API Tooling

  • generate a snapshot for a particular set of source code (JARs or bundles)
  • compare another source set with snapshot and get 3 summary pages
    • breaking changes
    • non-breaking changes
    • version number checks

Application Model

The Eclipse platform implements an application container that is based on the OSGi Application Admin Service specification. This demo shows how Eclipse applications can be managed using the OSGi Application Admin Service specification

The Projects

The projects for the demo are stored in the Equinox Incubator on the main Eclispe CVS repository (dev.eclipse.org:/cvsroot/eclipse). All projects are under the directory equinox-incubator/demos/app-model/.

org.eclipse.equinox.examples.app.selector

This project provides a simple RCP application that uses the application admin service to manage the other applications installed on the platform.

org.eclipse.equinox.examples.sharedisplay

This project provides a simple headless application that sets up a shared display that other applications can share when they are launched.

example SWT applications

Each of the following projects provide an example SWT application that can be launched using the application admin service

  • org.eclipse.swt.examples.addressbook
  • org.eclipse.swt.examples.browserexample
  • org.eclipse.swt.examples.clipboard
  • org.eclipse.swt.examples.graphics
  • org.eclipse.swt.examples.paint

How to Run

There are two ways to run the demo.

  1. Using the application selector UI
  2. Using the headless share display application

Using the application selector

This approach launches an RCP application called application selector. This application is provided by the org.eclipse.equinox.examples.app.selector project. Since this approach uses an RCP application many other bundles are required to run. For example, the org.eclipse.ui.workbench and all of its dependencies. The application selector displays the following information about each SWT example application installed on the platform:

  1. The application name
  2. If the application is enabled.
  3. The application state (inactive, starting, running, stopping)

To start the application selector use the Eclipse Application launcher called demoAppSelector. This launcher is included in the org.eclipse.equinox.examples.app.selector project.

Start an Application

Select an application to start from the application selector then use the context menu to run the start operation. Note that the start operation will be disabled if the application state is not currently inactive This will cause the application to launch. You should notice the state of the application move to running and the application will become disabled. Disabled indicates that the application is no longer available for launch. This is because all applications in this demo have a cardinality of 1. Try launching other applications at the same time. You will be able to launch all applications that are enabled at the same time.

Stop an Application

Select an application to stop from the application selector then use the context menu to run the stop operation. Note that the stop operation will be disabled if the application is state is currently inactive. This will cause the application to stop. You should notice the state of the application move to inactive.

Stop the Application Selector

If the application selector is stopped while one or more of the example SWT applications are running then it will stop all of them before exiting the application selector.

Using the headless application

This approach launches a headless application which sets up a shared display for the example SWT applications to use. This application is provided by the org.eclipse.equinox.examples.sharedisplay project. This approach does not use an RCP application which allows it to run with a minumum set of bundles. Since there is no UI available to control applications we must use the osgi> console commands provided by the org.eclipse.equinox.app bundle to start and stop the applications.

To start the application selector use the OSGi Framework launcher called equinoxShareDisplay. This launcher is included in the org.eclipse.equinox.examples.sharedisplay project.

Start an Application

To see a list of applications run the apps console command

osgi> apps
org.eclipse.swt.examples.paint.app [enabled]
org.eclipse.swt.examples.graphics.app [enabled]
org.eclipse.swt.examples.addressbook.app [enabled]
org.eclipse.equinox.examples.sharedisplay.application [disabled]
org.eclipse.equinox.app.error [disabled]
org.eclipse.swt.examples.browserexample.app [enabled]
org.eclipse.swt.examples.clipboard.app [enabled]

Pick an application id to start and run the startApp command. This will cause the application to launch.

osgi> startApp org.eclipse.swt.examples.paint.app
Launched application: org.eclipse.swt.examples.paint.app

You should notice the application becomes disabled. Disabled indicates that the application is no longer available for launch. This is because all applications in this demo have a cardinality of 1.

osgi> apps
org.eclipse.swt.examples.paint.app [disabled]
org.eclipse.swt.examples.graphics.app [enabled]
org.eclipse.swt.examples.addressbook.app [enabled]
org.eclipse.equinox.examples.sharedisplay.application [disabled]
org.eclipse.equinox.app.error [disabled]
org.eclipse.swt.examples.browserexample.app [enabled]
org.eclipse.swt.examples.clipboard.app [enabled]

Try launching other applications at the same time. You will be able to launch all applications that are enabled at the same time.

Stop an Application

Select an application to stop from the application selector then use the context menu to run the stop operation. Note that the stop operation will be disabled if the application is state is currently inactive. This will cause the application to stop. You should notice the state of the application move to inactive.

Stop the Application Selector

If the application selector is stopped while one or more of the example SWT applications are running then it will stop all of them before exiting the application selector.

How it Works

Launcher Demos

Demos related to the new launcher work.

Phone Demos

Provisioning Demos

Demos related to the new provisioning story can be found here.

Resource Monitoring Demos

Check out the Equinox Incubator for more information on our Resource Monitoring demos.

Server-Side OSGi

  • JSPs - there are some demos that come with Tomcat and Struts
  • Embedded in app server
  • show the dev scenario - easy to use
