BPEL

BPEL is a Web Service Sequencing Language. A BPEL Process defines a conversation flow chart and a BPEL Process instance is a particular conversation following the chart which consists of only WSDL-described message exchanges.

What are partnerLink Types

partnerLink:

Links to all the different WSDL-defined web services that a BPEL process instance interacts with are called partner links. They are concrete references to services that a BPEL business process interacts with.

• Links to WSDL-defined web services that are invoked by a BPEL process are called Invoked partner links.
• Similarly, links to WSDL-defined web services that can invoke a BPEL process are called Client partner links.

Each BPEL process will definitely have at least one Client partner link since a BPEL process can only be instantiated with a call from a Client partner.
