<HTML><BODY>Hi all,<br><br>I found out that in order to control instance creating in Grizzly it is necessary<br>to override some methods in WebappContext.

<br>
In undertow an extension is a service provider of <br>
io.undertow.servlet.ServletExtension, loaded automatically during <br>
startup (see also java.util.ServiceLoader). You need to find out how and <br>
where Grizzly allows to customize the instantiation/injection of <br>
components.<br>
<br>
