  2. Agenda • Who am I • XPages Resources • What are XPages • Why Use XPages • XPages Design Elements • XPages CRUD • XPages Template

  3. Jeff Byrd • Senior Developer at MAXIMUS Inc. • Lotus Notes developer since ver. 3. • Blogger at www.DominoTricks.com • Current series is “Roll Your Own Rest Service”. • Developing xPages for 2 Years. • Twitter @byrd1089

  4. XPages Resources • www.notesin9.com • Created by David Leedy • 27 + hours of FREE videos on XPages • Check out “Introduction to XPages” • Xpages.info • Daily aggregate of XPages blogs • XPages Snippets • OpenNTF.org – Free Source Code • PlanetLotus.org • StackOverflow.com – Filter for XPages • The Rabbit Hole – (nathantfreeman.wordpress.com) • Taming IBM Domino Designer

  5. What are XPages? • New Design Elements and tools for creating web applications • Embraces standard languages • HTML, CSS, JavaScript, Java • Built on top of Java Server Faces (JSF) • XPages is a JSF wrapper for Domino Developers • Everything you code gets placed inside of Java Objects • You never need to deal with those Java Objects though! • You do not NEED to know Java to build XPages apps • But it will help and should be something to strive for • Java in XPages is somewhat similar to LotusScript Custom Classes

  6. Why Use XPages? • Separates UI from Data • Allows multiple Data sources per Page • Easy access to data from other databases • Improves Data capabilities • Allows @DbLookup from inside a view • Similar to a JOIN in relational DB’s. • Use Java Objects (Beans) as data source • Iterate your data anyway you want via “Repeat Control” • Runsinside Notes Client (XPiNC - XPages in Notes Client) • Replicate your web applications.

  7. New Design Elements • XPage • Similar to Notes Form • But not really as you can have none or multiple datasources • Data source can be: • NotesDocuments, NotesViews,Java Beans, and more... • It’s often used more as a container to hold custom controls • Custom Control • Similar to Subform • But not really as you can have none or multiple datasources • Just like XPages • Can be used more then once on a page • Can accept Parameters that you define later • Allows high reusability • Can not be viewed in the browser. They only work on an XPage • Often Custom Controls are used to contain the graphical layout of your app

  8. More New Design Elements • Sever Side JavaScript • Can be on the page or in a library. • Library allows you to create reusable SSJS functions using • It’s not really “JavaScript” but it has the same syntax • This allows additional capability • @Formulas • Domino Object Model • Java Objects • Themes • You can assign a CCS file and it’ll be available on every page of your app • Like a Global “Use” statement in LotusScript • Allow consistent look and feel across apps • oneUI and WebStandard are built in • You can create your own • But always extend a server theme as they contain needed Dojo files • Themes can override controls as well • More advanced but very powerful

  9. Scoped Variables • Scoped Variables • In memory objects to store data • No need to rely on cookies / URL parsing • but you still can if you want • applicationScope • Like a database profile document • Available to all users • Store Application settings and common lookups that all users need • sessionScope • Life of the user session • Store things specific to the user. • Preferences, shopping cart, etc...

  10. Scoped Variables • viewScope • Life of the current Page • Store value of a current search, or items from a particular document • requestScope • Life of a single request • Very short - just for data you’re currently processing • Do NOT try and put Domino Objects (document, view, etc...) in Scope • They will likely get recycled when you least expect it. • For a document, just store a UNID as a string and grab the document again

  11. Building an Application • I’m using Domino and Designer 8.5.3 • Latest version is 9.0 • Do not try Xpages development with any version below version 8.5.1 and you should be using the Update Pack or OpenNTF Extension Library • Update Pack is available from IBM for 8.5. • Ext. Library is at http://extlib.openntf.org/ • What is the Update Pack / Extension Library? • They are add-ons to the Domino Server / Designer • Adds over 50 new tools and controls designed to speed up your application • Tools for layout, Dojo integration, etc. • Application layout control. • Extends the core product without having to wait for next version

  12. Sample Application • Let’s build a quick Contacts Application • One Form – Contact • One View – Contacts • Custom Control – frmContact • Custom Control – vwContacts • xPage – Contact.xsp • xPage – Contacts.xsp • Theme – Blueprint CSS

  13. But there’s more!Things we haven’t talked about • Server Side Java Script (SSJS) • Client Side Java Script (CSJS) • Repeat Controls • Managed Beans • Java!
