The image shows a diagram of a one-way message between a client BPEL process and a service BPEL process. The following actions take place:

  1. The client BPEL process has an invoke activity that sends the message.

  2. The invoke activity sends the message through a WSDL partner link to the service BPEL process. The WSDL partner link defines the interaction.

  3. The service BPEL process uses a receive activity to accept the message.
