> I found a way to reduce JSF based application to start faster on GAE.
> 1. Register all managed beans statically in faces-config.xml 
> 2. Use metadata-complete="true" attribute, so faces-config.xml boilerplate is:
> <?xml version='1.0' encoding='UTF-8'?>
> <faces-config xmlns="http://java.sun.com/xml/ns/javaee"
>               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>               xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
>               http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
>               version="2.0"
>               metadata-complete="true">
>     
> <!--Your stuff here-->
> </faces-config>
> Using this technique you force JSF not to scan classes for beans. You can leave bean annotations in source code for user's clarity. It will not produce any error.
> 3. Force JSF not to check xml syntax. I hope IDE do it instead. In web.xml set context parameter as here:
> <context-param>
>      <description>
>          Set this flag to true if you want the JavaServer Faces
>          Reference Implementation to validate the XML in your
>          faces-config.xml resources against the DTD. Default
>          value is false.
>      </description>
>      <param-name>com.sun.faces.validateXml</param-name>
>      <param-value>false</param-value>
> </context-param> 
> Using these tricks I reduce GAE start time by two seconds. Not bad.
