7. XPages
§ XPages is a great technology and expands our possibilities – from
the point of administrators, developers and users.
§ Starting with XPages could be really simple. For the very first steps
is just drag‘n‘drop, computing stuff and so on.
§ To be honest: Domino web development never was so easy (after
you‘ve learned the basics) - even if it takes „slightly“ more time.
7

8. XPages
§ The most powerful component is the editable area.
8

9. XPages / XPages Extension Library
§ There are some things which aren‘t so easy...
§ You are missing controls in the pallette
§ OneUI ist too complex
§ You want some custom rendering
§ ...
§ Here the XPages Extension Library comes to your help.

10. XPages Extension Library
10

11. XPages Extension Library
§ IBM has introduced the XPages Extensibility API with Notes/Domino
8.5.2.
§ This API is a set of Java classes and methods which allow to
integrate specialised functionality directly into XPages.
§ This means XPages in the browser and XPages in the Notes client.
§ IBM has used this API to provide the well-known XPages Extension
Library – (first) on OpenNTF and than as part of the core product!

13. XPages Extension Library
§ You‘ll finde it on OpenNTF http://extlib.openntf.org
13

14. XPages Extension Library
§ It‘s part of Notes/Domino 8.5.3 as „Upgrade Pack 1“ – full product
support through IBM!
§ Part number: CI5GIEN
§ Watch out: If you want to use the Upgrade Pack 1 you‘ll have to
uninstall previous versions of the OpenNTF Extension Library.
§ IBM installs the UP1 in the program directory. The OpenNTF
components are installed in the data directory.
§ Currently only available as Installer – not as Updatesite.

15. XPages Extensibility API
15

16. XPages Extensibility API
§ It only makes sense to develop your own extensions if you need the
same functionality across multiple applications.
§ An extension (aka OSGi Plug-In) needs only to deployed once per
server or client – not per application.
http://www.osgi.org <= start here
16

17. XPages Extensibility API
§ So called „artefacts“ can be added to the existing API during
runtime.
§ JSF is an „open standard“ which APIs are publically available.
§ The XPages APIs are public since Domino 8.5.2.
§ Artefacts can be:
§ UI Controls
§ Converters
§ Validators
§ Data Sources
§ Simple Actions
§ Language Bindings
§ ...
17

18. XPages Architektur
18

19. XPages API Concepts
§ XPages Library
§ OSGi bundle, contains Java code, configuration files
§ Controls
§ Components which are available in the Designer pallette
§ Renderer
§ Renderer are responsible for displaying the output (HTML, CSS, ...)
§ Complex Types
§ Those are i. e. used to create encapsulated functions or store data.

§ For keeping it simple: use the OpenNTF project „XPages SDK for
Eclipse RCP.

79. Deployment Domino-Server
§ Create a new database/application based on the Updatesite
template. I highly recommend to use a dedicated database for
server-only plug-ins in a production environment.
§ Import the plug-ins into the database.
§ Replicate the database with all according servers.
§ Plug-Ins couldn‘t be replicated as they „normally“ reside on the file
system.
§ Set the notes.ini parameter
OSGI_HTTP_DYNAMIC_BUNDLES=<database.nsf> on the Domino
servers.
§ Finished. Restart the http and that‘s all.
