+Calculator Distributed Sample
+=============================
+This sample implements a simple calculator using SCA components.  It uses 
+exactly the same calculator application classes as the calculator sample but 
+runs the application distributed across three nodes.
+
+A node in this sample means an instance of the Tuscany SCA java runtime running
+in a Java virtual machine. 
+
+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 four command prompts and 
+navigate to this sample directory in each one. There is one command to be run 
+in each command prompt:
+
+ant runDomain
+ant runNodeB
+ant runNodeC
+ant runNodeA
+
+Please run the commands in this order. 
+
+OR if you don't have ant, on Windows use
+
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchDomain
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchCalculatorNodeB
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchCalculatorNodeC
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchCalculatorNodeA
+
+and on *nix do
+
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchDomain
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchCalculatorNodeB
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchCalculatorNodeC
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchCalculatorNodeA
+
+
+The processes started on each of these command prompts can be ended by pressing 
+the <Enter> key.
+
+
+Sample Overview
+---------------
+The sample provides a single calculator service with a default SCA (java) 
+binding. NodeA exercises this interface by calling add, subtract, multiply and 
+divide operations. 
+
+In the case of add and subtract the runtime recognises that
+it can't find these services locally and, using the remote (web services) 
+version of the default SCA binding, contacts the add service running in NodeB 
+and the subtract service running in NodeC. 
+
+On the command prompt where you started NodeA, you see the output of invoking the 
+calculator functions distributed over NodeB and and NodeC.  On the command prompts 
+where you have started NodeB and NodeC, you see log messages that indicate that
+the add and subtract services where called on these nodes respectively.
+
+The sample demonstrates that the calculator application can be distributed
+across multiple nodes with no change to the application or to the SCA description
+files. 
+
+The domain node makes available a web application through which the contributions and 
+composites used in this sample can be navigated. One you have run "ant runDomain" you can 
+point you browser at:
+
+http://localhost:9990/ui/workspace/
+
+The contents of the sample are as follows:
+
+calculator/
+  src/
+    main/
+      java/
+        calculator/
+          CalculatorService.java  - the first component, calls +-/* as 
+                                    appropriate
+          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
+        node/
+          LaunchCalculatorNodeA.java - runs an sca node configured with the 
+                                    composite describing the main calculator
+                                    application. If you look inside this class
+                                    you will see that the node is configured
+                                    using a URL of the form:
+                                    
+                                    http://localhost:9990/node-config/NodeA
+                                    
+                                    This retrieves the information required
+                                    to configure NodeA from the domain.
+
+                                    Once the node has been started this launcher
+                                    then finds the calculator service and 
+                                    calls the various methods.
+                                    
+          LaunchCalculatorNodeB&C.java -  These launchers start nodes B and C
+                                    which runs the add and subtract services.
+                                    
+                                    Unlike NodeA though these launchers just
+                                    wait once the node has been started. They
+                                    will service incomming web service requests
+                                    as they arrive.  
+
+           LaunchDomain.java      - the node that provides the domain 
+                                    configuration to the distributed
+                                    nodes
+      resources/
+        cloud                     - The SCA composite files that describe
+                                    the configuration of each node				
+        nodeA                     - the SCA assembly for nodeA's part of the 
+                                    calculator application
+        nodeB                     - the SCA assembly for nodeB's part of the 
+                                    calculator application
+        nodeC                     - the SCA assembly for nodeC's part of the 
+                                    calculator application
+    test/
+      java/
+        calculator/
+          CalculatorDistributedTestCase.java - JUnit test case which runs all 
+                                    of the separate nodes along with the domain
+                                    in a single VM for test purposes
+  calculator-distributed.png      - a pictorial representation of the sample 
+                                    .composite files
+  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-distributed
+ant compile
+ant runDomain
+ant runNodeB
+ant runNodeC
+ant runNodeA
+
+You should see the following output from the four separate command prompt:
+
+runDomain:
+ted>ant runDomain
+Buildfile: build.xml
+

+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. When running from Maven the four nodes all run within 
+Java virtual machine. 
+
+cd calculator-distributed
+mvn
+
+You should see the following output at the end of the test phase.
