+The Apache Tuscany SCA Samples
+==============================
+The Apache Tuscany SCA samples are built as part of the main Maven build and 
+run, using the provided JUnit test cases, as tests in the Maven build.
+
+In the binary distribution of Apache Tuscany most samples can also 
+be run using the provided Ant build.xml files. These show the samples running 
+from a simple main() method without the need for a JUnit test case. 
+
+In these notes text that appears in angled brackets like this <example> means 
+that you need to make a choice and provide your own text at that point. 
+
+These simple samples have been created with the intention of illustrating the 
+usage of the SCA API and annotations and certainly not to levels of SCA component 
+abstraction.  In real life situations you should use SCA to assemble real and 
+usually bigger components, and when you do that you'll get all the benefits of 
+SCA, bindings, policies, integration in an SOA environment etc..
+
+Sample Overview
+---------------
+The samples generally show off different features of the SCA runtime
+and the extensions that come packaged with it.
+
+binding-ws-calculator              - Calculator running inside a web app also 
+                                     showing webservices binding
+
+calculator                         - Calculator built with java components and 
+                                     local wires. 
+
+calculator-equinox                 - Calculator running inside a Equinox OSGi runtime
+
+calculator-osgi                    - Calculator running inside a OSGi runtime
+
+calculator-rmi-reference           - The calculator configured to talk RMI to
+                                     the calculator-rmi-service sample
+calculator-rmi-service             - The calculator configured to accept RMI
+                                     requests from calculator-rmi-reference
+
+implementation-java-calculator
+
+
+Sample Layout
+-------------
+All sample directories are organized in the same way based on the default 
+project template provided by Maven. For example, take a look at the calculator 
+sample;
+
+calculator/        
+  src/              - Holds all of the source files for the sample
+    main/           - Groups together the files that implement the sample 
+      java/         - Java source files
+      resources/    - Non java resource files such as composte files
+    test/           - Groups together files that provide sample tests
+      java          - Java test sources files. Usually JUnit test cases
+  target/           - Holds the files generated when the sample is built
+    classes/        - For example, Java class files
+    test-classes/   - classes from src/test and other test files
+
+Getting Ready To Build
+----------------------
+You will need to install the following software before you start. 
+
+J2SE Development Kit (JDK) 5.0
+Apache Ant 1.7.1                - if you are going to use Ant 
+Apache Maven 2.0.9              - if you are going to use Maven
+
+Java and Ant and/or Maven binary directories must be present in your PATH so 
+that their executable programs are available in your environment. You may 
+find it useful to use a script to set up your environment, for example;
+
+For UNIX:
+  JAVA_HOME=/<installation_directory>
+  ANT_HOME=/<installation_directory>/apache-ant-1.7.0
+  MAVEN_HOME=/<installation_directory>/maven-2.0.6
+  export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$MAVEN_HOME/bin:$PATH
+
+For Windows:
+  set JAVA_HOME=C:\<installation_directory>
+  set ANT_HOME=C:\<installation_directory>\apache-ant-1.7.0
+  set MAVEN_HOME=C:\<installation_directory>\maven-2.0.6
+  set PATH=%JAVA_HOME%\bin;%ANT_HOME%\bin;%MAVEN_HOME%\bin;%PATH%
+
+
+Building And Running The SCA Samples Using Ant
+----------------------------------------------
+The build.xml files provided with the Apache Tuscany SCA samples are designed 
+to work with the binary distribution. They rely on the tuscany-sca-manifest.jar
+to describe the class path and this jar is only provided as part of the 
+binary distribution.
+
+The binary distribution of SCA also includes precompiled versions of each sample. 
+If you look in the target directory of each sample you will see this jar file. To
+run a sample based on all of the precompiled artifacts all you have to do is:
+
+cd <sampledir>
+ant run
+
+Check each <sampledir>/README file as some samples require that two progams are
+run to get the desired result, for example, the two samples that show how
+to build extensions are run from their associated application samples. 
+
+If you want to rebuild a sample, for example, if you have changed it, do the
+following:
+
+cd <sampledir>
+ant compile
+
+Once the sample is built you have the option of running the sample in whatever 
+way best suits you. Two alternatives are provided in the ant build files.
+
+The compile target builds the class files and then builds the jar so you can use 
+the same command as before:
+
+ant run
+
+This will use the generated jar to run the samples. The command line version of
+this is:
+
+on Windows
+
+java -cp ..\..\features\tuscany-sca-manifest.jar;target\<sample jar file> <sample runnable class>
+
+for example : java -cp ..\..\features\tuscany-sca-manifest.jar;target\sample-calculator.jar calculator.CalculatorClient
+
+on *nix 
+
+java -cp ../../features/tuscany-sca-manifest.jar:target/<sample jar file> <sample runnable class>
+
+for example : java -cp ../../features/tuscany-sca-manifest.jar:target/sample-calculator.jar calculator.CalculatorClient
+
+
+You can use the compiled classes directly using
+
+ant run-classes
+
+The command line version of this is:
+
+on Windows
+
+java -cp ..\..\features\tuscany-sca-manifest.jar;target\classes <sample runnable class>
+
+for example : java -cp ..\..\features\tuscany-sca-manifest.jar;target\classes calculator.CalculatorClient
+
+on *nix 
+
+java -cp ../../features/tuscany-sca-manifest.jar:target/classes <sample runnable class>
+
+for example : java -cp ../../features/tuscany-sca-manifest.jar:target/classes calculator.CalculatorClient
+
+The class specified on the command of course depends on which sample you want to 
+run. In the examples we have used we are running the CalculatorClient from the calculator sample. 
+
+
+Building And Running The SCA Samples Using Maven
+------------------------------------------------
+
+The Maven build process will work from both source and binary distributions. 
+To build and test all of the Apache Tuscany SCA sources, including the samples,
+do the following.
+
+cd sca
+mvn
+
+This will take a little while to complete. Experience with Maven tells us that 
+sometimes there are problems downloading the dependencies that Apache Tuscany 
+SCA requires. If Maven reports that it cannot download required dependencies 
+try running the Maven build again. 
+
+Once you have all of the source built you can build and run each sample 
+independently if required.
+
+cd <sampledir>
+mvn
+
+When using Maven the samples are run within JUnit test cases and so you will 
+sometimes not see any test output. You will always see an indication of test 
+success or failure. 
+
+Using The Samples In An IDE
+---------------------------------------------
+The easiest way to use the samples in an IDE is to use Maven to generate all 
+of the IDE project files for you automatically. This works best if you 
+generate IDE projects for all of the Apache Tuscany modules. You can then 
+include the ones you are interested in working with in you IDE. 
+
+To build IDE project files for all of the modules in Apache Tuscany SCA;
+
+cd sca 
+
+If you are an Eclipse user do the following
+
+mvn -Peclipse
+
+If you are an IDEA user do the following 
+
+mvn idea:idea
+
+These commands generate project files for each module in Apache Tuscany SCA. 
+The modules you are interested in can now be included in your IDE, for example,
+in Eclipse, if you create a new Java project and use the option to "create a 
+new project from existing source" you can specify an SCA module directory, 
+which includes the generated project files, and Eclipse will treat it like any
+other Java project. 
+
+Using The Samples In An IDE Without Maven
+-----------------------------------------
+We don't provide any IDE project files with our distributions so you will have to 
+import the sample files into your IDE manually. Here's an example of how it can be 
+done using Eclipse.
+ 
+In a new or existing workspace
+    Create a new java project to represent the sample you want to work on, e.g.
+        calculator
+    Import all of the sample code and resources into this project, e.g.
+        File, Import and then select tuscany-sca-1.0-incubating\samples\calculator from the filesystem
+    Configure the source path to include
+        src/main/java
+        src/main/resources
+    Configure the output folder to be
+        calculator/target
+    Configure the build path to include the manifest jar tuscany-sca-manifiest.jar provided in
+        features
+     If you select calculator.CalculatorClient.java and run as "Java Application" you should see
+        3 + 2=5.0
+        3 - 2=1.0
+        3 * 2=6.0
+        3 / 2=1.5
+
+The details of how to do this for other development environments will
+vary but the process will be similar.
