See the License for the + specific language governing permissions and limitations + under the License. +==== + +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.
