Callback Web Services Client Sample
===================================
This sample demonstrates an SCA client that sends service requests to a
remote server and receives asynchronous callbacks from the server, using
Web service bindings for the service and the 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, you need to start the
server first, so open a command prompt and navigate to the
callback-ws-service 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-callback-ws-service.jar myserver.CallbackServer
and on *nix do:
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-callback-ws-service.jar myserver.CallbackServer
Once the server is running 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-callback-ws-client.jar myapp.MyClientImpl
and on *nix do:
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-callback-ws-client.jar myapp.MyClientImpl
Sample Overview
---------------
The sample has a single component that has a reference with a service
interface and a callback interface, with Web service bindings for both
these interfaces. The service interface binding URI identifies the
service exposed by the callback-ws-service sample.

Building And Running The Sample Using Ant
-----------------------------------------
With the binary distribution the sample can be built and run using Ant.
Before you do this, run the callback-ws-service sample to start up the
service that the client will talk to. Take a look at the README in
that sample and you will see you need the following commands:
cd callback-ws-service
ant run
You can then compile and run this sample using the following commands:
cd callback-ws-client
ant compile
ant run
You should see the following output from the run target.

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. When using Maven you don't need to run the
callback-ws-service sample first as Maven does this for you. With Maven,
both client and server code run in the same JVM, which rather defeats the
purpose of this sample (to show a standalone SCA client), but it's good
enough for a unit test.
cd callback-ws-client
mvn
You should see the following output from the test phase.
