In This Session …
 The 8.5 release of Lotus Domino and Lotus Domino Designer
revolutionize Domino Web application development

 We’ll introduce you to our new approach for building Web
applications

 We’ll cover some advanced techniques that allow you to leverage
the true power of 8.5

 Finally, we will give you a glimpse of the future

What We’ll Cover …
 Introduction

 XPages — the basics

 XPages — advanced topics

 A glimpse at the future

 Wrap-up

Domino Applications
 Domino is a rapid application development platform for writing
collaborative applications
 Flexible document-based datastore
• Semi-structured data
• Manages hierarchies of documents
• Seamlessly handles data model changes
 Easy deployment model
• Simple NSF copy or replication operation
• Create new instances based on application templates
• Update design provided through design task or replication

 Client access options: Notes, Web browser, or Mobile

* 4


Serving Up Applications to the Web
• Yes, we made it easy to provide browser-based access to your
applications, but they often looked like this:

* 5


Web Development — A Mixed Blessing
 Developer experience
 Programming model delivers maximum capability when building for Notes
 Building compelling Web applications proved challenging
• Domino HTTP rendering issues
• No modern Web controls
• Event model was less than ideal

 So, if you were up for the challenge, you could build compelling
Web applications

 But there has got to be a better way!

* 6


8.5 Application Development Themes
 Provide developers with a modern development tool IDE
 Do for developers what Notes 8 did for end users
• Improve usability and productivity
• Address various developer pain points from previous versions
 Attract new developers to the platform

 Make building compelling Web applications easy
 Allow developers to build attractive, modern Web apps that leverage Web
2.0 technologies with less work
 Provide means to update existing Domino Web applications incrementally

* 7


The 8.5 Answer
 Domino Designer and Eclipse
 Same Designer Productivity: Built on Eclipse
• Eclipse adds: search, editors (CSS, JavaScript, … ), …
 Uses a well-known extension mechanism
• Allows third-party tools to be added

 A new set of design elements
 XPages and Custom Controls
• Designed for developing Web 2.0 applications
• Easy to understand for both Domino and non-Domino developers
 Themes
• Easily define an application’s look and feel

Full support for CSS classes or inline styles
Uses CSS file resources

• Support Themes for skinning an application
Predefined styles for controls

• Extended data access capability
 Applications can access data located in multiple NSF databases
 Multiple documents/views can be displayed on the same page

• Built-in localization and internationalization support
 Support String localization and dedicated pages per locale
 Automatic support for user time zone

* 18


Architecture

* 19


XPage Prerequisites
 Installation and configuration
 XPage runtime is installed by default
 If doing custom install, make
sure Dojo and XPages are checked
 HTTP task must be running

 Skills
 Knowledge of Domino object model
 HTML, CSS, XML, and JavaScript are very beneficial, but you can built an
application without them
 Question = Do I need to learn Java?
 Answer = NO!

* 20


XPage Security
 XPages use agent security model

 Settings for Xpage application access
 XPage signer must have explicit
access to server or select users
listed in all trusted directories
 Other settings that likely
require XPage design element
signature to be added

 XPage Web user access
 Standard Domino Web authentication applies

About the Future
 This is not a commitment on the new features being developed

 This is provided as information to keep you updated and get your
feedback

* 31


Lotus Mashup Integration — iWidget
 A new Component design element is used to define iWidgets
 Any XPage can be projected as an iWidget, leveraging the platform
capabilities (parameters, properties/events, … )

Note: Information is subject to change without notice at IBM’s discretion
* 32


Rich Client Support
• Allows XPages applications to run within the Notes client
 Any XPages application can be run offline
 Do not require a local Domino Server
 Data and Design elements get replicated
• Same code runs identically on the client and the server
 Same programming model on both platforms
• Not restricted to the common denominator
 Takes advantage of the platforms when it makes sense
• Ex: The view control can either render HTML or the Java counterpart
control, depending on the context
• A new theme ensures the consistency with the other Rich Client
applications

* 33


Running XPages in Notes
• Can be used in place of an existing design element
 An XPage can be specified as the launch option

• As a component, within a Composite Application
 Same Component definition used for the iWidgets
 Get access to the platform events (Eclipse selection events, … )

* 34


Mobile Device Support

be presented in a single UI

• Leverage simple actions and JavaScript for business logic

• Use Ajax to improve your end-user experience

• Themes provide a way to easily change the look and feel of your
application

• The revolution starts with 8.5, and the future looks bright
