[jboss-user] [JBoss Seam] - Re: problem configuring SMPC

[amitev]

I've added 


  |   <core:entity-manager-factory persistence-unit-name="SeamGenProject" name="entityManagerFactory" />
  |     
  |     <core:managed-persistence-context name="em"
  |                                       auto-create="true" 
  |                                       entity-manager-factory="#{entityManagerFactory}"/>

But now i have another exception now:
