Chapter 5. DMN model execution
You can create or import DMN files in your Red Hat Process Automation Manager project using Business Central or package the DMN files as part of your project knowledge JAR (KJAR) file without Business Central. After you implement your DMN files in your Red Hat Process Automation Manager project, you can execute the DMN decision service by deploying the KIE container that contains it to KIE Server for remote access and interacting with the container using the KIE Server REST API.
For information about including external DMN assets with your project packaging and deployment method, see Packaging and deploying a Red Hat Process Automation Manager project.
5.1. Executing a DMN service using the KIE Server REST API
Directly interacting with the REST endpoints of KIE Server provides the most separation between the calling code and the decision logic definition. The calling code is completely free of direct dependencies, and you can implement it in an entirely different development platform such as Node.js
or .NET
. The examples in this section demonstrate Nix-style curl commands but provide relevant information to adapt to any REST client.
For more information about the KIE Server REST API, see Interacting with Red Hat Process Automation Manager using KIE APIs.
Prerequisites
-
KIE Server is installed and configured, including a known user name and credentials for a user with the
kie-server
role. For installation options, see Planning a Red Hat Process Automation Manager installation. You have built the DMN project as a KJAR artifact and deployed it to KIE Server. Ideally, you have built the DMN project as an executable model for more efficient execution:
mvn clean install -DgenerateDMNModel=yes
For more information about project packaging and deployment and executable models, see Packaging and deploying a Red Hat Process Automation Manager project.
- You have the ID of the KIE container containing the DMN model. If more than one model is present, you must also know the model namespace and model name of the relevant model.
Procedure
Determine the base URL for accessing the KIE Server REST API endpoints. This requires knowing the following values (with the default local deployment values as an example):
-
Host (
localhost
) -
Port (
8080
) -
Root context (
kie-server
) -
Base REST path (
services/rest/
)
Example base URL in local deployment for the traffic violations project:
http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0-SNAPSHOT
-
Host (
Determine user authentication requirements.
When users are defined directly in the KIE Server configuration, HTTP Basic authentication is used and requires the user name and password. Successful requests require that the user have the
kie-server
role.The following example demonstrates how to add credentials to a curl request:
curl -u username:password <request>
If KIE Server is configured with Red Hat Single Sign-On, the request must include a bearer token:
curl -H "Authorization: bearer $TOKEN" <request>
Specify the format of the request and response. The REST API endpoints work with both JSON and XML formats and are set using request headers:
JSON
curl -H "accept: application/json" -H "content-type: application/json"
XML
curl -H "accept: application/xml" -H "content-type: application/xml"
(Optional) Query the container for a list of deployed decision models:
[GET]
server/containers/{containerId}/dmn
Example curl request:
curl -u wbadmin:wbadmin -H "accept: application/xml" -X GET "http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0-SNAPSHOT/dmn"
Sample XML output:

Execute the model:
[POST]
server/containers/{containerId}/dmn
NoteThe attribute
model-namespace
is automatically generated and is different for every user. Ensure that themodel-namespace
andmodel-name
attributes that you use match those of the deployed model.Example curl request:
curl -u wbadmin:wbadmin -H "accept: application/json" -H "content-type: application/json" -X POST "http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0-SNAPSHOT/dmn" -d "{ \"model-namespace\" : \"https://github.com/kiegroup/drools/kie-dmn/_60B01F4D-E407-43F7-848E-258723B5FAC8\", \"model-name\" : \"Traffic Violation\", \"dmn-context\" : {\"Driver\" : {\"Points\" : 15}, \"Violation\" : {\"Type\" : \"speed\", \"Actual Speed\" : 135, \"Speed Limit\" : 100}}}"
Example JSON request:
