NodeA exercises this interface by calling add, subtract, multiply and +divide operations. + +In the case of add and subtract the runtime recognises that +it can't find these services locally and, using the remote (web services) +version of the default SCA binding contacts the add service running in NodeB +and the subtract service running in NodeC. + +On the command prompt where you started NodeA, you would see output of invoking the +calculator functions distributed over NodeB and and NodeC. On the command prompts +where you have started NodeB and NodeC, you would see log messages that indicate that +the add and substract services where called on these nodes respectively. + +The sample demonstrates that the calculator application can be distributed +across multiple nodes with no change to the application or to the SCA description +files. + + +calculator/ + src/ + main/ + java/ + calculator/ + CalculatorService.java - the first component, calls +-/* as + appropriate + AddService.java - adds two numbers + AddServiceImpl.java + SubtractService.java - subtracts one number from another + SubtractServiceImpl.java + MultiplyService.java - multiplies two numbers + MultiplyServiceImpl.java + DivideService.java - divides one number by another + DivideServiceImpl.java + node/ + CalculatorNode.java - runs up an sca application based on + configuration given on the command + line in the form + + CalculatorNode + + it looks for a directory name the same + as and loads the composites + there + + if = nodeA it calls the + +-/* operations otherwise it behaves + like a server and waits for service + requests + DomainNode.java - the node that provides the service + discovery mechanism to the distributed + domain + resources/ + nodeA - the SCA assembly for nodeA's part of the + calculator application + nodeB - the SCA assembly for nodeB's part of the + calculator application + nodeC - the SCA assembly for nodeB's part of the + calculator application + test/ + java/ + calculator/ + DomainInMemoryTestCase.java - JUnit test case which runs all of the + separate ndes in a single VM for test + purposes + calculator-distributed.png - a pictorial representation of the sample + .composite files + build.xml - the Ant build file + pom.xml - the Maven build file + + +Building And Running The Sample Using Ant +----------------------------------------- +With the binary distribution the sample can be built and run using Ant as +follows + +cd calculator-distributed +ant compile +ant runDomainNode +ant runNodeB +ant runNodeC +ant runNodeA + +You should see the following output from the four separate command prompt: + +runDomainNode: + [java] log4j:WARN No appenders could be found for logger (org.apache.axiom. +om.util.StAXUtils). + [java] log4j:WARN Please initialize the log4j system properly. + [java] 23-Aug-2007 17:40:40 org.apache.tuscany.sca.http.jetty.JettyServer a +ddServletMapping + [java] INFO: Added Servlet mapping: http://localhost:8080/ServiceDiscoveryC +omponent/ServiceDiscovery + [java] Domain node started (press enter to shutdown) + [java] Registering service: [mydomain nodeB AddServiceComponent org.apache. +tuscany.sca.assembly.SCABinding http://localhost:8085/AddServiceComponent] + [java] Registering service: [mydomain nodeC SubtractServiceComponent org.ap +ache.tuscany.sca.assembly.SCABinding http://localhost:8086/SubtractServiceCompon +ent] + [java] Finding service: [mydomain SubtractServiceComponent org.apache.tusca +ny.sca.assembly.SCABinding] + [java] Matching service url: http://localhost:8086/SubtractServiceComponent + + [java] Finding service: [mydomain AddServiceComponent org.apache.tuscany.sc +a.assembly.SCABinding] + [java] Matching service url: http://localhost:8085/AddServiceComponent + [java] Java Result: 1 +Terminate batch job (Y/N)?
