Simple Callback Sample
|
|
======================
|
|
This sample demonstrates asynchronous messaging using a callback.
|
|
|
|
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-simple-callback.jar simplecallback.SimpleCallbackClient
|
|
|
|
and on *nix do
|
|
|
|
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-simple-callback.jar simplecallback.SimpleCallbackClient
|
|
|
|
|
|
Sample Overview
|
|
---------------
|
|
The sample provides a single composite with two components. MyClientComponent is
|
|
wired to MyServiceComponent. The interface of MyServiceComponent describes one
|
|
method as ONEWAY and with a callback semantic. When a message passes from
|
|
client to service the response is returned via the callback asynchronously.

|
|
MyServiceCallback.java - service callback interface, implemented by the

|
client
|
|
MyServiceImpl.java - implements the service interface
|
|
SimpleCallbackClient.java - starts the SCA Runtime and
|
|
deploys the simplecallback.composite.
|
|
It then calls MyClientComponent which in turn
|
|
calls MyServiceComponent

|
Building And Running The Sample Using Ant
|
|
-----------------------------------------
|
|
With the binary distribution the sample can be built and run using Ant as
|
|
follows
|
|
|
|
cd simple-callback
|
|
ant compile
|
|
ant run
|
|
|
|
You should see the following output from the run target.
|
|
|
|
run:
|
|
[java] Main thread Thread[main,5,main]
|
|
[java] Work thread Thread[pool-1-thread-1,5,main]
|
|
[java] Result: -> someMethod -> receiveResult
|
|
|
|
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 simple-callback
|
|
mvn
|
|
|
|
You should see the following output from the test phase.
