iPhone output channel
Now let’s look at the html-iphone/template.template-web-blue.jsp :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">….<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="${fn:substring(renderContext.request.locale,0,2)}"><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

iPhone output channel (2)<body><div class="bodywrapper"><!--start bodywrapper--> <!-- ACME logo --> <div id="header">
<template:module path="header-col1"/> </div> <!-- Navigation menu -->
<template:module path="headerBottom-colContent"/> <!-- Main content for most templates -->
<template:area path="maincontent"/> <!-- News detail view -->
<template:area path="row-col1/mainResourceDisplay"/> <!-- Event list view -->

Locating content
Contains ACME logo
Contains navigation
Content tree
Using REST API to build native mobile clients
Native Mobile Rendering
Features
• Server-customizable• Native application, good user experience,
fast, and works offline• Flexible architecture
DemoNative Mobile Rendering
Initial connection
Mobile device Jahia Server
retrieve configuration
fetch section data
section data
fetch data template
data template & resources
Fetching new section
Mobile device Jahia Server
fetch section data
section data
Offline operation
•Data is cached locally•Upon reconnection, data is retrieved from
server• If server or connection falls, requests default
back to cache
Templates
• HTML rendering• Merged client side• Template for each
node type• Different template
for different devices
<html><body><h1>$$$jcr:title$$$</h1><a href="$$$file$$$"><img src="$$$preview$$$"/></a><p>$$$date$$$</p>$$$body$$$</body></html>
Rapid Application Development
• All files are reloaded from server when connected
• No changes needed on the client side, only on server side !
• Resources such as images, CSS, Javascript can be changed on-the-fly on the server.
• Per node-type templates, modify rendering one object at a time
Submitting content
• Uses REST POST API• Submits data file first, then uses returned
UUID to create a node with a reference to data file
• Mappings are used to configure content creation location and property names

Q & A
Other HTML alternatives
Create a separate “m.jahia.com” mobile specific site and use content references or queries to retrieve content
Benefits:• Can use Template Studio to design templates• Can add mobile specific content
Disadvantages:• More editorial work to keep both sites in sync• Not as seemless, be careful about navigation
