to do so each <code>JpaEndpoint</code> will auto create their own instance of 
<code>TransactionManager</code> which most often is not what you 
want.</p><p>For example, you can instantiate a JPA component that references 
the <code>myTransactionManager</code> transaction manager, as follows:</p><div

from the <a shape="rect" href="registry.html">Registry.</a> If Camel won't find 
any <code>TransactionManager</code> instance registered, it will also look up 
for the&#160;<code>TransactionTemplate</code> and try to 
extract&#160;<code>TransactionManager</code> from it.</p><p>If none 
<code>TransactionTemplate</code> is available in the registry, 
<code>JpaEndpoint</code> will auto create their own instance of 
<code>TransactionMan
 ager</code> which most often is not what you want.</p><p>If more than single 
instance of the <code>TransactionManager</code> is found, Camel will log a 
WARN. In such cases you might want to instantiate and explicitly configure a 
JPA component that references the <code>myTransactionManager</code> transaction 
manager, as follows:</p><div class="code panel pdl" style="border-width:
