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, please
check the section to build and run the sample using maven.
The sample will start the an embedded BPEL engine, deploy process and invoke it.
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
-----------------------------------------
Ant script is not supported at the moment.
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.
We first need to tweek the helloworld-bpel pom.xml in order to overcome a surefire
defect. See below the changes that need to be done on the helloworld-bpel\pom.xml
Original:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.2</version>
<configuration>
<useFile>false</useFile>
<trimStackTrace>false</trimStackTrace>
<skip>true</skip>
<!--useSystemClassLoader>true</useSystemClassLoader-->
</configuration>
</plugin>
Updated:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.2</version>
<configuration>
<useFile>false</useFile>
<trimStackTrace>false</trimStackTrace>
<useSystemClassLoader>true</useSystemClassLoader>
</configuration>
</plugin>
Now that you have the updated pom :
cd helloworld-bpel
mvn
You should see the following output from the test phase.
