OSGi and Gravity Service Binder Tutorial

This tutorial creates successively more complex OSGi bundles to illustrate most of the features and functionality offered by the OSGi framework. It culminates by demonstrating how the Gravity Service Binder can be used to greatly simplify creating OSGi applications.

• Example 1: A simple bundle that listens for OSGi service events.
• Example 2: A bundle that implements a dictionary service.
• Example 2b: A bundle that implements another variant of the dictionary service.
• Example 3: A bundle that implements a simple client for the dictionary service provided by the bundles in Example 2.
• Example 4: A bundle that implements a more complex client for the dictionary service provided by the bundles in Example 2.
• Example 5: A bundle that registers a more complex spell check service that uses the dictionary service defined in Example 2.
• Example 6: A bundle that implements a client for the spell check service from Example 5; this bundle is nearly identical to dictionary client in Example 4.
• Example 7: A bundle that re-implements the spell check service of Example 5, but does so using the Gravity Service Binder, which greatly reduces the complexity of the service.

Every file that is needed for the tutorial is available in the tutorial.jar JAR file, including an Ant build script to build everything in one step.
