# Camel-K-runtime Java Example

This example shows the usage of Camel-k-runtime to run a Java route.

The route involves timer component and log component.

## How to run

You have three ways of doing this.

First approach:

    mvn exec:exec

This approach will pack and run a camel-quarkus runner.

Second approach

```
    mvn clean package
    export CAMEL_K_CONF=${project.basedir}/data/application.properties
    export CAMEL_K_ROUTES=file:${project.basedir}/data/MyRoutes.java
    java -jar target/quarkus-app/quarkus-run.jar
```

Third approach
```
    mvn clean compile quarkus:dev
```

You should get the following output in all three cases
