For examples, see Chapter&nbsp;<a  href="JMSJ2EEex.html#wp78297">30</a>. In this application, the client is the sending component. To view this example in <code class="cCode">deploytool</code>, expand the <code class="cCode">SimpleMessageApp</code> node, then select <code class="cCode">SimpleMessageClient</code> from the tree view.</p><a name="wp79836"> </a><h3 class="pHeading2">Setting the Resource References</h3><a name="wp80488"> </a><p class="pBody">You use the Resource Refs tabbed pane to specify the connection factory references for the component.</p><div class="pSmartList1"><ol type="1" class="pSmartList1"><a name="wp79837"> </a><div class="pSmartList1"><li>In the tree view, select the client node.</li></div><a name="wp79838"> </a><div class="pSmartList1"><li>Select the Resource Refs tab.</li></div><a name="wp79839"> </a><div class="pSmartList1"><li>Click Add.</li></div><a name="wp79840"> </a><div class="pSmartList1"><li>In the Coded Name field, enter the name that matches the parameter of the <code class="cCode">lookup</code> method in the client's code.
