Richfaces-showcase: GAE start time decreasing
---------------------------------------------
Key: RF-10259
URL: https://issues.jboss.org/browse/RF-10259
Project: RichFaces
Issue Type: Enhancement
Security Level: Public (Everyone can see)
Reporter: Ara Minosian
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.
