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.

  src/
    main/
      java/
        helloworld/
          BPELClient.java          	  - client application for  
                                            BEPELHelloWorldComponent

      resources/

          helloworld.componentType	  - helloworld bpel service description
          helloworld.composite            - the SCA assembly for this sample
          helloworld.wsdl                 - the service description that describes
                                            the bpel process

                                            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.
