-Calculator Script Sample
-========================
-This sample implements a simple calculator using SCA components implemented
-using Java, JavaScript, Ruby, Python and Groovy.
-
-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-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

- 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.

-Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
-
-This shows that the Junit test cases have run successfully.
