Invoking
a
service
from
a
BPEL
process
BPEL uses Partner Link for invoking synchronous and asynchronous services. BPEL
processes may alternatively use the Invoke activity that opens a port in the BPEL ser-
vice component to send and receive data.
Partner Link
Partner Link provides references to external services. Partner Link is the door for out-
side services. While editing a BPEL process, one can create a Partner Link to invoke
external services. As shown in the following screenshot, drag-and-drop the
Partner
Link
to the JDeveloper console and select the
SOA Resource Browser
for selecting
the WSDL for interacting with another web service using the standard WSDL inter-
face:
As shown in the following screenshot, select the WSDL file from your filesystem for
interacting with another web service. Other options are to locate the WSDL file from
Resource Palette
and
Application
or retrieve WSDL using the WSDL endpoint URL.
