<p>In client/server mode the TCP connection between the client and the server can also be used to send messages from the client to the server.</p>
<p>Possible usecases could be:</p>
<ul>
<li>shutting down and restarting the server</li>
<li>triggering server backup</li>

</ul>
<p>Here is some example code how this can be done.</p>
<p>First we need to decide on a class that we want to use as the message. Any object that is storable in db4o can be used as a message, but strings and other simple types will not be carried (as they are not storable in db4o on their own). Let's create a dedicated class:</p>

Let's simply print out all objects that arrive as messages. For the following we assume that we already have an ObjectServer object, opened with <a href="embedded.html" class="wikiLink">Db4o.openServer()</a>.</p>
