SCA Java implementation.bpel : Apache Tuscany

Introduction

This is a initial WS-BPEL component implementation that allows SCA runtime to invoke WS-BPEL executable processes in a SCA composition.
We are still working to finalize the Reference support, to allow your BPEL process to have partnerLinks pointing to SCA components.

As for creating a SCA component, below is an sample SCDL

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
	targetNamespace="http://bpel"
    xmlns:hns="http://tuscany.apache.org/implementation/bpel/example/helloworld"
    name="bpel">
    
    <component name="BPELHelloWorldComponent">
        <implementation.bpel process="hns:HelloWorld"/>
    </component>

</composite>

WS-BPEL Engine

As for a WS-BPEL engine, we are using Apache ODE. In order to properly deploy a WS-BPEL process in ODE, a deployment descriptor like the one below should be suplied with your application :

<deploy xmlns="http://www.apache.org/ode/schemas/dd/2007/03"
	xmlns:tns="http://tuscany.apache.org/implementation/bpel/example/helloworld" 
	xmlns:wns="http://tuscany.apache.org/implementation/bpel/example/helloworld.wsdl">


	<process name="tns:HelloWorld">
		<active>true</active>
		<provide partnerLink="helloPartnerLink">
			<service name="wns:HelloService" port="HelloPort"/>
		</provide>
	</process>
</deploy>

For more information on these deployment descriptors, see documentation on Deploying a process in ODE
