[b]Já passei por esse problema e ainda não consegui resolver.

Utiliso o Session do hibernate para fazer a consulta na autenticação.

Se conseguir resolver, posta ai.

Abraço.[/b]

caraaaa, resolvi usando hibernate. Segue abaixo a solução:

<persistence:hibernate-session-factory name="hibernateSessionFactory"/>

	<persistence:managed-hibernate-session name="emDataBase" auto-create="true" session-factory-jndi-name="java:/EmSessionFactory"/>

<session-factory name="java:/EmSessionFactory">
  <property name="transaction.flush_before_completion">true</property>
    <property name="connection.release_mode">after_statement</property>
    <property name="transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
    <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
    <property name="connection.datasource">java:/SeuDatasource</property>
    
  <property name="hibernate.connection.driver_class">org.hibernate.dialect.PostgreSQLDialect</property>
  <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/postgres</property>
  <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
  <property name="hibernate.connection.username">postgres</property>
  <property name="hibernate.connection.password">admin</property>
  <property name="hibernate.show_sql">false</property>
  <property name="hibernate.hbm2ddl.auto">update</property>
  <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
 </session-factory>

e nas suas classes, vc pode chamar:

@In Session emDataBase;

prontinho, agora não vem mais nulo. :D

Dá uma olhada também nos exemplos que vem junto com o Seam… Eles ajudam bastante para se aprender como faz, e ainda tem algumas explicações sobre alguns exemplos na documentação oficial.

Abraços.

EDIT: coloca [RESOLVIDO] no tópico pra ajudar quem procura! :smiley:
