+Calculator Sample

+=================

+This sample implements a simple calculator using SCA components. 

+

+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 ..\..\features\tuscany-sca-manifest.jar;target\sample-calculator-equinox.jar calculator.CalculatorClient

+

+and on *nix do

+

+java -cp ../../features/tuscany-sca-manifest.jar:target/sample-calculator-equinox.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.

+

+calculator/

+  src/

+    main/

+      java/

+        calculator/

+          CalculatorService.java  - the first component, calls +-/* as 

+                                    appropriate

+          CalculatorServiceImpl.java

+          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

+          CalculatorClient.java   - starts the SCA Runtime and 

+                                    deploys the Calculator.composite. 

+                                    It then calls the deployed Calculator 

+                                    Components services

+      resources/

+        Calculator.composite      - the SCA assembly for this sample

+    test/

+      java/

+        calculator/

+          CalculatorTestCase.java - JUnit test case 

+  calculator.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

+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

+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: 1.272 sec

+

+Results :

+

+Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

+

+This shows that the Junit test cases have run successfully.
