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-operations.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.
