+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.DomainNode
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.CalculatorNode mydomain nodeB
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.CalculatorNode mydomain nodeC
+java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.CalculatorNode mydomain nodeA
+
+and on *nix do
+
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.DomainNode
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.CalculatorNode mydomain nodeB
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.CalculatorNode mydomain nodeC
+java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.CalculatorNode mydomain nodeA
+
+
+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 would see output of invoking the 
+calculator functions distributed over NodeB and and NodeC.  On the command prompts 
+where you have started NodeB and NodeC, you would see log messages that indicate that
+the add and substract 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.

+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:

+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 from the test phase.
