HTTP Status Codes

<p>
	By default, a 200 (OK) status is automatically set as the HTTP status when a Java method executes 
	successfully.
</p>
<p>
	Other status codes can be generated by throwing a {@link oajr.RestException} with a 
	specific HTTP status code, or calling {@link javax.servlet.http.HttpServletResponse#setStatus(int)}.
</p>
<p>
	Non-OK (200) status codes are automatically triggered by the following conditions:
</p>
