Agenda Types of Plugins What‘s All The Parts Needed ? Setup The Development Environment Run / Debug Configuration Build a simple Menue extension Build a Sidebar Plug-In Working with existing code Extension Points Deploy Plug-Ins Plug-In Security

It‘s only one way of doing it …
And I know there's a few to demonstrate the theory

No animals were harmed * during the making of this presentation !
* That part comes, when you download the slides from http://slideshare.net

Types of Plug-Ins Adding new items to a menue bar or a context menue Display data in the Sidebar

Build Your First Plugin

Create A Simple Menue Plugin Add a new menue Add a new menue entry Display a message

Create A New Plug-In Project Alt + Shift + n

Plug-In Basic Configuration Give your Plug-In a name Set the Provider Check „Generate an activator …“

Create From Template Select a template

Your Workspace Should Look Like This

Anatomy of a plugin The plugin.xml contains meta- information for Eclipse, and contains the extension points declared/used by this plug-in The MANIFEST.MF is a standard Jar manifest, but contains meta- information used by Equinox, which is Eclipse's internal OSGi engine. Although there are specific entries in here for Eclipse (such as Eclipse- LazyStart ) the majority of entries here are standard OSGi

Anatomy of a plugin The Activator is run when your plugin starts, and before any other code that's defined in your bundle is used. You can use this to initialise data structures, start listening to network sockets etc. It's also got a call when Eclipse shuts down Last (but not least), the SampleHandler , which just prints out "Hello, ConnectSCOTT" when you click on the little blue Eclipse icon in the toolbar.

Source Code (SampleHandler.java)

Create A New Run Configuration

Assign Plug-ins to Launch Configuration

Run / Launch Plug-In

Debug Plug-In Code

Create A Sidebar Plug-In

Create a SideBar Plugin Simple Sidebar Plug-In for text snippets Content can be
•loaded from file
•saved to file Content is persistent between sessions

Create A Sidebar Plugin (cont) Create a new Plug-In Project
•File  New  Plug-In Project
•Type in Project Name

Create A Sidebar Plugin (cont) Check „Generate An Activator“ Leave Defaults or set it to a name of your choice. Depaends on how you organize your code Click NEXT to use a wizard, or FINISH to go do the heavy lifting on your own

Create A Sidebar Plugin (cont) Your project will look similar to the screenshot; Extension section is empty

Create A Sidebar Plugin (cont) Add Extension Points

Create A Sidebar Plugin (cont) Add category and view to the „org.eclipse.ui.views“ extension Repeat steps for all other extensions
•com.ibm.rcp.ui.shelfViews

Working With Existing Projects

Working with existing projects

Import into Eclipse Workspace

Plugin imported, but … ERRORS 
1.Go to the Build Path settings in the project properties.
2.Remove the JRE System Library
3.Add it back; Select "Add Library" and select the JRE System Library.

Extension Points

Understanding Extension Points http://www.eclipsezone.com/eclipse/forums/t93753.html?start=0

Extension Point Description Select the extension point in the Extensions section of the manifest and click „Show extension point description“ . This will open a new tab with all the information about the extension point

Plug-In Provisioning

Plug-In Provisioning Prerequisites Before we can install / deploy our plugin, we have to do some additional work
•Create Feature Project
•Create Update Site Project
•Build Update Site content

Create a new feature project An Eclipse feature project contains features. A feature describes a list of plug-ins and other features which can be understood as a logical unit. It also has a name, version number and license information assigned to it. A feature is described via a feature.xml file
File  New  Feature Project

Create a new feature project Give your project a name Change other values to your needs

Create a new feature project Select the plug-in(s) from the list. You can type in the name to easily navigate to the plug-in. Click Finish and Eclipse will create the feature project.

Create a new feature project If you are using Working Sets, you will not see the feature project Edit the current Working Set and add the feature project

Create Update Site Project The Update Site contains feature and plug-in versions for Eclipse project releases.

Create Update Site Project Give your project a name

Create Update Site Project Add feature(s)

Create Update Site Project Build the content

Deploying Plugins Let the user deploy the plugin Deploy during client installation Deploy plugin via Widget Catalog and Desktop Policy

Option 1: Let the user install the plugin

Option 1: Let the user install the plugin „Install“ not enabled by default.
•customize plugin-customization.ini on client
•add com.ibm.notes.branding/enable.update.ui=true Disabled by Desktop Policy

Option 2: Deploy during client installation Customizing Notes install for features and plug-ins on Windows and Mac *
*

Option 2: Deploy during client installation

Option 3: Widget Catalog and Desktop Policy

Create Update Site Database If you do not already have an „Update Site“ Create a new Update Site
•File  Application  new
•Check „Show advanced templates
•Select „Eclipse Update Site“

Import Local UpdateSite into Database

Install In Sidebar Get URL of the plug-in

Install In Sidebar Tools  Widgets  Getting Started with Widgets  Features and Plugins Paste the URL Click „Load“ Check Feature to install Optionally provide an image url

Confirm Installation Select „Install plug-in“; Click „OK“ The plug-in will be installed; Then restart the client

Publish To Catalog
