| * Implementation of the ODE {@link org.apache.ode.bpel.iapi.EndpointReferenceContext} |
| * interface used by the BPEL engine to convert XML descriptions of endpoint |
| * references (EPRs) into Java object representations. In the JBI context all |
| * endpoint references are considered to be JBI |
| * {@link javax.jbi.servicedesc.ServiceEndpoint}s are resolved by using the |
| * {@link javax.jbi.component.ComponentContext#resolveEndpointReference(org.w3c.dom.DocumentFragment)} |
| * method. Note that is is possible to resolve both "internal" and "external" |
| * endpoint in this manner. The schema to the internal end-point representation |
| * is described on page 50 of the JBI specification 1.0. |
