+Calculator RMI Reference Sample
+===============================
+
+This sample illustrates the use of Tuscany RMI Binding to call reference
+services that are hosted as Java RMI services.
+
+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, first
+navigate to the calculator-rmi-service sample and do:
+
+ant run
+
+OR if you don't have ant, on Windows do
+
+java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-rmi-service.jar calculator.CalculatorServer
+
+and on *nix do
+
+java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-rmi-service.jar calculator.CalculatorServer
+
+Now you have the server running you need to open another 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-rmi-reference.jar calculator.CalculatorClient
+
+and on *nix do
+
+java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-rmi-reference.jar calculator.CalculatorClient
+
+Sample Overview
+---------------
+This sample extends the calculator sample by replacing the local wired
+connections with RMI bindings. Instead of local add, subtract, multiply and
+divide components, an RMI service implementation now provides the
+add, subtract, multiply and divide interfaces and is hosted as an RMI server.
+References specified in the .composite file include an RMI binding which targets
+this RMI server.
+
+This sample adds a number of classes to the basic calculator sample:
+
+calculator-rmi-reference/
+ src/
+ main/
+ java/
+ calculator/
+ CalculatorService.java - as calculator sample
+ AddService.java - as calculator sample
+ SubtractService.java - as calculator sample
+ MultipleService.java - as calculator sample
+ DivideService.java - as calculator sample
+ CalculatorClient.java - as calculator sample
+ CalculatorServiceImpl.java - calls the RMI service
+ that provides the target for the
+ RMI bindings in the composite
+ resources/
+ CalculatorRMIReference.composite - the SCA assembly for this sample
+ test/
+ java/
+ calculator/
+ CalculatorRMIReferenceTestCase.java - JUnit test case
+ CalculatorRMIServiceImpl.java - test RMI service to call
+ calculator-rmi-reference.png - a pictorial representation of the
+ .composite file
+ build.xml - the Ant build file for the client
+ pom.xml - the Maven build file
+
+Note. As this test creates and uses local network connections you may need to
+configure your firewall, if you are running one, to allow the test to run
+successfully.
+
+Building And Running The Sample Using Ant
+-----------------------------------------
+With the binary distribution the sample can be built and run using Ant.
+
+The server provides an RMI server that the acts as a target for the SCA RMI
+bindings. Start a new console and use the following commands.
+
+cd calculator-rmi-service
+ant compile
+ant run
+
+This will run up the server and display the following.
+
+run:
+ [java] Starting of the SCA Calculator Application exposed as RMI Services...
+ [java] ...Press Enter to Exit...
+
+The client is very similar to the calculator sample. It starts the SCA runtime
+and calls each of the calculator operations. In doing this the RMI bindings
+make calls out to the RMI server you started in the previous step. Start
+a new console and use the following commands.
+
+cd calculator-rmi-reference
+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
+
+If you now return to the console window running the server and press enter the
+server should stop.
+
+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-rmi-reference
+mvn
+
+You should see the following output from the test phase.
