I believe Sybase EA Server implements the necessary specifications... it's just a matter of what I specify below for the manager_lookup_class:

<property name="connection.datasource">java:/comp/env/jdbc/quoting</property>
<property name="transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
<property name="transaction.manager_lookup_class">**********</property>
<property name="dialect">net.sf.hibernate.dialect.SybaseDialect</property>

Can anyone help?
Thanks,
Brian

There is no build in transaction manager loopkup class for your case. See the code for other transaction manager lookup class, it is not difficult. You can create your own one for sybase and post it on jira for addition in hibernate
