Tuscany Samples
The Tuscany Samples samples are shipped with Tuscany binary and source releases. If you are using tuscany from a release distribution then To make sure that you are 're looking at the documentation that corresponds to the samples as they stood at the time of the release.
(link to 2.0-beta)
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.
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.
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.
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.

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 |
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.
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"
|
for example
Code Block |
---|
..\bin\tuscany.bat contribution-binding-sca-calculator
|
or on *nix platforms, from a shell prompt in the samples directory, run the command ...
Code Block |
---|
../bin/tuscany.sh contribution-binding-sca-calculator
|
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 Block |
---|
ant run-<contributionname>
|
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.
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 Block |
---|
ant run-<contributionname>
|
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
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:
<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.
osgi
The Tuscany runtime can be run in and OSGi container.
Running in Equinox
On Windows, run
Code Block |
---|
java \-jar ..\..\modules\osgi-3.5.0-v20090520.jar \-configuration ..\..\features\configuration \-clean \-console
|
On *Unix, run
Code Block |
---|
java \-jar ../../modules/osgi-3.5.0-v20090520.jar \-configuration ../../features/configuration \-clean \-console
|
You should see the osgi console:
Code Block |
---|
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.
|
You can run "ss" command under the osgi> to see the status of the bundles.
Then you can install and start contributions as bundles by doing the following:
Code Block |
---|
osgi> install file:./path/to/contribution_bundle.jar
|
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 |
Running on Felix
See http://tuscany.apache.org/documentation-2x/running-tuscany-sca-2x-with-equinox-and-felix.html
shell
This directory contains a sample shell program supporting simple commands to
start and stop SCA composites.
To build the sample shell do this:
To run it:
at the prompt:
Code Block |
---|
start myNode ../../applications/store/target/sample-store.jar
|
or:
Code Block |
---|
start myNode http://people.apache.org/~jsdelfino/tuscany/java/test/sample-store.jar
|
also try:
Code Block |
---|
status
stop myNode
bye
|
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 Block |
---|
./sca <scripts/test.txt
|
or
Code Block |
---|
./sca <scripts/test-remote.txt
|
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.
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 Block |
---|
cd samples/binding-jsonrpc/contribution-calculator-webapp
mvn
cp target/sample-contribution-binding-jsonrpc-calculator-webapp.war your_container_deployment-dir
|
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 Block |
---|
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<version>6.1.18</version>
</plugin>
|
For contributions that have this, for example, binding-jsonrpc/contribution-calculator-webapp, do the following
Code Block |
---|
cd samples/binding-sca/contribution-calculator
mvn jetty:run
|
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 Block |
---|
http://localhost:8080/sample-contribution-binding-jsonrpc-calculator-webapp/

This sample demonstrates an SCA service implemented by a BPEL process.
If you just want to run it to see what happens open a command prompt, navigate
to this sample directory, and do
Code Block |
---|
ant compile run
|
OR if you don't have ant, on Windows do
Code Block |

mkdir target\wsdl2java-source
