The first step is to give our dictionary a name, such as
LeaveApprovalRules,
and a
corresponding
Package
name.
In addition, we need to specify the
Input
and
Output
facts that we will pass to our
decision service. For our purpose, we will pass in a single leave request. The rule
engine will then apply the rules that we define and update the status of the
leave request to either
Approved
or
Manual
(to indicate the request needs to be
manually approved).
So we need to define a single input fact and output fact, both of type
leaveRequest
.
To do this, click on the
plus
symbol (marked in the preceding screenshot), and
select
Input
.
This will bring up the standard
Type Chooser
window; browse the
LeaveRequest.
xsd
and select
leaveRequest
. Do the same again to specify an
Output
fact.
When creating facts based on an XML schema, the rules editor will
generate corresponding JAXB Java classes and place them in the specified
Package
. It is a good practice to specify a different package name for
every XML schema to prevent conflicting class definitions.
Next, click the
Advanced
tab. Here we can see that JDeveloper has given the default
name
LeaveApprovalRules_DecisionService_1
to our decision service. Give it a
more meaningful name such as
LeaveApprovalDecisonService
.
