Binding Echo Sample Application
===============================
This sample demonstrates how to use the new binding extension
binding-echo-extension.
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-extension\target\sample-binding-echo-extension.jar;target\sample-binding-echo.jar echo.EchoBindingClient
and on *nix do
java -cp ../../lib/tuscany-sca-manifest.jar:../binding-echo-extension/target/sample-binding-echo-extension.jar:target/sample-binding-echo.jar echo.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-extension.jar - the new echo binding extension implementation
sample-binding-echo - 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/
src/
main/
java/
echo/
Echo.java - interface definition for the sample
reference and service
EchoComponentImpl.java - sample component implementation with
echo binding reference
EchoBindingClient.java - sample client
resources/
EchoBinding.composite - the SCA assembly for this sample
test/
java/
echo
EchoBindingTestCase.java - sample JUnit test case for the sample
client
binding-echo.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
ant compile
ant run
You should see the following output from the run target.
run:
[java] Passing thro invoker...
[java] Returned message: foo
[java] Echo reference = foo
[java] Passing thro invoker...
[java] Returned message: bar
[java] Echo service = bar
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
mvn
You should see the following output from the test phase.
-------------------------------------------------------
T E S T S
-------------------------------------------------------
Running echo.EchoBindingTestCase
Passing thro invoker...
Returned message: foo
Passing thro invoker...
Returned message: bar
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.811 sec
Results :
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0
This shows that the Junit test cases have run successfully.
