Using the Hibernate Configuration Wizard in MyEclipseIDE 5.1.1GA I created the following configuration that specifies a MySQL datasource setup.

I believe my configuration for a datasource is correct for Hibernate. Its included below.

When I deploy my EAR and run the application (deploy on JBOSS 4.0.4) I get the following in the log:

08:17:00,190 INFO [TransactionManagerLookupFactory] instantiating TransactionManagerLookup: net.sf.hibernate.transaction.JBossTransactionManagerLookup
08:17:00,198 ERROR [TransactionManagerLookupFactory] Could not instantiate TransactionManagerLookup
java.lang.ClassNotFoundException: No ClassLoaders found for: net.sf.hibernate.transaction.JBossTransactionManagerLookup

I’m not sure what I could be missing. I’ve copied the hibernate jars to the <server>/lib directory in my JBOSS distribution so they should be there. I wasn’t sure where the JBossTransactionManagerLookup class lives.

<!– Generated by MyEclipse Hibernate Tools. –>
<hibernate-configuration>

<session-factory>
<property name=”connection.datasource”>java:DefaultDS</property>
<property name=”show_sql”>true</property>
<property name=”hibernate.transaction.manager_lookup_class”>net.sf.hibernate.transaction.JBossTransactionManagerLookup</property>
<property name=”hibernate.transaction.factory_class”>

</session-factory>

</hibernate-configuration>

Here is the property set I came up with that seemed to work for specifying a DataSource connection to Hibernate in MyEclipseIDE.

Not that it is important, but the DB is MySQL 5 and the Application Server is JBOSS 4.0.4.

Note: I did not use the wizard.

<property name=”show_sql”>true</property>
<property name=”hibernate.connection.provider_class”>org.hibernate.connection.DatasourceConnectionProvider</property>
<property name=”hibernate.connection.datasource”>java:/DefaultDS</property>
<property name=”hibernate.transaction.factory_class”>org.hibernate.transaction.JTATransactionFactory</property>
<property name=”hibernate.transaction.manager_lookup_class”>org.hibernate.transaction.JBossTransactionManagerLookup</property>
<property name=”hibernate.transaction.flush_before_completion”>true</property>
<property name=”hibernate.transaction.auto_close_session”>true</property>
<property name=”dialect”>org.hibernate.dialect.MySQLInnoDBDialect</property>

jcorbin,
The issue was that you were specifying the old Hibernate 2.x package class using net.sf.*, Hibernate refactored to org.hibernate.* I believe either in late 2.x or early 3.x (I could be wrong). But either way you got it.

Thanks for following up.
