+Calculator RMI Service Sample
+=============================
+
+This sample illustrates the use of Tuscany RMI Binding to expose component
+services as Java RMI Services. It also demonstrates how a simple Java RMI
+Client application invokes the SCA Application's services exposed as 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, 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-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 the calculator-rmi-reference 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 service
+binding with an RMI binding. SO a java client can call the service exposed
+by the SCA application using an RMI client.
+
+This sample adds a number of classes to the basic calculator sample:
+
+calculator-rmi-service/
+ src/
+ main/
+ java/
+ calculator/
+ CalculatorService.java - as calculator sample
+ CalculatorServiceImpl.java
+ AddService.java - as calculator sample
+ AddServiceImpl.java
+ SubtractService.java - as calculator sample
+ SubtractServiceImpl.java
+ MultiplyService.java - as calculator sample
+ MultiplyServiceImpl.java
+ DivideService.java - as calculator sample
+ DivideServiceImpl.java
+ CalculatorClient.java - (Not currently used) Uses the
+ java naming service to
+ look up the Calculator RMI service.
+ It then calls add, subtract, multiple
+ and divide methods on the service
+ CalculatorServer.java - starts the SCA Runtime and deploys
+ the CalculatorRMIServer.composite.
+ In doing this the SCA RMI binding
+ acts to expose the CalculatorService
+ over RMI.
+ resources/
+ CalculatorRMIServer.composite - the SCA assembly for this sample
+ test/
+ java/
+ calculator/
+ CalculatorRMIServerTestCase.java - JUnit test case
+ calculator-rmi-service.png - a pictorial representation of the
+ .composite file
+ build.xml - the Ant build file for the server
+ 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. Two
+build files are used to support client and server functions.
+
+The server starts the SCA runtime and loads the SCA calculator application
+which exposes an RMI service. 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 locates the RMI service that the SCA runtime is exposing and calls each of
+the calculator operations. 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-service
+mvn
+
+You should see the following output from the test phase.
