+# DMN + Quarkus example with model included in different jar
+
+## Description
+
+A simple DMN service to evaluate a model (traffic violation) that is imported from a different jar.
+
+Demonstrates DMN on Kogito capabilities, including REST interface code generation.
+
+## Installing and Running
+
+### Prerequisites
+
+You will need:
+  - Java 11+ installed
+  - Environment variable JAVA_HOME set accordingly
+  - Maven 3.8.6+ installed
+
+When using native image compilation, you will also need:
+  - [GraalVM 19.3.1](https://github.com/oracle/graal/releases/tag/vm-19.3.1) installed
+  - Environment variable GRAALVM_HOME set accordingly
+  - Note that GraalVM native image compilation typically requires other packages (glibc-devel, zlib-devel and gcc) to be installed too.  You also need 'native-image' installed in GraalVM (using 'gu install native-image'). Please refer to [GraalVM installation documentation](https://www.graalvm.org/docs/reference-manual/aot-compilation/#prerequisites) for more details.
+
+### Compile and Run in Local Dev Mode
+
+```
+cd ./dmn-consumer-example
+mvn clean compile quarkus:dev
+```
+
+(This requires a previous installation of `dmn-resource-jar`)
+
+### Package and Run in JVM mode
+
+```
+mvn clean package
+java -jar ./dmn-consumer-example/target/quarkus-app/quarkus-run.jar
+```
+
+or on Windows
+
+```
+mvn clean package
+java -jar .\dmn-consumer-example\target\quarkus-app\quarkus-run.jar
+```
+
+### Package and Run using Local Native Image
+Note that this requires GRAALVM_HOME to point to a valid GraalVM installation
+
+```
+mvn clean package -Pnative
+```
+
+To run the generated native executable, generated in `./dmn-consumer-example/target/`, execute
+
+```
+./dmn-consumer-example/target/dmn-consumer-example-runner
+```
+
+Note: This does not yet work on Windows, GraalVM and Quarkus should be rolling out support for Windows soon.
+
+## OpenAPI (Swagger) documentation
+[Specification at swagger.io](https://swagger.io/docs/specification/about/)
+
+You can take a look at the [OpenAPI definition](http://localhost:8080/openapi?format=json) - automatically generated and included in this service - to determine all available operations exposed by this service. For easy readability you can visualize the OpenAPI definition file using a UI tool like for example available [Swagger UI](https://editor.swagger.io).
+
+In addition, various clients to interact with this service can be easily generated using this OpenAPI definition.
+
+When running in either Quarkus Development or Native mode, we also leverage the [Quarkus OpenAPI extension](https://quarkus.io/guides/openapi-swaggerui#use-swagger-ui-for-development) that exposes [Swagger UI](http://localhost:8080/swagger-ui/) that you can use to look at available REST endpoints and send test requests.
+
+## Test DMN Model using Maven
+
+Validate the functionality of DMN models before deploying them into a production environment by defining test scenarios in Test Scenario Editor. 
+
+To define test scenarios you need to create a .scesim file inside your project and link it to the DMN model you want to be tested. Run all Test Scenarios, executing:
+
+```sh
+cd ./dmn-consumer-example
+mvn clean test
+```
+See results in surefire test report `target/surefire-reports` 
+
+(This requires a previous installation of `dmn-resource-jar`)
+
+## Example Usage
+
+Once the service is up and running, you can use the following example to interact with the service.
+
+### POST /Traffic Violation
+
+Returns penalty information from the given inputs -- driver and violation:
+
+Given inputs:
+
+```json
+{
+    "Driver":{"Points":2},
+    "Violation":{
+        "Type":"speed",
+        "Actual Speed":120,
+        "Speed Limit":100
+    }
+}
+```
+
+Curl command (using the JSON object above):
+
+```sh
+curl -X POST -H 'Accept: application/json' -H 'Content-Type: application/json' -d '{"Driver":{"Points":2},"Violation":{"Type":"speed","Actual Speed":120,"Speed Limit":100}}' http://localhost:8080/Traffic%20Violation
+```
+or on Windows:
+
+```sh
+curl -X POST -H "Accept: application/json" -H "Content-Type: application/json" -d "{\"Driver\":{\"Points\":2},\"Violation\":{\"Type\":\"speed\",\"Actual Speed\":120,\"Speed Limit\":100}}" http://localhost:8080/Traffic%20Violation
+```
+
+As response, penalty information is returned.
+
+Example response:
+
+```json
+{
+  "Violation":{
+    "Type":"speed",
+    "Speed Limit":100,
+    "Actual Speed":120
+  },
+  "Driver":{
+    "Points":2
+  },
+  "Fine":{
+    "Points":3,
+    "Amount":500
+  },
+  "Should the driver be suspended?":"No"
+}
+```
+
+The difference from the [dmn-quarkus-example](../dmn-quarkus-example) is that, in the current one, the `Traffic Model.dml` is defined in a different jar.
