Hello World Web Service Service Sample
======================================
This sample demonstrates an SCA service that uses a web service binding.
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-helloworld-ws-service.jar helloworld.HelloWorldServer
and on *nix do
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-ws-service.jar helloworld.HelloWorldServer
Now the server is started you can use the helloworld-ws-reference sample to
exercise it.
Sample Overview
---------------
The sample provides a single component that is wired to a service with a
web service binding.
helloworld-ws-service/
src/
main/
java/
helloworld/
HelloWorldService.java - interface description for
HelloWorldServiceComponent
HelloWorldImpl.java - 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
resources/
wsdl/
helloworld.wsdl - the service description that describes
the exposed service
helloworldws.composite - the SCA assembly for this sample
test/
java/
helloworld/
HelloWorldServerTestCase.java - JUnit test case
helloworld-ws-service.png - a 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 using the
following commands
cd helloworld-ws-service
ant compile
ant run
You should see the following output from the run target.
run:
[java] log4j:WARN No appenders could be found for logger (org.apache.axiom.
om.util.StAXUtils).
[java] log4j:WARN Please initialize the log4j system properly.
[java] HelloWorld server started (press enter to shutdown)
As this point the SCA service is exposed as a web service by a web server
started automatically by the SCA runtime. To stop the server just press
enter.
To exercise the service run up the helloworld-ws-reference sample. Take a look at
the README in that sample and you will see you need the following commands
cd helloworld-ws-reference
ant run
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 helloworld-
ws-reference sample as Maven includes a simple ping test to make sure that the
service is available
cd helloworld-ws-service
mvn
You should see the following output from the test phase.
