+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.jar calculator.CalculatorClient
+
+and on *nix do
+
+java -cp ../../features/tuscany-sca-manifest.jar:target/sample-calculator.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.
