Thanks for doing some checking. I have been trying some of the Seam 2.0.0 demos (deploying to my 4.2.2 JBoss) and tutorials and ran seam-gen using my database. I got this to work. And in the set of generated files I see a persistence.xml and a components.xml. I think I see some interesting bits: In the generated persistence.xml I see: <persistence-unit name="AfmsttModernizationSeam"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/AfmsttModernizationSeamDatasource</jta-data-source> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> | <property name="hibernate.hbm2ddl.auto" value="validate"/> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.format_sql" value="true"/> | <property name="jboss.entity.manager.factory.jndi.name" value="java:/AfmsttModernizationSeamEntityManagerFactory"/> | </properties> | </persistence-unit> and in components.xml I see: <persistence:managed-persistence-context name="entityManager" | auto-create="true" | persistence-unit-jndi-name="java:/AfmsttModernizationSeamEntityManagerFactory"/> | These seem like config options that may help the wiring to complete the circuit if I add them in the right place in my war file.
