This sample is the simplest sample other than that shown in the getting starting section. It uses the default SCA protocol for communicating between the components.

contribution-calculator

...

(for binding SCA)

The service and reference definitions in the Calculator.composite and CalculatorClient.composite files have no binding attributes, thereby defaulting to the SCA binding for communication between the running instances of the components.

This sample contains contrributions which show how the services can be offered via a web service interfaqce.

contribution-calculator (for binding-ws)

This contribution provides the four arithmetic operations in the calculator service, with the AddService being accessible as a web service via the URL http://localhost:8085/AddServiceComponent^{Image Added}, as configured in the Calculator.composite file in the contribution project.

Hello World Web Service References using SDO Sample
===================================================
This sample demonstrates an SCA reference that uses 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 is dependent on helloworld-ws-service. Open a command prompt to start
the service. If you are running ant do the following:

cd helloworld-ws-service
ant run

if you don't have ant, issue one of the following commands for windows or *nix:

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

You should see the following output:

Buildfile: build.xml

run-server:

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 helloworl.HelloWorldClient

You should be able to see the following result:

Sample Overview
---------------
The sample provides a single component that is wired to a reference with a 
web service binding. The binding refers to WSDL that identifies the service
exposed by the helloworld-ws-service sample. 

helloworld-ws-sdo/
  src/
    main/
      java/
        helloworld/
          HelloWorldService.java          - interface description for 
                                            HelloWorldServiceComponent
          HelloWorldServiceComponent.java - component implementation
          HelloWorldClient.java           - starts the SCA Runtime and 
                                            deploys the helloworldwsclient
                                            .composite. It then calls the 
                                            HelloWorldServiceComponent
      resources/
        wsdl
          helloworld.wsdl                 - the service description that the 
                                            SCA reference uses to bind to service. 
      
    test/
      java/
        helloworld/
          HelloWorldClientTestCase.java   - JUnit test case
        helloworld-ws-sdo.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
-----------------------------------------
You can build and run the sample with the binary distribution using Ant. 
Make sure that you have started helloworld-ws-service which this sample is dependent on
in a separate command window. You can either follow the instruction at the begining of this 
sample file or if you want to build and run the service, follow the README under helloworld-ws-service.

Now, let's build and run helloworld-ws-sdo sample:

cd helloworld-ws-sdo                                             
ant 
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] Injected helloWorldService
     [java] Called getGreetings
     [java] Hello World

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 helloworld-ws-service in this case since Maven does this for you.

cd helloworld-ws-sdo
mvn

You should see the following output from the test phase.
