Binding Echo Sample Application
===============================
This sample demonstrates how to use the new binding extension 
binding-echo

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;..\binding-echo\target\sample-binding-echo.jar;target\sample-binding-echo-appl.jar echo.client.EchoBindingClient

and on *nix do

java -cp ../../lib/tuscany-sca-manifest.jar:../binding-echo/target/sample-binding-echo.jar:target/sample-binding-echo-appl.jar echo.client.EchoBindingClient

This looks like a long command. The three things we add to the classpath are

tuscany-sca-manifest.jar - all of the standard Tuscany SCA runtime and 
                           extension classes
sample-binding-echo.jar  - the new echo binding extension implementation
sample-binding-echo-appl - the application that uses the echo binding                         


Sample Overview
---------------
This sample contains an application (client and server code) that uses
an SCA binding that simply echoes back any messages that are sent to it. 

binding-echo-appl/
  src/
    main/
      java/
        echo/
          appl/
            Echo.java              - interface definition for the sample  
                                     reference and service
            EchoComponentImpl.java - sample component implementation with 
                                     echo binding reference
          client/
            EchoBindingClient.java - sample client
      resources/
        EchoBindingApplication.composite  - the SCA assembly for this sample
    test/
      java/ 
        echo
          appl/
            EchoApplTestCase.java  - sample JUnit test case for the sample 
                                     client
  binding-echo-appl.png            - 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 as 
follows.

cd binding-echo-appl
ant compile
ant run

You should see the following output from the run target.

run:
     [java] Returned message: foo
     [java] Echo reference = foo
     [java] Returned message: baa
     [java] Echo service = baa


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 binding-echo-appl
mvn

You should see the following output from the test phase.

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running echoAppl.EchoApplTestCase
Returned message: foo
Echo reference = foo
Returned message: baa
Echo service = baa
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.111 sec

Results :

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

This shows that the Junit test cases have run successfully.
