# Evaluate, Deploy, and Test the Decision Table

## Evaluate the decision table

To assess a decision table immediately after deployment, add this method to your application class:

```java theme={null}
package org.camunda.bpm.getstarted.dmn;

@ProcessApplication("Dinner App DMN")
public class DinnerApplication extends ServletProcessApplication {

  protected final static Logger LOGGER = Logger.getLogger(DinnerApplication.class.getName());

  @PostDeploy
  public void evaluateDecisionTable(ProcessEngine processEngine) {

    DecisionService decisionService = processEngine.getDecisionService();

    VariableMap variables = Variables.createVariables()
      .putValue("season", "Spring")
      .putValue("guestCount", 10);

    DmnDecisionTableResult dishDecisionResult = decisionService.evaluateDecisionTableByKey("dish", variables);
    String desiredDish = dishDecisionResult.getSingleEntry();

    LOGGER.log(Level.INFO, "\n\nDesired dish: {0}\n\n", desiredDish);
  }

}
```

<Note>
  **Catch up: get the sources of Step-4**

  ```bash theme={null}
  git clone https://github.com/aseeflow/aseeflow-get-started-dmn.git
  git checkout -f Step-4
  ```

  Or [download as a `.zip`](https://github.com/aseeflow/aseeflow-get-started-dmn/archive/Step-4.zip).
</Note>

## Build the web application with Maven

In the Package Explorer, select `pom.xml`, right-click, and choose **Run As > Maven Install**. This generates a WAR file called `dinner-dmn-0.1.0-SNAPSHOT.war` in the `target/` directory.

<Tip>
  If the WAR file doesn't appear after the Maven build, refresh the project in your IDE.
</Tip>

## Deploy to Apache Tomcat

Copy the `dinner-dmn-0.1.0-SNAPSHOT.war` file from your Maven project to `$ASEEFLOW_HOME/server/apache-tomcat/webapps`.

Examine the Apache Tomcat server logs. Successful deployment is indicated by:

```

ENGINE-07015 Detected @ProcessApplication class 'org.camunda.bpm.getstarted.dish.DishApplication'

## Verify the deployment with Cockpit

Access Cockpit at [http://localhost:8080/camunda/app/cockpit](http://localhost:8080/camunda/app/cockpit). Log in with `demo` / `demo`. Navigate to the *Decisions* section, where your *Dish* decision table should appear as a deployed decision definition.

## Verify the evaluation with Cockpit

Select the *Dish* decision to open a dialog displaying when the decision table was evaluated.

Clicking the ID reveals the evaluation's historical data. Matched rules are highlighted, with input and output values presented in a table.

Confirm that the 5th rule matched and *Stew* appears as the desired dish output value.

## Next steps

You've successfully established a project featuring your first DMN decision table. Consider these follow-up activities:

* Review decision evaluation using the [REST API](/reference/rest/decision-definition/evaluate-by-key)
* Deepen your DMN knowledge through the [DMN Reference](/reference/dmn)
* Explore the [Decision API of the process engine](/user-guide/process-engine/decisions)
* Discover how to trigger decisions from a [BPMN business rule task](/reference/bpmn20/tasks/business-rule-task)
* Bonus: learn about the [Decision Requirements Graph](/get-started/dmn/drg)
