<p>Note that as of OpenEJB 3.1 you do not need to set the

automatically and will overwrite any "org.hibernate.transaction."

may have implemented untouched.</p>

<div class="paragraph">
<p>The result is that you can leave your
<code>hibernate.transaction.manager_lookup_class</code> property configured to your
production environment and OpenEJB will update it just for the scope
testing. On the other hand if you have implemented a custom
<code>org.hibernate.transaction.TransactionManagerLookup</code> strategy it will
always be used and never replaced by OpenEJB.</p>

<p>A custom implementation of Hibernate&#8217;s <em>TransactionManagerLookup</em>
