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. + + +src ++---main + +---java + ¦ +---supplychain + ¦ OSGiBundleImpl.java + ¦ SupplyChainClient.java + ¦ +---customer + ¦ Customer.java + ¦ JavaCustomerComponentImpl.java + ¦ OSGiCustomerComponentImpl.java + ¦ OSGiCustomerImpl.java + ¦ +---retailer + ¦ Retailer.java + ¦ JavaRetailerComponentImpl.java + ¦ OSGiRetailerComponentImpl.java + ¦ OSGiRetailerImpl.java + ¦ +---shipper + ¦ Shipper.java + ¦ JavaShipperComponentImpl.java + ¦ OSGiShipperComponentImpl.java + ¦ OSGiShipperImpl.java + ¦ +---warehouse + ¦ Warehouse.java + ¦ JavaWarehouseComponentImpl.java + ¦ OSGiWarehouseComponentImpl.java + ¦ OSGiWarehouseImpl.java + ¦ + +---resources + ¦ +---osgi + ¦ Customer.mf + ¦ Retailer.mf + ¦ Shipper.mf + ¦ Warehouse.mf + ¦ +---ds + ¦ Customer.mf + ¦ Retailer.mf + ¦ Shipper.mf + ¦ Warehouse.mf + ¦ Customer.xml + ¦ Retailer.xml + ¦ Shipper.xml + ¦ Warehouse.xml + ¦ Customer.componentType + ¦ Retailer.componentType + ¦ Shipper.componentType + ¦ Warehouse.componentType + ¦ supplychain.composite + ¦-- supplychain.ds.composite + + + build.xml - the Ant build file + pom.xml - the Maven build file + +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] Started OSGi bundle with activator OSGiCustomerImpl + [java] Started OSGi bundle with activator OSGiShipperImpl + [java] Main thread sleeping ... + [java] Work thread Thread[pool-1-thread-1,5,main] - Order, submitted, fulfi +lled, shipped + [java] Stop OSGi bundle with activator OSGiShipperImpl + [java] Stop OSGi bundle with activator OSGiCustomerImpl + + +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 +------------------------------------------------------- +Running supplychain.SupplyChainClientTestCase +Started OSGi bundle with activator OSGiCustomerImpl +Started OSGi bundle with activator OSGiShipperImpl +Sleeping ... +Work thread Thread[pool-1-thread-1,5,main] - Order, submitted, fulfilled, shippe +d +Test complete +Stop OSGi bundle with activator OSGiShipperImpl +Stop OSGi bundle with activator OSGiCustomerImpl +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 7.062 sec + +This shows that the Junit test cases have run successfully. |
