| 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). | |
| NOTE: if you want this sample to exploit the dynamic distribution behaviour there is some unit test | |
| configuration that should be disabled. See the comments in OSGI-INF/remote-service/calculator-service-descriptions.xml | |
| On Windows, run | |
| java -jar ..\..\modules\osgi-3.5.0-v20090520.jar -configuration ..\..\features\configuration -clean -console -Dorg.osgi.sca.domain.registry=tribes:default | |
| On *Unix, run | |
| java -jar ../../modules/osgi-3.5.0-v20090520.jar -configuration ../../features/configuration -clean -console -Dorg.osgi.sca.domain.registry=tribes:default | |
| You should see the osgi console: | |
| osgi> | |

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

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

| 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 | |
