+ * evaluate("System.exit(0)")
+ * (new GroovyShell()).evaluate("System.exit(0)")

+====
+
+About this Example
+------------------
+This example demonstrates two different usages of OSGi. The "hello-groovy-bundle"
+service demonstrates how to write an OSGi bundle using Groovy. It is a simple
+service that does two things when started within an OSGi container: 1) it prints
+out a message to the console, and 2) it adds a Groovy service to the OSGi context
+that can be consumed by the second example.
+
+The "hello-groovy-test-harness" service, also written in Groovy, demonstrates how
+to import and use the previous "hello-groovy-bundle" OSGi service. It locates and
+invokes the service from the first example, which results in a message being
+written to the console.
+
+
+Building this Example
+---------------------
+IMPORTANT: You must edit build.properties before building the example. There are
+three properties that must be set in build.properties:
+ groovy.bin.dir - The example requires you specify the location of your
+ groovy jar. This is how the build finds groovyc.
+ groovy.version - The example requires you specify the version of your groovy
+ jar. This is so that the jar files can be built correctly.
+ osgi.jar - The example requires you specify the location of the OSGi jar.
+ This is required to compile the code.
+
+This example was tested using the OSGi jar from Equinox 3.4, the OSGi container
+that ships with Eclipse. You can download the Equinox jar from the Equinox website
+or search for it within your Eclipse directories. The jar will have a name similar
+to : org.eclipse.osgi_3.4.0.v20080605-1900.jar
+
+Once these properties are set, simply run ant to build:
+
+ ant
+
+The build creates three jar files:
+ hello-bundle-imports-groovy.jar - OSGi bundle written in Groovy that resolves the
+ groovy Jar file from the container.
+ hello-bundle-contains-groovy.jar - OSGi bundle written in Groovy that resolves the
+ groovy Jar file from within itself. The container never sees Groovy.
+ hello-groovy-test-harness.jar - OSGi bundle that loads and tests one of the previous
+ two services.
+
+The build also prints out the file URLs of the jar files. You need these URLs to
+run the example. Also printed to the console is the command to run the Equinox
+container. The final output of the Ant script may look like this:
+
+ [echo] To run the OSGi console, run the following command:
+ [echo] java -jar ../../../../equinox-3.4/eclipse/plugins/org.eclipse.osgi_3.4.0.v20080605-1900.jar -console
+ [echo] To install these applications in the container, run the following commands in the OSGi container:
+ [echo] install file:/home/user/dev/groovy-core/target/dist/groovy-all-1.7.0.jar
+ [echo] install file:/home/user/dev/groovy-core/src/examples/osgi/build/hello-bundle-imports-groovy.jar
+ [echo] install file:/home/user/dev/groovy-core/src/examples/osgi/build/hello-bundle-contains-groovy.jar
+ [echo] install file:/home/user/dev/groovy-core/src/examples/osgi/build/hello-groovy-test-harness.jar
+ [echo] To start the applications in the container, run the following commands in the OSGi container:
+ [echo] start [bundle1] [bundle2]
+ [echo] Where [bundle1] and [bundle] are the bundle IDs printed by the console in the previous step.
+
+
+Running this Example
+--------------------
+To run the example you must start the OSGi container, install the services, and
+start the services.
+
+To start the Equinox container, invoke the OSGi jar using java:
+
+ java -jar ../../../../equinox-3.4/eclipse/plugins/org.eclipse.osgi_3.4.0.v20080605-1900.jar -console
+
+This opens an OSGi console. You should be presented with an OSGi prompt:
+
+ osgi>
+
+Type the command "ss" to get a system status:
+
+ osgi> ss
+
+ Framework is launched.
+
+ id State Bundle
+ 0 ACTIVE org.eclipse.osgi_3.4.0.v20080605-1900
+
+Install the three bundles using the "install" command and the file URLs of the
+jars built by Ant. Remember, the Ant script printed the file URLs to the console
+as part of the build (replace groovy-all with groovy for 2.5+).
+
+osgi> install file:/home/user/dev/groovy-core/target/dist/groovy-all-1.7.0.jar
+Bundle id is 1
+
+osgi> install file:/home/user/dev/groovy-core/src/examples/osgi/build/hello-bundle-imports-groovy.jar
+Bundle id is 2
+
+osgi> install file:/home/user/dev/groovy-core/src/examples/osgi/build/hello-groovy-test-harness.jar
+Bundle id is 3
+
+Run the ss command to verify the bundles loaded correctly:
+
+
+osgi> ss
+
+Framework is launched.
+
+id State Bundle
+0 ACTIVE org.eclipse.osgi_3.4.0.v20080605-1900
+1 INSTALLED groovy-all_1.7.0
+2 INSTALLED org.codehaus.groovy.osgi.hello-groovy-bundle_1.0.0
+3 INSTALLED org.codehaus.groovy.osgi.harness.hello-groovy-test-harness_1.0.0
+
+Start the bundles with the "start" command to see them working:
+
+osgi> start 1 2 3
+Groovy BundleActivator started
+1 GroovyGreeter services found.
+Hello from the Groovy Greeter!
+
+As expected, bundle 2 printed out a message from an object implemented in Groovy,
+and bundle 3 printed out a message from a service implemented in Groovy, which it
+loaded as an OSGi service from the BundleContext.
+
+You may wish to uninstall the services using the "uninstall" command:
+
+ osgi> uninstall 3 2 1
+ Groovy BundleActivator stopped
