10.13. UDDI End-Point Look-Up

If a BPEL service invokes another BPEL service (or a web service end-point in general), the BPEL Engine performs a lookup by serviceQName and portName (obtained from the WSDL). The result is stored in a client-side service cache, resulting in increased performance. To prevent the client-side cache from returning "stale" information, the cache is automatically invalidated by the UDDI registry using the Subscription API whenever changes occur in the registry.
