Ya, it was removed in 2.0 beta and was replaced by the
"transaction-management-enabled" attribute

Unfortunately it is not out yet. Feel free to checkout the latest from CVS and
build your own snapshot though.

org.jboss.seam.transaction.Transaction, which always exists the method
getUserTransaction with a runtime exception: I am forced to disable the seam tx
management in components.xml with <core:init debug="true"
transaction-management-enabled="false"/> to get rid of the problem. But I think
I am then only relying on the spring tx management and might get
LazyInitilizationException. Is my understanding right?
So first of all in 2.0.0 CR1 you will be able to use a spring TM as a Seam TM
and will be able to enable "transaction-management-enabled". For now though
who is doing the transaction management has nothing to do with getting
LazyInitializationExceptions. What "transaction-management-enabled" disabled
will mean is that when you wish to flush() your conversation scoped PC it will
be best to do it inside of a Service call with @Transactional.
Otherwise your configuration looks fine otherwise. A couple of points:
1. You don't need to inject a dataSource into your JpaTransactionManager. I'm
not sure if it will mess things up or not but I know it is not necessary.
2. Make sure your components.xml has your entityManager definition:
| <persistence:managed-persistence-context name="entityManager"
| auto-create="true"
| entity-manager-factory="#{entityManagerFactory}"/>
And uncomment and rename your SeamManagedEntityManagerFactoryBean to something
like:
| <bean id="seamEntityManagerFactory"
|
class="org.jboss.seam.ioc.spring.SeamManagedEntityManagerFactoryBean">
| <property name="persistenceContextName" value="entityManager" />
| </bean>
And make sure that you use your seamEntityManagerFactory with your
JpaTransactionManager like:
| <bean id="transactionManager"
| class="org.springframework.orm.jpa.JpaTransactionManager">
| <property name="entityManagerFactory"
| ref="seamEntityManagerFactory" />
| </bean>
|
Otherwise read over more closely the Seam+Spring docs regarding Persistence
contexts.
