Create an e4 application with a full-blown project structure

When developing OSGi applications, one question will inevitably come up: how do I structure my OSGi bundles? This tutorial guides you through the steps required to create a JavaFX e4 application with a pre-defined bundle structure that aims for decoupling and minimal dependencies. For details about this structure, see ​Tom's blog post.


  1. Setup a target platform for your application development:
    1. Open Preferences > Plugin-in Development > Target Platform
    2. Click Add ...
    3. Select "Nothing: Start with an empty target definition".
    4. Add ...
    5. Select Software Site
    6. Add ​http://download.eclipse.org/efxclipse/runtime-nightly/site or http://download.eclipse.org/efxclipse/runtime-released/2.0.0/site as a site.
    7. Expand "FX Target" and check "Target Platform for Eclipse" and uncheck "Include required software"
    8. Finish and activate the new target.

  2. Run the New > Project ... JavaFX/OSGi/e4 Application projects wizard.

  3. On the first wizard page, enter a prefix for your application and leave the rest of the settings on their defaults.

  4. On the 2nd page enter a product name and leave the rest as is so the wizard generates tycho build fragments, jemmy-junit tests and other bundles
    Remark: The jemmy-junit option is only enabled if you added JUnit-Testing features from http://downloads.efxclipse.bestsolution.at/p2-repos/addons/nightly/site/ to your target platform

  5. The wizard creates six bundles: the main bundle, a feature bundle, a product bundle, a JemmyFX test bundle and Jemmy feature, and a releng bundle.

  6. Fill your application with life by configuring the Application.e4xmi and adding your source code.
  7. Start your application by open the context menu on $appname.app.product.launch
