The basic package of SCA application artifacts is a contribution which for this simple sample is found in contribution-helloworld.  There's also a  directory which contains all you need to make a web application archive which can be deployed to a web container such as Tomcat, so that the sayHello service can be run in the web container. To see Tuscany in action you must launch a component withing a Tuscany runtime environment. Launching contributions is discussed in the "Running Tuscany" section below.

h3. contribution-helloworld


In this folder you'll find the simplest contribution, implemented in Java, that implements the "business logic" of saying hello to a person whose name is supplied as input to the service. This contribution contains Java implementation code offering the service String sayHello(String name), where the implementation of the service prepends "Hello" to the name and prints the result to the console.

running-tuscany

Running something in Tuscany requires one or more contributions, and a method of launching the contributions to make them available as services. The sections below describes various means of launching contributions into an executing  tuscany runtime.

command-line

To execute a sample contribution from the command line on Windows, from a command prompt in the samples directory, run the command ...

Code Block
..\bin\tuscany.bat "contribution-name"
{code}

for example

...



{code
}
..\bin\tuscany.bat contribution-binding-sca-calculator
{code}

or on \*nix platforms, from a shell prompt in the samples directory, run the command ...

...

Code Block



{code}
../bin/tuscany.sh contribution-binding-sca-calculator
{code}

h3. embedded-jse

...



This directory contains sample java launchers for the

...


tuscany sample contributions. To use the sample JSE launchers with ant execute the command

...


{code
}
ant run-<contributionname>
{code}

where run-<contributionname> is one of the targets in the build.xml file

...



To use this sample launcher to run all of the contributions as junit test cases, execute the command "mvn" in the launcher directory.

...




h3. embedded-osgi

...



The launchers implemented in the src/main/java/launchers directory each launch a specific contribution into the OSGI runtime.

...


To use this sample OSGI launcher with ant excute the command

...



{code
}
ant run-<contributionname>
{code}
where run-<contributionname> is one of the targets in the build.xml file

...



To use this sample launcher to run all of the contributions as junit test cases,

...


execute the command

...

 {code
mvn

in the launcher directory.

maven

To execute a sample contribution from Maven

look for contributions that have the following configuration in their pom.xml file:

...

}mvn{code} in the launcher directory.


h3. maven

To execute a sample contribution from Maven

look for contributions that have the following configuration in their pom.xml file:

<plugin>
<groupId>org.apache.tuscany.maven.plugins</groupId>

...


<artifactId>maven-tuscany-plugin</artifactId>

...


<version>2.0-SNAPSHOT</version>

...


</plugin>

...



For contributions that have this, for example, learning-more/binding-sca/contribution-calculator, do the following

...



cd samples/learning-more/binding-sca/contribution-calculator

...


mvn tuscany:run

...



This will launch the contribution in the Tuscany runtime and then wait. At this point you can use

...


other clients to send messages to services that the running SCA applcation exposes,

...


for example, try learning-more/calculator-scaclient.

h3.

...

 osgi

...



The Tuscany runtime can be run in and OSGi container.

...

Running in Equinox

On Windows, run

Code Block
&nbsp;


*Running in Equinox*

On Windows, run

{code}
java \-jar ..\..\modules\osgi-3.5.0-v20090520.jar \-configuration ..\..\features\configuration \-clean \-console

{code}

On \*Unix, run

...



{code
}
java \-jar ../../modules/osgi-3.5.0-v20090520.jar \-configuration ../../features/configuration \-clean \-console

{code}

You should see the osgi console:

...

osgi>

osgi> Jun 22, 2009 1:32:27 PM org.apache.tuscany.sca.extensibility.equinox.EquinoxServiceDiscoveryActivator start

INFO: Equinox-based service discoverer is now configured.

{code}

You can run "ss" command under the osgi> to see the status of the bundles.

...



{code
}
osgi> ss

{code}

Then you can install and start contributions as bundles by doing the following:

...



{code
}
osgi> install file:./path/to/contribution_bundle.jar

...

{code}

Note that contribution_bundle.jar will need an activator in order to register the bundle as a SCA contribution

shell

This directory contains a sample shell program supporting simple commands to
start and stop SCA composites.

To build the sample shell do this:

Code Block
]


h3. shell

This directory contains a sample shell program supporting simple commands to
start and stop SCA composites.

To build the sample shell do this:
{code}
mvn install
{code}
To run it:

...


{code
}
./sca
{code}

at the prompt:

...


{code
}
start myNode ../../applications/store/target/sample-store.jar
{code}
or:

...


{code
}
start myNode http://people.apache.org/~jsdelfino/tuscany/java/test/sample-store.jar
{code}
also try:

...


{code
}
status
stop myNode
bye
{code}
Starting and stopping composites is pretty fast. To see that, try the following

...


two scripts, which start/stop the sample store composite 10 times.

...


{code
}
./sca <scripts/test.txt

or

Code Block
{code}
or
{code}
./sca <scripts/test-remote.txt
{code}

The shell can also run as a Webapp. To try it install target/scashell.war in

...


a Web container, point your Web browser to [http://localhost:8080/scashell

...

]
and try the links on that page.


h3.

...

 webapp

...



To execute sample webapp based contributions (contributions that have webapp at the end of their name) you

...


can build the contribution using maven and then copy the resulting war file to your container of choice

...



For example, for binding-jsonrpc/contribution-calculator-webapp, do the following

...


{code
}
cd samples/binding-jsonrpc/contribution-calculator-webapp
mvn
cp target/sample-contribution-binding-jsonrpc-calculator-webapp.war your_container_deployment-dir
{code}

As an alternative sample webapp based contributions can be run within Jetty directly from Maven, look for

...


webapp contributions that have the following configuration in their pom.xml file:

...



{code
}
<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>maven-jetty-plugin</artifactId>
    <version>6.1.18</version>
</plugin>
{code}

For contributions that have this, for example, binding-jsonrpc/contribution-calculator-webapp, do the following

...



{code
}
cd samples/binding-sca/contribution-calculator
mvn jetty:run
{code}

This will launch the contribution in the Jetty runtime and then wait. At this point you can use

...


HTTP clients to send messages to services that the running SCA applcation exposes. For this

...


example try pointing your browser at:

...



{code
}
http://localhost:8080/sample-contribution-binding-jsonrpc-calculator-webapp/

{code}

h4. embedded-jse-async-sample-launcher


Note that the launcher simply starts and stops a node running the contribution. &nbsp;Within the contribution the CalculatorClient java class, marked with the @EagerInit annotation, runs its calculate method (marked with the @Init annotation), thereby triggering the calculation service to be performed. The calculator service is actually performed by the injected instance of CalculatorServiceProxyImpl, which uses both of its references (one for the sync service, one for the async) to perform calculations. The calculations are then performed by instances of&nbsp;CalculatorServiceSyncImpl and&nbsp;CalculatorServiceAsyncImpl. Note that the Tuscany runtime views the following two interfaces as compatible.


@Remotable
public interface CalculatorService {
&nbsp;&nbsp; &nbsp;String calculate(Integer n1);
}
{code}

@Remotable

public interface CalculatorService {

&nbsp;&nbsp; &nbsp;String calculate(Integer n1);

}

@Remotable

@AsyncInvocation

public interface CalculatorServiceAsync {

&nbsp;&nbsp; &nbsp;void calculateAsync(Integer n1, ResponseDispatch<String> response);

This sample demonstrates using a simple calculator service component which makes use of four services for the basic arithmetic functions. In this variant of the calculator sample you can see by looking in the src/main/resources/Calculator.composite xml file that the AddService is configured to be invoked using the json rpc protocol.
