Domino API and CrossWorlds

2. UKLUG 2012 – Cardiff, Wales
Quiet Year?
• No release?
• RC2, RC3 (M5 and M5.1)
• Further struggles with Maven / Tycho
• Not designed for plugin development
• Imminent release – ODA 2.0.0

3. UKLUG 2012 – Cardiff, Wales
Xots Update
• Further development, proven in production
• Blog posts http://www.intec.co.uk/tag/xots/
• Implement Callable to interact with return
value
• Implement Runnable to just run
• @Tasklet annotation required

4. UKLUG 2012 – Cardiff, Wales
Xots – How To
Xots.getService().submit(new
myRunnable(ExtLibUtil.getSessionScope());
• invokeAll() not currently working
• Pass “shared” variables into constructor
• Stored in private variables of Xots class
• By default 10 threads at once

5. UKLUG 2012 – Cardiff, Wales
Xots – How To
List<Future<String>> results = new
ArrayList<Future<String>>();
….
results.add(Xots.getService().submit(new
myCallable());
….
for (Future<String> f : results) ….

6. UKLUG 2012 – Cardiff, Wales
Xots – How To
@Tasklet(session = Tasklet.Session.CLONE)
• Denotes that this class is a tasklet
• Denotes that it should clone current session
Extended to CrossWorlds, coming soon to
OsgiWorlds

7. UKLUG 2012 – Cardiff, Wales
Scheduled Xots?
• Still pending
• The challenge:
• How many Domino developers have
experience of building a stable process
scheduler?
• Scheduling issues with DOTS

Single, re-sortable container, containing 13376
contacts from 10 databases

Session Management
• Previously
• ExtLibUtil.resolveVariable(“session”)
• Factory.getSession()

11. UKLUG 2012 – Cardiff, Wales
Session Management
• Now
• ExtLibUtil.resolveVariable(“session”)
• Factory.getSession
(SessionType.CURRENT)
• SessionType enum
• Because more than just three XPages
sessions

Graph Update
GRAPH
Elements
Key / value pairs
Index free
DOMINO
Documents
Item / value pairs
Indexing issues

13. UKLUG 2012 – Cardiff, Wales
Graph Update
• Framed Graphs
• Simplified setup
• In-built Vertexes
• Likeable, Commentable, workflow
• Proxy Vertexes
• Wrappers for non-Graph Notes
documents

DasServlet
• org.openntf.domino.rest.servlet.
ODADataServlet
• Extension to DAS, allows use of ODA
• Use for custom REST servlets
• Recommended for e.g. AngularJS apps
• Wraps currently-logged-on user’s session
in ODA session
• ContextInfo.getUserSession()

16. UKLUG 2012 – Cardiff, Wales
JS Frameworks
• Which one
• Plus you still need
a REST
“application”

17. UKLUG 2012 – Cardiff, Wales
OsgiWorlds
• Osgi applications within application path
force authentication based on NSF
• http://myServer/names.nsf/myOsgiApp
requires authentication if names.nsf does
• If authenticated, can use ContextInfo for
current Domino authentication
• OsgiWorlds uses OSGi application-level
authentication (same as CrossWorlds)

18. UKLUG 2012 – Cardiff, Wales
OsgiWorlds
• VaadinServlet
• Filters all servlet requests
• Application configuration to “map” to
Domino sessions

19. UKLUG 2012 – Cardiff, Wales
CrossWorlds
• WebSphere Liberty (8.5.5.4) +
• IBM Domino (9.0.1) +
• OpenNTF Domino API +
• CrossWorlds feature for Liberty
• Application-specific authentication with
Domino security

20. UKLUG 2012 – Cardiff, Wales
Websphere Liberty Profile
A fast J2EE Application Server built by IBM
for modern needs.
- Light (< 40 Mb ram, < 5sec startup)
- Open (OSGI based + J2EE 6 / 7)
- Constantly evolving
- Extensible (customizable to the limit)
- Easy to manage (unzip & run, no install
needed)

21. UKLUG 2012 – Cardiff, Wales
Java 1.7 / 1.8
• Domino JVM is 1.6, 1.8 coming
• WAS Liberty can run on 1.6/1.7/1.8
TODAY!
• You can build your reusable frameworks or
exploit existing frameworks for your apps.
• Not tied anymore to IBM’s choices for
Domino

22. UKLUG 2012 – Cardiff, Wales
New Demo Application
• Not built on XPages
• Vaadin on Websphere Liberty Profile /
Domino OSGi
• ODA is no longer just XPages
• XPages developers more comfortable
with Java / less interested in ODA
• Domino (ExtLib demo) datastore

23. UKLUG 2012 – Cardiff, Wales
Vaadin
• Java framework for web / mobile apps

24. UKLUG 2012 – Cardiff, Wales
The Obvious Java Choice
• Code WYSIWYG, XML markup or Java
• 400+ components
• Client-side development tools based on
GWT and HTML5
• Open source
• Webinars, training, certifications, support
• Pro tools, including charts, touch kit etc
• First third party boilerplate inside Bluemix

What Does ODA Mean?
• ODA means:
• Keep data on Domino
• Develop with more than just standard
Domino architectures
• Develop with more than just XPages
• Develop web app beyond Domino
• Bluemix??
