+ <para>
+ By default there is no active transaction during a remoting request, so if you wish
to perform database updates
+ during a remoting request, you need to annotate the
<literal>@WebRemote</literal> method with
+ <literal>@Transactional</literal>, like so:
+ </para>

+ <programlisting><![CDATA[ @WebRemote
@Transactional(TransactionPropagationType.REQUIRED)
+ public void updateOrder(Order order) {
