In-Depth Information
a process element also has several attributes. The basic structure of the BPEL code
is as follows:
<process name="ncname">
<!-- Activities -->
</process>
Every BPEL has activities such as
<receive>
,
<reply>
, and
<invoke>
. Activities
describe different action steps in a BPEL process that enable the interaction with ex-
ternal and internal services. Note, that Oracle BPEL also allows interaction with JCA
adapters and EDN.
The most important concepts of BPEL are activities, partner links, variables, correla-
tion, and handlers. The BPEL processes expose WSDL interface for consumption as
web services. WSDL specifies the location of the service, the operations the service
provides, and describes how to access them.
