== Maven coordinates

https://code.quarkus.io/?extension-search=camel-quarkus-hazelcast[Create a new project with this extension on code.quarkus.io, window="_blank"]

Or add the coordinates to your existing project:

[source,xml]
----
<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-hazelcast</artifactId>
</dependency>
----

Check the xref:user-guide/index.adoc[User guide] for more information about writing Camel Quarkus applications.

== SSL in native mode

This extension auto-enables SSL support in native mode. Hence you do not need to add
`quarkus.ssl.native=true` to your `application.properties` yourself. See also
https://quarkus.io/guides/native-and-ssl[Quarkus SSL guide].

== Additional Camel Quarkus configuration

This extension leverages https://github.com/hazelcast/quarkus-hazelcast-client[Hazelcast Client for Quarkus]. The configuration of the HazelcastInstance is managed by the extension. To configure Hazelcast Instance, check the https://github.com/hazelcast/quarkus-hazelcast-client[Hazelcast Client for Quarkus] guide.

*Please note that the camel-quarkus-hazelcast component works only with the client mode.*

To use the Hazelcast instance in the camel-quarkus-hazelcast component, you should configure the component with :

* The HazelcastInstance initialized by the Hazelcast Client for Quarkus
* The component mode as : "client"

Example of configuration for HazelcastMap component:

[source,java]
----
    @Inject
    HazelcastInstance hazelcastInstance;

    @Produces
    @ApplicationScoped
    @Unremovable
    @Named("hazelcast-map")
    HazelcastDefaultComponent hazelcastMap() {
        final HazelcastMapComponent hazelcastComponent = new HazelcastMapComponent();
        hazelcastComponent.setHazelcastInstance(hazelcastInstance);
        hazelcastComponent.setHazelcastMode(HazelcastConstants.HAZELCAST_CLIENT_MODE);
        return getHazelcastComponent(hazelcastComponent);
    }
