Invoking the BAM adapter through BPEL sensors
In this section, we will examine how to use BPEL sensors to invoke the BAM adapter.
Within JDeveloper, there are several modes in which we can view the BPEL process.
On the right-hand side of the title bar for the BPEL editor, there is a drop-down list
that allows us to select the viewing and editing mode.
The drop-down list shows us the three modes available:
•
•
•
BPEL
: Lets us edit and view the BPEL activities
Monitor:
Lets us edit and view sensor annotations to the BPEL process
BPA
:
Is only used with the Oracle BPA suite.
After choosing
Monitor,
we can right-click on a BPEL activity to start creating the
sensor. This brings up a pop-up menu from which we can select the
Create | Sensor
item. Note that there are also options to create other monitoring items.
