+Distributed OSGi Calculator Sample

+==================================

+This sample implements a distributed calculator using Distributed OSGi (RFC 119) over SCA.

+

+The README in the samples directory (the directory above this) provides

+general instructions about building and running samples. Take a look there

+first.

+

+On Windows, run

+java -jar ..\..\modules\osgi-3.4.0-v20080605-1900.jar -configuration ..\..\features\configuration -clean -console

+

+On *Unix, run

+java -jar ../../modules/osgi-3.4.0-v20080605-1900.jar -configuration ../../features/configuration -clean -console

+

+You should see the osgi console:

+

+osgi>

+

+osgi> Jun 22, 2009 1:32:27 PM org.apache.tuscany.sca.extensibility.equinox.EquinoxServiceDiscoveryActivator start

+INFO: Equinox-based service discoverer is now configured.

+

+You can run "ss" command under the osgi> to see the status of the bundles.

+osgi> ss

+

+Then you can install and start the calculator.dosgi bundle:

+

+osgi> install file:./target/sample-dosgi-calculator.jar

+Bundle id is 181

+

+osgi> start 181

+Sample Overview

+---------------

+The application consists of two OSGi bundles:

+ * The calculator bundle: It provides the calculator service. The service is implemented by a java class that

+   consumes other services to perform the “add”, “subtract”, “multiply” and “divide” operations.

+ * The operations bundle: It provides the add/subtract/multiply/divide services.

+   (See ../samples/dosgi-calculator-operations)
