Distributed OSGi Calculator Sample | |
================================== | |
This sample implements a distributed calculator using Distributed OSGi (RFC 119) over SCA. | |
The README in the <distribution-unpack-dir>/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> | |
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 198 | |
osgi> start 198 | |

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. | |

With either the binary or source distributions the sample can be built and run | |
using Maven as follows. | |
cd dosgi-calculator-operations | |
