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.

2.0-beta samples documentation

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. 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.

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.

helloworld-webapp

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 ...

..\bin\tuscany.bat "contribution-name"

for example

..\bin\tuscany.bat contribution-binding-sca-calculator

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

../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

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

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.

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

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

On *Unix, run

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

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.

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

osgi> ss

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

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

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:

mvn install

To run it:

./sca

at the prompt:

start myNode ../../applications/store/target/sample-store.jar

or:

start myNode http://people.apache.org/~jsdelfino/tuscany/java/test/sample-store.jar

also try:

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.

./sca <scripts/test.txt

or

./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

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:

<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

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:

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

learning-more

The samples found in the contributions below illustrate how to see more of SCA and Tuscany's features in action.

async

This sample  demonstrates invocation of services offered in both synchronous and asynchronous forms. Asynchroncity is possible by either callback to or polling by the original service invoker.

sample-contribution-implementation-java-calculator-async

In the composite file src/main/resources/Calculator.composite the references "calculatorServiceRefSync"  and "calculatorServiceRefAsync" make use of the alternative implementations of the Calculator service described in the CalculatorSync and CalculatorAsync components and implemented in the calculator.CalculatorServiceSyncImpl and calculator.CalculatorServiceAsyncImpljava classes.

embedded-jse-async-sample-launcher

binding-comet

binding-jsonrpc

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.

contribution-calculator

contribution-calculator-webapp

binding-rmi

In this example the caluclator function is split over two contyributions in order to demonstrate the remote method invocation binding.

contribution-calculator-reference

contribution-calculator-service

binding-sca

contribution-calculator

binding-ws

contribution-calculator

contribution-helloworld-ws-sdo

distributed-osgi

These samples demonstrate the execution of Tuscany contributions in a distributed OSGI environment.

dosgi-dynamic-calculator

dosgi-dynamic-calculator-operations

implementation-bpel

...

contribution-helloworld-bpel

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

ant compile run

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

mkdir target\classes
mkdir target\wsdl2java-source
java -cp ..\..\lib\tuscany-sca-manifest.jar org.apache.tuscany.sdo.generate.XSD2JavaGenerator -targetDirectory target/wsdl2java-source -prefix HelloWorld -noContainment -noUnsettable src/main/resources/helloworld.wsdl
java -cp ..\..\lib\tuscany-sca-manifest.jar org.apache.tuscany.tools.wsdl2java.generate.WSDL2JavaGenerator -targetDirectory target/wsdl2java-source src/main/resources/helloworld.wsdl
unzip ..\..\lib\ode-dao-jpa-ojpa-derby-1.1.zip -d target\database
javac -d target\classes -cp target\classes;..\..\lib\tuscany-sca-manifest.jar -sourcepath src\main\java;target\wsdl2java-source -target 1.5 -g -source 1.5 src\main\java\helloworld\BPELClient.java
copy src\main\resources\* target\classes
java -cp ..\..\lib\tuscany-sca-manifest.jar;target\classes;target\database helloworld.BPELClient

and on *nix do

mkdir target/classes
mkdir target/wsdl2java-source
java -cp ../../lib/tuscany-sca-manifest.jar org.apache.tuscany.sdo.generate.XSD2JavaGenerator -targetDirectory target/wsdl2java-source -prefix HelloWorld -noContainment -noUnsettable src/main/resources/helloworld.wsdl
java -cp ../../lib/tuscany-sca-manifest.jar org.apache.tuscany.tools.wsdl2java.generate.WSDL2JavaGenerator -targetDirectory target/wsdl2java-source src/main/resources/helloworld.wsdl
unzip ../../lib/ode-dao-jpa-ojpa-derby-1.1.zip -d target/database
javac -d target/classes -cp target/classes;../../lib/tuscany-sca-manifest.jar -sourcepath src/main/java;target/wsdl2java-source -target 1.5 -g -source 1.5 src/main/java/helloworld/BPELClient.java
cp src/main/resources/* target/classes
java -cp ../../lib/tuscany-sca-manifest.jar:target/classes:target/database helloworld.BPELClient

The sample will start an embedded BPEL engine, deploy a process and invoke it.

Sample Overview

The sample provides a single component that is wired to a service with a
web service binding.

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.

cd helloworld-bpel
mvn

You should see the following output from the test phase.
