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-script.jar calculator.CalculatorClient + +and on *nix do + +java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-script.jar calculator.CalculatorClient + +Sample Overview +--------------- +The sample provides a single calculator service with a default SCA (java) +binding. The CalculatorClient exercises this interface by calling add, +subtract, multiply and divide operations. This results in messages passing +to the appropriate components in the composite across the local wires. Each +component is implemented using a different language. + +calculator-script/ + src/ + main/ + java/ + calculator/ + CalculatorService.java - the first component calls +-/* as + appropriate + CalculatorServiceImpl.java + AddService.java - adds two numbers + SubtractService.java - subtracts one number from another + MultiplyService.java - multiplies two numbers + DivideService.java - divides one number by another + CalculatorClient.java - starts the SCA Runtime and + deploys the Calculator.composite. + It then calls the deployed Calculator + Components services + resources/ + calculator/ + AddServiceImpl.js - A JavaScript implementation of the + Add component + SubtractServiceImpl.rb - A Ruby implementation of the Subtract + component + MultiplyServiceImpl.py - A Python implementation of the + Multiple component + DivideServiceImpl.groovy- A Groovy implementation of the + Divide component + Calculator.composite - the SCA assembly for this sample + + test/ + java/ + calculator/ + CalculatorTestCase.java - JUnit test case + calculator-script.png - a pictorial representation of the + sample .composite file + 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-script +ant compile +ant run + +You should see the following output from the run target. + +run: + [java] 3 + 2=5.0 + [java] 3 - 2=1.0 + [java] 3 * 2=6.0 + [java] 3 / 2=1.5 + +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 calculator-script +mvn + +You should see the following output from the test phase. + +------------------------------------------------------- + T E S T S +------------------------------------------------------- +Running calculator.CalculatorTestCase +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 5.918 sec + +Results : + +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 + +This shows that the Junit test cases have run successfully. |
