+=================================
+This sample demonstrates an SCA reference that uses a Erlang binding
+
+The README in the samples directory (the directory above this) provides
+general instructions about building and running samples. Take a look there
+first.
+
+In order to run Erlang samples you need to have Erlang/OTP distribution installed -
+epmd binary is required in your system path. See http://erlang.org for downloads.
+
+If you just want to run it to see what happens you need to run the server first
+so open a command prompt, navigate to the helloworld-service-erlang 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-helloworld-service-erlang.jar helloworld.HelloWorldServer
+
+and on *nix do
+
+java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-service-erlang.jar helloworld.HelloWorldServer
+
+
+Once the server is running 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-helloworld-reference-erlang.jar helloworld.HelloWorldErlangClient
+
+and on *nix do
+
+java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-reference-erlang.jar helloworld.HelloWorldErlangClient
+
+
+Sample Overview
+---------------
+The sample provides a component that has a reference with a Erlang binding.
+The binding refers to Erlang module and communicates with a service
+exposed by the helloworld-service-erlang sample.
+
+helloworld-reference-erlang/
+ src/
+ main/
+ java/
+ helloworld/
+ HelloWorldImpl - HelloWorld service implementation
+ HelloWorldService.java - interface description for
+ HelloWorldServiceComponent
+ HelloWorldServiceComponent.java - component implementation
+ HelloWorldErlangClient.java - starts the SCA Runtime and
+ deploys the helloworldwserlangclient
+ .composite. It then calls the
+ HelloWorldServiceComponent
+ resources/
+ helloworlderlangreference.composite - the SCA assembly for this sample
+ helloworlderlangservice.composite - the SCA assembly for the server
+ that is used by the JUnit tests
+ logging.properties - log4j configuration file
+ test/
+ java/
+ helloworld/
+ HelloWorldErlangClientTestCase.java - JUnit test case
+ dynaignore/ - internal Java classes for ignoring test
+ in case of missing Erlang/OTP distribution

+ 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. Before
+you do this start up the service that the reference will talk to. To do this
+run up the helloworld-service-erlang test. Take a look at the README in that sample
+and you will see you need the following commands
+
+cd helloworld-service-erlang
+ant run
+
+Once done you can now compile and run this sample using the following commands;
+
+cd helloworld-reference-erlang
+ant compile
+ant run
+
+You should see the following output from the run target.
+
+run:
+ [java] 2009-05-26 12:03:54 org.apache.tuscany.sca.node.impl.NodeImpl <init>
+ [java] INFO: Creating node: helloworlderlangreference.composite
+ [java] 2009-05-26 12:03:55 org.apache.tuscany.sca.node.impl.NodeImpl configureNode

+ [java] INFO: Starting node: helloworlderlangreference.composite
+ [java] Hello World
+ [java] 2009-05-26 12:03:56 org.apache.tuscany.sca.node.impl.NodeImpl stop
+ [java] INFO: Stopping node: helloworlderlangreference.composite
+
+BUILD SUCCESSFUL
+
+
+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 using Maven you don't need to run the helloworld-
+service-erlang sample first as the JUnit test does this for you.
+
+cd helloworld-reference-erlang
+mvn
+
+You should see the following output from the test phase.
+
+Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.569 sec
+
+Results :
+
+Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
+
+
+This shows that the Junit test cases have run successfully.
