It also demonstrates how a simple Java RMI +Client application invokes the SCA Application's services exposed as RMI +Services. + +The README in the samples directory (the directory above this) provides +general instructions about building and running samples. Take a look there +first. + +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 + +java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-rmi-service.jar calculator.CalculatorServer + +and on *nix do + +java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-rmi-service.jar calculator.CalculatorServer + +Now you have the server running you need to open another command prompt, navigate +to the calculator-rmi-reference sample directory and do: + +ant run + +OR if you don't have ant, on Windows do + +java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-rmi-reference.jar calculator.CalculatorClient + +and on *nix do + +java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-rmi-reference.jar calculator.CalculatorClient + + +Sample Overview +--------------- +This sample extends the calculator sample by replacing the local service +binding with an RMI binding. SO a java client can call the service exposed +by the SCA application using an RMI client. + +This sample adds a number of classes to the basic calculator sample: + +calculator-rmi-service/ + src/ + main/ + java/ + calculator/ + CalculatorService.java - as calculator sample + CalculatorServiceImpl.java + AddService.java - as calculator sample + AddServiceImpl.java + SubtractService.java - as calculator sample + SubtractServiceImpl.java + MultiplyService.java - as calculator sample + MultiplyServiceImpl.java + DivideService.java - as calculator sample + DivideServiceImpl.java + CalculatorClient.java - (Not currently used) Uses the + java naming service to + look up the Calculator RMI service. + It then calls add, subtract, multiple + and divide methods on the service + CalculatorServer.java - starts the SCA Runtime and deploys + the CalculatorRMIServer.composite. + In doing this the SCA RMI binding + acts to expose the CalculatorService + over RMI. + resources/ + CalculatorRMIServer.composite - the SCA assembly for this sample + test/ + java/ + calculator/ + CalculatorRMIServerTestCase.java - JUnit test case + calculator-rmi-service.png - a pictorial representation of the + .composite file + build.xml - the Ant build file for the server + pom.xml - the Maven build file + +Note. As this test creates and uses local network connections you may need to +configure your firewall, if you are running one, to allow the test to run +successfully. + +Building And Running The Sample Using Ant +----------------------------------------- +With the binary distribution the sample can be built and run using Ant. Two +build files are used to support client and server functions. + +The server starts the SCA runtime and loads the SCA calculator application +which exposes an RMI service. Start a new console and use the following +commands. + +cd calculator-rmi-service +ant compile +ant run + +This will run up the server and display the following. + +run: + [java] Starting of the SCA Calculator Application exposed as RMI Services... + [java] ...Press Enter to Exit... + +The client is very similar to the calculator sample + +It locates the RMI service that the SCA runtime is exposing and calls each of +the calculator operations.
