This document discusses CrossWorlds, which allows developing generic web applications using the IBM Domino application server. CrossWorlds is a feature for IBM Websphere Liberty Profile that makes Liberty act like a Domino server to applications. It allows accessing Domino data and services via the OpenNTF Domino API from standard web applications. CrossWorlds provides advantages like Domino's security and data storage along with Liberty's speed and tooling. The OpenNTF Domino API also provides more flexible session handling and data access than traditional XPages development.

3. Paul Withers
• XPages Developer since 8.5.0
• Founding co-developer on OpenNTF Domino
API
• Early adopter / contributor of CrossWorlds
• Developer of OsgiWorlds

4. The Scope
• Developing with generic web applications
• Vaadin, JAX-RS
• Websphere Liberty Profile (or Domino)
• Storing data in Domino via Java
• Think you know Domino? Think again!
• Entry points via ODA counterparts of Domino
objects

5. Beyond Scope
• Which web framework
• DAS
• Authentication to Domino
• You’ll see why!
• Authentication to the application
• Integration with Connections / SmartCloud

6. Why Not XPages?
• IBM SBT
• Not actively update on OpenNTF
• GitHub XPages-specific code not actively developed

7. But Why Domino?
• Wrong question
• Wrong time

8. What Is CrossWorlds?
• Websphere Liberty Profile 8.5.5.4 +
• IBM Domino 9.0.1 +
• OpenNTF Domino API +
• CrossWorlds feature for Liberty

9. What Is CrossWorlds?
• Liberty server that Domino thinks is a Domino
server!
• Filter wraps all requests in ODA sessions
• Developed by Daniele Vistalli Dec 2014

10. The Right Questions
• Whose session?
• Which user?
• What are advantages of Domino?
• What are advantages of Liberty?
• What are advantages of ODA?
• Can it be done without Liberty?

11. Whose Session?
• User
• Based on authentication
• Via Factory.getSession(SessionType.CURRENT)
• “Signer”
• web.xml context-param
org.openntf.crossworlds.appsignername
• Via Factory.getSession(SessionType.SIGNER)
• Server
• Via Factory.getSession(SessionType.NATIVE)

12. Which User?
• Development mode:
• Defined in web.xml context-param
org.openntf.crossworlds.devtimename
• Production mode:
• Authenticate however you wish
• Generate Domino username however you wish
• Store in xworlds.request.username HttpSession
attribute
• Manage Domino security as normal
• com.ibm.domino.napi.c.xsp.XSPNative.createXPa
geSessionExt()

13. What Are Advantages of Domino?
• Strong security
• Schema-free storage facility
• Replication
• Great at workflow
• Great at handling attachments
• Mail routing
• Often found in Connections customers
• On premise or cloud (SoftLayer)

14. What Are Advantages of Liberty?
• Fast JavaEE application server
• Extensible (hence CrossWorlds)
• Easy to install
• Eclipse tooling
• Exploit Java 1.7 / 1.8 today
• Develop standard web applications
• Scheduled Executors
• Use JRebel for hot-swapping of code

15. What Are Advantages of ODA?
• More flexible session handling
• More flexible field handling
• Automatic recycling of Cpp handles
• OpenLog for error / event logging
• Xots – threaded tasklets
• Transactional processing
• Event Listeners
• Framed graphs

16. What Are Framed Graphs?
• Extends Tinkerpop framework
• Java interfaces for Vertices / Edges
• Can wrap standard Domino documents
• E.g. Person documents
• Inbuilt workflow and social elements
• See

17. Can It Be Done Without Liberty
• Vaadin? Enter OsgiWorlds
• Expeditor Web Container
• Vaadin servlet wrapping intercepting HTTP requests
• Same functionality for session handling
• REST? OdaDataServlet
• Equinox HTTP Service
• Just wraps Domino-authenticated user session
• See http://www.intec.co.uk/xpages-to-web-app-part-
eight-osgi-jax-rs-rest-access-with-oda/
• XPages – of course

18. So Why?
• Flexible authentication options + security
• Flexible storage options – NoSQL or Graph
• Flexible location – SoftLayer or on premises
• Flexible web application options

19. More Information…
• Intro to ODA, ODA 2.0.0, ODA Demo Db (WIP)
• Intro to CrossWorlds, CrossWorlds on GitHub
• OsgiWorlds
• Graph in ODA
• oAuth authentication to Connections with SBT
• Mikkel Heisterberg session on oAuth
