Distributed OSGi Calculator Sample ================================== This sample implements a distributed calculator using Distributed OSGi (RFC 119) over SCA. The README in the /samples directory provides general instructions about building and running samples. (where distribution-unpack-dir is the directory in which you unpacked the tuscany binary distribution archive). Take a look there first (noting at you read it that this sample is not a new style sample). On Windows, run java -jar ..\..\modules\osgi-3.5.0-v20090520.jar -configuration ..\..\features\configuration -clean -console On *Unix, run java -jar ../../modules/osgi-3.5.0-v20090520.jar -configuration ../../features/configuration -clean -console You should see the osgi console: osgi> 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 198 osgi> start 198 Nov 4, 2009 9:40:00 AM calculator.dosgi.impl.CalculatorActivator start INFO: Starting calculator.dosgi_1.0.0 [198] Nov 4, 2009 9:40:01 AM calculator.dosgi.impl.CalculatorActivator start INFO: Registering calculator.dosgi.CalculatorService Nov 4, 2009 9:40:01 AM calculator.dosgi.impl.CalculatorActivator getBundle INFO: calculator.dosgi.operations.AddService is loaded by bundle: calculator.dos gi Nov 4, 2009 9:40:01 AM org.apache.tuscany.sca.node.impl.NodeImpl start INFO: Starting node: calculator.dosgi domain: tuscany.apache.org Nov 4, 2009 9:40:01 AM org.apache.tuscany.sca.node.impl.NodeFactoryImpl loadCont ributions INFO: Loading contribution: bundleentry://198.fwk15020296/ log4j:WARN No appenders could be found for logger (org.apache.axiom.om.util.StAX Utils). log4j:WARN Please initialize the log4j system properly.

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.
