h1. {color:#003366}{*}Tuscany Samples{*}{color}
{color:#000000}The Tuscany Samples are shipped with Tuscany binary and source
releases. If you are using tuscany from a release distribution then make sure
you are looking at the documentation that corresponds to the samples as they
stood at the time of the release.{color}
{note} sort this link{note}
{color:#000000}(link to 2.0-beta){color}
If however you are working with a snapshot distribution, or using samples code
from the trunk of our source repository, then you've come to the right place,
as the documentation here reflects the curtrent status of the samples in the
trunk of our source tree.
{color:#000000}In a distribution, the samples source code is found in either a
binary or source code distribution in the samples directory, directly under the
root directory. The following sections are laid out to match the structure of
the samples directory and its subdirectories.{color}\\
{toc:outline=true|minLevel=2}
h2. getting-started
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.
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.
h3. helloworld-webapp
{warning:title=TODO} It's not at all clear how this is supposed to work once it
is in the web container - I have asked on the dev list
{warning}
h2. running-tuscany
Running something in Tuscany requires one or more contributions, and a method
of launching the contributions to make them available as services. In the
sections below is described various means of launching contributions into an
executing tuscany runtime.
h3. 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}
..\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}
../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{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}
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:
{code}
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
{warning}
see samples/????
TODO is this still true
{warning}
Running on Felix
See
[http://tuscany.apache.org/documentation-2x/running-tuscany-sca-2x-with-equinox-and-felix.html]
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
{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}
h2. learning-more
The samples found in the contributions below illustrate how to see more of SCA
and Tuscany's features in action.

to this sample directory, and do
{code}
ant compile run

OR if you don't have ant, on Windows do
{code}

*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, a simple test is present that exercise
the same logic as the client to invoke the BPEl process.
{code}
cd helloworld-bpel
