BPEL activities
BPEL processes have a series of steps and each step is an activity. BPEL process
logic is performed by the activities. For clients, BPEL processes looks like any other
web service. In other words, a BPEL process is a web service that coordinates, integ-
rates, and orchestrates the basic web services to serve a business function. OASIS
WS-BPEL specifications classify activities in the following categories:
•

: Enables the process behavior such as invoking and per-
forming web services operations, updating variables, and partner links
•
Structured activities
: Enables the control flow logic such as flow control

Creating basic activities in BPEL
Launch JDeveloper and perform the following steps to create a basic BPEL process:
1. The first step is to set up the application. In JDeveloper, the term "ap-
plication" is used for specifying the workspace. An application can have
one or more
projects
. An application has a project for defining the models
and one or more projects within the same application for accessing and
processing the models. The basic deployment unit for an SOA composite
is a
.sar
(
SOA Archive
) file that could be part of an
.ear
(
Enterprise
Archive
) file. Click on the
Application
tab on the top menu bar of
JDeveloper and then click on
New
to set up the application workspace.
2. Once we have created an application workspace, create a new project us-
ing the
File
tab on the top menu bar of JDeveloper and then click on
New
,
as shown in the following screenshot. Click on
OK
.
