if you want to do it with HTML table, you can write the following:
<f:view>
<table border="1">
<tr>
<td>
<h:selectOneRadio layout="pageDirection" id="myRadioButton">
<f:selectItem itemValue="0" itemLabel="Not Specified"/>
<f:selectItem itemValue="1" itemLabel="Person: "/>
</h:selectOneRadio>
</td>
<td valign="bottom">
<h:inputText id="myTextBox" required="true" />
</td>
</tr>
</table>
</f:view>
i have set the table border to 1 to see what is happening.
