I am totaly new to Hibernate and stuck on this problem.

I want to create an extended EntityManager (J2SE). I get the following exception. I am clueless why it wants a JTA TransactionManager, I thought that JDBC is default.

The answer to this problem was in second chapter of documentation. I fill stupid now, I can't belive I missed it yesterday.

Some exerpts:

The entity manager type (JTA or resource-local) is defined at configuration time, when setting up the entity manager factory.

The configuration for entity managers both inside an application server and in a standalone application reside in a persistence archive. A persistence archive is a JAR file which must define a persistence.xml file that resides in the META-INF folder.

Transaction type is chosen in transaction-type attribute of persistence-unit element. Either JTA or RESOURCE_LOCAL (default JTA).
Code:
<persistence-unit name="smarthome" transaction-type="RESOURCE_LOCAL">

Hi,

You should add a new property in the persistence.xml file

If you are using JBoss:

<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>

otherwhise you can use this one :

<property name="hibernate.transaction.manager_lookup_class" value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup"/>

Hope it helps you.

Code:

<!-- persistence.xml file -->
<property name="hibernate.transaction.manager_lookup_class" value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup"/>

<!-- Jboss -->
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
