Facelets Tips
1) Always use head and Body JSF 
tags
You should never use <head or <body> html tags directly in your facelets file. use :
| html | Java server faces |
|---|---|
| <head></head> | <h:head></h:head> |
|
<body></body> |
<h:body></h:body> |
Java Server faces use the jsf tags to find the correponding regions.
Several components are using those tags :
- <f:ajax> use the head tag to insert the javascripts and will not be able to place the file if the tags are missing
- <h:outputStyleshee> need the head to create the css links
- <h:outputScript> need to create script reference in the head region
2) Don't hardcode urls to internal resources
To prevent link error it is a good practive to use relative url or use #{request.contextPath} expression to reference resources
