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-dynamic-calculator.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 <20>add<64>, <20>subtract<63>, <20>multiply<6C> and <20>divide<64> operations.
|
||
* The operations bundle: It provides the add/subtract/multiply/divide services.

Building And Running The Test Case Using Maven
|
||
-------------------------------------------
|
||
With either the binary or source distributions the sample can be built and run
|
||
using Maven as follows.
|
||
|
||
cd dosgi-calculator
|
||
mvn
|
||
