+==============================
+This sample demonstrates an SCA service 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 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-service-erlang.jar helloworld.HelloWorldServer
+
+and on *nix do
+
+java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-service-erlang.jar helloworld.HelloWorldServer
+
+Now the server is started you can use the helloworld-reference-erlang sample to
+exercise it.
+
+Sample Overview
+---------------
+The sample provides a single component that is wired to a service with a
+Erlang binding.
+
+helloworld-service-erlang/
+ src/
+ main/
+ java/
+ helloworld/
+ HelloWorldService.java - interface description for
+ HelloWorldServiceComponent
+ HelloWorldImpl.java - component implementation
+ HelloWorldServer.java - starts the SCA Runtime and
+ deploys the helloworlderlangservice
+ .composite and then waits for the
+ service to be called via Erlang
+ resources/
+ helloworlderlangservice.composite - the SCA assembly for this sample
+
+ test/
+ java/
+ helloworld/
+ HelloWorldErlangServerTestCase.java - JUnit test case
+ dynaignore/ - internal Java classes for ignoring test
+ in case of missing Erlang/OTP distribution
+ helloworld-service.png - a pictorial representation of the
+ sample .composite file
+ build.xml - the Ant build file
+ 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 using the
+following commands
+
+cd helloworld-service-erlang
+ant compile
+ant run
+
+You should see the following output from the run target.
+
+run:
+ [java] EPMD server started
+ [java] 2009-05-26 11:59:07 org.apache.tuscany.sca.node.impl.NodeImpl <init>
+ [java] INFO: Creating node: helloworlderlangservice.composite
+ [java] 2009-05-26 11:59:08 org.apache.tuscany.sca.node.impl.NodeImpl configureNode
+ [java] 2009-05-26 11:59:08 org.apache.tuscany.sca.node.impl.NodeImpl configureNode
+ [java] 2009-05-26 11:59:08 org.apache.tuscany.sca.node.impl.NodeImpl start
+ [java] INFO: Starting node: helloworlderlangservice.composite
+ [java] HelloWorld server started (press enter to shutdown)
+
+
+As this point the SCA service is exposed as a Erlang module via Erlang RPC which is
+started automatically by the SCA runtime. To stop the server just press
+enter.
+
+To exercise the service run up the helloworld-reference-erlang sample. Take a look at
+the README in that sample and you will see you need the following commands
+
+cd helloworld-reference-erlang
+ant run
+
+Building Sample Using Maven
+-------------------------------------------
+With either the binary or source distributions the sample can be built
+using Maven as follows.
+
+cd helloworld-service-erlang
+mvn
+
+You should see the following output
+
+...
+[INFO] ------------------------------------------------------------------------
+[INFO] BUILD SUCCESSFUL
+[INFO] ------------------------------------------------------------------------
+[INFO] Total time: 15 seconds
+[INFO] Finished at: Wed Jul 02 12:50:24 BST 2008
+[INFO] Final Memory: 13M/51M
+[INFO] ------------------------------------------------------------------------
+
+
+This shows that the module has compiled successfully.
