+osgi-supplychain Sample
+=======================
+
+The Tuscany OSGi supply chain sample shows using the Tuscany SCA runtime in a J2SE environment executing the SCA asynchronous API with OSGi and Java implementation types.
+
+If you just want to run it to see what happens open a command prompt, navigate
+to this sample directory and do:
+
+ant run
+
+OR if you don't have ant, on Windows do
+
+In the directory samples\osgi-supplychain use the JDK 1.5 java command to run the class supplychain.SupplyChainClient 
+
+Linux:   java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-osgi-supplychain.jar supplychain.SupplyChainClient
+Windows: java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-osgi-supplychain.jar supplychain.SupplyChainClient
+
+Results
+----------
+The sample when run should simply display on the standard output some startup messages followed by:
+
+Work thread Thread[Thread-1,5,main] - Order, submitted, fulfilled, shipped
+
+
+Sample Overview
+---------------
+
+The sample provides a Customer service with a purchaseGoods operation
+and a notifyShipment operation annotated with the SCA @OneWay annotation.
+The SupplyChainClient exercises this interface by calling the
+purchaseGoods operation. This results in messages passing to 
+the Retailer, Warehouse, and Shipper components and the result returned
+to the Customer service on a separate callback thread. The Customer
+and Shipper components are implemented as OSGi bundles which use
+implementation.osgi, while the Retailer and Warehouse components are
+implemented using implementation.java.

+
+Understanding OSGI implementation files
+---------------------------------------
+Some of the files introduced by OSGI implementation are explained below.
+
+OSG files related to customer. java are:
+OSGiCustomerComponentImpl.java: OSGi Declarative Services Implementation of the SCA Customer component. 
+OSGiCustomerImpl.java: OSGi Procedural Services Implementation of the SCA Customer component. 
+
+You notice the same pattern for shipper.java, retailer.java, SupplyChainClient.java.
+
+The rest of OSGI related files are:
+OSGiBundleImpl.java: Common code for OSGi Procedural Services Implementation of the SCA components
+ 
+resources/osgi/*.mf: Manifest files for OSGi bundles for OSGi procedural services implementation
+ 
+resources/osgi/ds/*.m:f Manifest files for OSGi bundles for OSGi declarative services implementation 
+
+resources/osgi/ds/*.xml: OSGi Declarative services component xml files
+ 
+resources/*.componentType: Component types used by OSGi implementation provider for SCA
+ 
+resources/supplychain.composite:  Composite file using OSGi and Java implementation types
+ 
+resources/supplychain.ds.composite: Composite file using OSGi (declarative services) and Java implementation types 
+ 
+Building And Running The Sample Using Ant
+-----------------------------------------
+cd osgi-supplychain
+ant compile 
+ant run
+
+you should see: 
+Buildfile: build.xml
+
+run:
+     [java] Main thread Thread[main,5,main]
+     [java] Main thread Started OSGi bundle with activator OSGiCustomerImpl
+     [java] Main thread Started OSGi bundle with activator OSGiShipperImpl
+     [java] Main thread Sleeping ...
+     [java] Work thread Thread[pool-1-thread-1,5,main] - Order, submitted, fulfilled, shipped
+
+ 
+
+
+Building And Running The Sample Using Maven 
+-------------------------------------------
+With either the binary or source distributions the sample can be built and run 
+using Maven as follows. 
+
+cd osgi-supplychain
+mvn
+
+You should see the following output from the test phase.
+
+-------------------------------------------------------
+ T E S T S

+Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.625 sec
+
+Results :
+
+Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
+
+This shows that the Junit test cases have run successfully.
