These are my slides I used during the webinar hosted by TLCC & Teamstudio on April 21, 2015.
It's the session I held at Engage.UG March 31, 2015 and at ICS.UG March 26, 2015
2. Agenda
•About me
•Overview
•Preamble
•Migrate database and user profiles
• Legacy profile documents vs. Java Beans
• Value lists made available over the whole application
•User and environment information
• What can a user see and use?
•Extending Fulltext search to a facetted search
• Filtering your data with meta tags
3. Oliver Busse
• „Bleeding Yellow“ since 2000
• Working for We4IT Group
• OpenNTF Board Member
• IBM Champion for ICS in 2015

4. Overview
•What‘s this?
• Transforming & re-using commonly used legacy patterns in
XPages
• Don‘t fear Java
• Avoid @Formulas in SSJS
• Ideas for best practices
•What‘s it not?
• An XPages Introduction
• A Java beginner‘s guide
• A complete application migration strategy
5. Preamble
•Why not to use SSJS „excessively“?
• SSJS is interpreted at runtime
• SSJS is compiled at runtime (every time you call it!)
• Compiled SSJS is hard to debug while executed
7. What we find in legacy apps: profile documents
Disadvantages
• You cannot see them without
using tools
• You can edit and create them
only programmatically
• Sometimes replication issues
• Unwanted Caching ;-)
Advantages
• Quick access without using
lookup views
• Caching
8. What we missed in many cases
DatabaseScript != Global Declarations
Encapsuled, no access from outside
(except Database Events)
11. Ingredients
•Transformation of profile documents to „standard“
documents
1. Create a corresponding lookup view
2. Optional: corresponding forms for maintenance
3. Create the Java Bean classes
4. Define those Bean classes in faces-config.xml
12. Preparation: Lookup Views
•Key for Database Profiles = dbprofile
•Key for User Profiles = Canonical User Name
•Key for Value Lists = free but unique
13. Preparation: Java Beans
• 3 Classes:
• DatabaseProfileBean
• AppConfigBean
• UserProfileBean
• The DatabaseProfileBean initializes the document if
it doesn‘t exist
• The UserProfileBean initializes the document when
the user saves it for the first time
15. Digression: Bean Scopes & Lifecycles
•Request
• Lives beginning with the request to creation of the response
•View
• Within a page until changing the page, even during partial
refreshes
•Session
• Per user session
•Application
• During the life time of th application (after 30 minutes it is
dropped by default)
25. Facetted Search
„Faceted search, also called faceted navigation or faceted browsing,
is a technique for accessing information organized according to a
faceted classification system, allowing users to explore a collection of
information by applying multiple filters.“
http://en.wikipedia.org/wiki/Faceted_search
28. Facetted Search with Domino?
1. Fulltext Search
2. Filtering result from extra meta data
1. Meta data search with facet selection
2. Fulltext Search in results
31. Facetted Search: Outlook & Alternatives
•Using OpenNTF API‘s Graph-DB functions
•Using a 3rd party Graph-DB like Apache Solr

32. Want to get the DEMO?
Grab it from my Bitbucket repo (also contains an NTF):
https://bitbucket.org/zeromancer1972/icsug-2015-demo
It uses the following plugins available on OpenNTF:
XPages Extension Library (9.0.1.07+):
http://extlib.openntf.org/
Bootstrap 4 Xpages:
