Agenda
 Why?
 Development Environment & Debugging
 Repository Structure / Deployment
 Basic Plugin Structure
 Providing Client-Side Resources
 Providing Third-Party Java Classes
 Providing Components
 Summary

XPages Developers
 11 types of developer - Stephan Wissel
 Three types of developer - Niklas Heidloff
 Five tiers of developers - Greg Reeder, in "A Few Years of XPage Development" series
Extension Library development should be
the goal of XPages developers

Why?
 Build Once, Use Anywhere (virtually!)
 Easier to deploy new versions and exploit replication
 Deploy third-party libraries
– Apache POI etc
– JDBC Drivers
 Deploy client-side code server-wide
 More easily avoid Java security exceptions
– Security tightened in Domino 9
 Required for DOTS (Domino OSGi Tasklet Service) or XPiNC XSP.executeCommand

Examples Plugins
 XPages Extension Library
 IBM SBT
 XPages OpenLog Logger
 OpenNTF Domino API
 Bootstrap4XPages
 XPage Debug Toolbar
 XPages Scaffolding
 XPages Toolkit
 POI4XPages

JDBC Driver Plugin Wizard
 Enhancement to RDBMS part of Ext Lib
– Designer Client only functionality
 Requires latest version of ExtLib
 Allows a plugin to be created from one dialog
for a JDBC driver
 See 3:15 on video

DEVELOPMENT
ENVIRONMENT &
DEBUGGING

Configuring the Environment
 Eclipse
 XPages SDK
 Local Domino Server recommended
 See Installation video from Niklas Heidloff
– Dates from before Debug Plugin was incorporated into XPages SDK
– Dates from before Extension Library was Maven-ized
• See http://www.openntf.org/main.nsf/blog.xsp?permaLink=PWIS-9QZTH2 for that
 See blog series from Paul Withers

Eclipse for RCP and RAP Developers
 Latest release is Luna
– Latest release of XPages SDK fixed to support this release
 Can have multiple versions installed
 Load multiple instances

XPages SDK
 Gives XPages JREs and Target Platforms
– JRE → which plugins and jar files are automatically available
– Target Platform → which application / OS plugins are built for
 From 4:40 in video
 Point Preferences to Domino and Notes installs
 Ensure “Automatically create JRE” ticked
 Tick relevant entry in Java > Installed JREs
 Create and select entry under Plug-in Development > Target Platform

Debugging
 Debug Plugin now part of XPages SDK install
 Allows you to point Domino server direct to projects in relevant workspace
 From 14:10 in video
 Point Preferences to Domino install
 Configure Domino server for Java debugging, as for Java development
 Run > Debug Configurations
– Create Debug Configuration
 Connect as with Domino
– Use Step filters to skip certain packages

OSGi Configuration
 Allows Domino Server to use plugins directly from Eclipse workspace
– Direct access to source code (.java files), not compiled code (.class files)
– Speeds up development / debugging
 Create new OSGi Framework configuration
– Set as Domino OSGi Framework
– Set auto-start to false
– Click Debug – creates pde.launch.ini
– Issue “res task http” command
– Obviously will cause problems on networked server!

When Plugins Are Created / Imported / Amended
 For added / imported plugins
– Go to OSGi Framework configuration
– Select the new plugin
– Click Debug to update config
 If plugin is changed

REPOSITORY
STRUCTURE /
DEPLOYMENT

Structure
 Project inter-relations will differ for Mavenized plugins
– Maven is XML structure for automatically importing dependencies and building multiple plugins
– Managed by a “parent” project, see Ext Lib demos or Christian’s blog series
– Maven has its own learning curve, so we’ll skip that for now
 Plugin project
– This is all that's needed for OSGi framework configuration
 Feature project loads one or more plugin
 Update Site project points to one or more feature
– Creates plugins and features jars
– Export as General > File System

Deployment to Server / DDE
 Server:
– Run from Eclipse using Domino Debug Plugin
– Install to remote server as other Ext Libs
• See Chapter 2 of XPages Extension Library pp28+
 Client
– Install to DDE as other Ext Libs
• Every change you make to the component re-install the update
• Quite laborious for development, but know when you need to re-import and when you don’t!
– Add directly to DDE plugins
• Best to create separate directory. See blog post by John Cooper or slides at end

Troubleshooting
 Server
– “tell http osgi diag com.myplugin.name” console command confirms any missing
dependencies
 Client
– check Help > Support > View Log and View Trace for errors / print statements

Deployment to Development Team / XPiNC
 Add to Widget Catalog from Update Site database
– See XPages Extension Library pp40+
 Best practice is using Desktop Policy, ensures updates automatically deployed

Plugin Structure
 See Extensibility API Developers Guide
 Activator is optional
– Allows generic code to be run
 Extend org.eclipse.core.runtime.Plugin

Extensions Tab
 Extensions load other Java classes
 Use extension point
com.ibm.commons.Extension
 Use “tell http osgi pt -v com.ibm.
commons.Extension” to see types
and classes currently loaded

Library Class
 This is what is selected in Xsp Properties
 Type: com.ibm.xsp.Library
 Class: your.package.Library extends AbstractXspLibrary
 Defines
– Dependencies
– Faces-Config files
– Xsp-Config files

Contributor Class
 This adds factories
– Holds server-level maps
– Load implicit objects (variables)
 Type: com.ibm.xsp.library.Contributor
 Class your.package.Contributor extends XspContributor

From XSP Starter Kit to Clean Plugin

PROVIDING CLIENT-
SIDE RESOURCES
Angular 4 ALL

Angular for all!
 Angular.JS is popular java script framework to build client-side applications.
 XPages Developers typically distribute Angular to their application by adding the script
library to the WebContent folder
 But let me show how easy it is to deploy angular as part of a plugin and imagine how easy
it would be to deploy your java script standard components

Making your plugin to a resource provider
 Time to contribute to an extension
– com.ibm.commons.Extension
• Type: com.ibm.xsp.GlobalResourceProvider
• Class: your.package.ResourcesProvider ->
extends BundleResourceProvider
 Add some folders to the plugin
– resources/web/angular
– put angular.1.3.8.min.js, angular.1.2.28.min.js and
angular-1.1.4.min.js in the folder

Lets write some code to make the files available as
.ibmxspres/.angular/xxx.js
 The following code let the resource provider understand where he can find the .js files:

Lets write some code to make the files available as
.ibmxspres/.angular/xxx.js

Don’t forget to export the resources during the build
 You won’t believe how many times I was struggling at this point.
– Open the Manifest.MF and go to the tab build

All done? How can a developer now consume this java script libs?
 He knows the following url statement /.ibmxspres/.angular/angular.1.3.8.min.js  UGLY
 We can build a custom theme and provide this
theme (like the Bootstrap4XPages Project does)
 We build a component and gives the user choice.

The component (A java representation of an XPages Element)
 The following Code represents the component (Paul will later explain more about)

Angular.xsp-config (make the component visible in the DDE)
 Here the .xsp-config file to make the component visible in the DDE (Paul will also explain
this later ;) )

The renderer (This piece of code brings the angular.js on your page)
 (Yes Paul will also explain this!)

Angular-faces-config.xml -> Instruction for the renderer

Demo and Summary
 Imagine that you can in the same way multiply the usage of your brilliant java script code
or the CSS style sheet for your cooperate design
 Imagine that you can also customize the look and feel of all Application-Layout based
XPages Apps by defining a plugin with some resources and an new Theme
 Imagine how productive your development team can become because you have make
your work easy consumable

Plugin for Third Party Jars
 Create a separate plugin
– New > Plug-in from Existing JAR Archives
• Add .qualifier to version
• Always adds a new version to plugin folder of Update Site
– For additional jars
• Import the jar
• Add to Build Path
• Ensure included in Binary Build on build.properties
– Also blog post by John Dalsgaard

Including Plugin
 Add as Required Plug-in to plugin.xml
 Click on Properties and tick “Reexport this dependency”
 Add to feature
 Ensure “Unpack the plug-in archive after the installation” is ticked
– Otherwise DDE will not see the jars

Creating Component Plugin
 Take a custom control and make it global
 NotesIn9 64 by Tim Tripcony #codefortim
 Or code within Eclipse
 Extensibility API 9.0.1

Classes for Component
 Component class DOMINO / DDE (Setters / Adders only)
 .xsp-config to add properties DDE
– See http://avatar.red-pill.mobi/tim/blog.nsf/d6plinks/TTRY-8DDDEZ for making Eclipse identify
*.xsp-config files as XML files #codefortim
 Renderer class, if required DOMINO
– Use getRendererType() to find an existing renderer
 faces-config.xml to register renderer with server DOMINO
 Load xsp-config and faces-config.xml in Library class

Demo Plugin
 Add component for Separator
 Allow properties for:
– separatorType (New Line / Space)
– count (integer, defaulting to 1)
 Deploy org.apache.commons.lang3
 Add utility method to convert any object to string detailing properties

Configuring DDE for Adding Plugin Directly
 Navigate to framework directory inside the Notes Data Directory
 Create a new plugin directory
 Create a .link file
 Inside your newly created text file add the following:
 path=C:/Program Files (x86)/IBM/Notes/framework/pluginsExt
 Update platform.xml
 Change the transient attribute on the config tag to false
 Replace all the instances of policy="MANAGED-ONLY" to policy="USER-EXCLUDE"

Exporting Plugins Directly to DDE
 Export plugin as a “Deployable Plugin and Fragment”
 Put in newly created directory
 Restart designer
