<P>This is a initial WS-BPEL component implementation that allows SCA runtime to invoke WS-BPEL executable processes in a SCA composition.<BR>
We are still working to finalize the Reference support, to allow your BPEL process to have partnerLinks pointing to SCA components.</P>
<P>As for creating a SCA component, below is an sample SCDL</P>

<P>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 :</P>
