityManagerFactory" 
  |   |                persistence-unit-name="omega"/>
  | In Seam 1.2, which is the correct way to create the entityManager component when deploying to Tomcat?

I'm using the EntityQuery successfully, and in my components.xml I have

  | 	<core:managed-persistence-context name="entityManager" auto-create="true"
  | 		persistence-unit-jndi-name="java:/fbEntityManagerFactory" />

All of the Seam framework components (EntityController, Homes and Queries expect to find persistence-context named entityManger, though you can override these (look at the source, there's a getPersistenceContextName() method in each).

What exceptions are you seeing?
