Hello World Web Service and Reference using SDO Sample
======================================================
This sample demonstrates an SCA service and reference that use a web service binding which works with SDO.
The README in the samples directory (the directory above this) provides
general instructions about building and running samples. Take a look there
first.
To run this sample
------------------
This sample includes both a server and a client. First, open a command prompt to start the server.
If you are running ant do the following:
cd helloworld-ws-sdo
ant run-server
OR if you don't have ant, on Windows do
java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-helloworld-ws-sdo.jar helloworld.HelloWorldServer
and on *nix do
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-ws-sdo.jar helloworld.HelloWorldServer
You should see the following output:
Buildfile: build.xml
run-server:
[java] 30-Sep-2010 14:45:13 org.apache.tuscany.sca.node.impl.NodeImpl <init>
[java] INFO: Creating node: helloworldws.composite
[java] 30-Sep-2010 14:45:13 org.apache.tuscany.sca.node.impl.NodeImpl configureNode
[java] INFO: Loading contribution: file:/E:/td/test161b/samples/helloworld-ws-sdo/target/sample-helloworld-ws-sdo.jar
[java] 30-Sep-2010 14:45:15 org.apache.tuscany.sca.node.impl.NodeImpl start

[java] INFO: Added Servlet mapping: http://GrosMorne:8085/HelloWorldService
[java] HelloWorld server started (press enter to shutdown)
The server is now ready.
Now, open another command window to run the client.
cd helloworld-ws-sdo
ant run
OR if you don't have ant, on Windows do
java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-helloworld-ws-sdo.jar helloworld.HelloWorldClient
and on *nix do
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-ws-sdo.jar helloworld.HelloWorldClient
You should be able to see the following result:
Buildfile: build.xml
run:

Sample Overview
---------------
The sample provides a server component that exposes a service using a web service
binding, and a client component with a reference that invokes the service using a
web service binding. The binding refers to WSDL that describes the service.
helloworld-ws-sdo/
src/
main/
java/
helloworld/
HelloWorldService.java - interface description for
HelloWorldServiceComponent and
HelloWorldImpl
HelloWorldServiceComponent.java - client component implementation
HelloWorldImpl.java - server component implementation
HelloWorldServer.java - starts the SCA Runtime and
deploys the helloworldws
.composite and then waits for the
service to be called via web services
HelloWorldClient.java - starts the SCA Runtime and
deploys the helloworldwsclient
.composite. It then calls the
HelloWorldServiceComponent

helloworld.wsdl - the service description that the
SCA reference uses to bind to service.
helloworldws.composite - the SCA assembly for the server
helloworldwsclient.composite - the SCA assembly for the client

Building And Running The Sample Using Ant
-----------------------------------------
You can build and run the sample with the binary distribution using Ant. Enter the
following commands:
cd helloworld-ws-sdo
ant
To run the sample, you need to run the server and then run the client.
First, run the server.
cd helloworld-ws-sdo
ant run-server
In a separate command prompt, run the client.
cd helloworld-ws-sdo
ant run
You should see the following output from the run target.
run:
[java] Injected helloWorldService
[java] Called getGreetings
[java] Hello David Haney
Building And Running The Sample Using Maven
-------------------------------------------
You can build and run the sample with either the binary or source distributions using Maven.
Please note that you do not need to start the server in this case since Maven does this for you.
Enter the following commands:
cd helloworld-ws-sdo
mvn
You should see the following output from the test phase.
