Callback JMS Sample
===================
This sample demonstrates SCA callbacks over the JMS binding. It implements the example
described in the INFOQ article:
"Can I call you back about that?" Building Asynchronous Services using Service Component Architecture
See: http://www.infoq.com/articles/async-sca
It implements a service for placing an order for some widgets, where the service is asynchronous
and the client is informed of progress via a callback interface.
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;target\sample-callbacks-jms.jar callbacks.CallbacksTestCase
and on *nix do
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-callbacks-jms.jar callbacks.CallbacksTestCase
Sample Overview
---------------
The only changes over the sample code described in the INFOQ article are to add the @Remotable annotation
to the service and callback interfaces, add the @Oneway annotation to the placeOrder and placeOrderResponse
methods, and the composite XML is changed to use <binding.jms> instead of <binding.ws>.
Building And Running The Sample Using Ant
-----------------------------------------
With the binary distribution the sample can be built and run using Ant as
follows
cd callbacks-jms
ant compile
ant run
You should see the following output from the run target.
run:
[java] client placing order: callbacks.OrderRequest@c72243
[java] service received order: callbacks.OrderRequest@1f94884
[java] client callback received order response: callbacks.OrderResponse@14ab51b
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 callbacks-jms
mvn
You should see the following output from the test phase.
-------------------------------------------------------

Running callbacks.CallbacksTestCase
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.272 sec
Results :
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
This shows that the Junit test cases have run successfully.
