Hello World BPEL Sample
======================================
This sample demonstrates an SCA service implemented by a BPEL process.
The README in the samples directory (the directory above this) provides
general instructions about building and running samples. Take a look there
first.
If you just want to run it to see what happens open a command prompt, navigate
to this sample directory, and do
ant run
OR if you don't have ant, on Windows do
unzip ..\..\lib\ode-dao-jpa-ojpa-derby-1.1.zip -d target\database
unzip target\sample-helloworld-bpel.jar -d target\classes
java -cp ..\..\lib\tuscany-sca-manifest.jar;target\classes;target\database helloworld.BPELClient
and on *nix do
unzip ../../lib/ode-dao-jpa-ojpa-derby-1.1.zip -d target/database
unzip target/sample-helloworld-bpel.jar -d 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.
Unlike other samples that are run from a jar file, this sample is run from the
target/classes directory because Tuscany doesn't currently support running
a BPEL process file contained within a jar (see TUSCANY-1994).
Sample Overview
---------------
The sample provides a single component that is wired to a service with a
web service binding.
helloworld-bpel/
src/
main/
java/
helloworld/
BPELClient.java - client application for
BEPELHelloWorldComponent
resources/
deploy.xml - ODE deployment descriptor
helloworld.bpel - helloworld bpel process
helloworld.componentType - helloworld bpel service description
helloworld.composite - the SCA assembly for this sample
helloworld.wsdl - the service description that describes
the bpel process
log4j.properties - logging configuration
test/
java/
helloworld/
BPELHelloWorldTestCase.java - JUnit test case
helloworld-bpel.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
-----------------------------------------
With the binary distribution the sample can be built and run using Ant as
follows
cd helloworld-bpel
ant compile
ant run
You should see the following output from the run target.
run:

Total time: 36 seconds
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 exercises
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.
