Advanced Development: WildFly with Jakarta EE 10 and Beyond

Migration from Java EE 7 to Jakarta EE 10 on WildFly

Key Changes and Dependencies
Jakarta EE 10 adopts the `jakarta.*` package namespace, requiring updates to:

CDI 4.0 Enhancements
CDI 4.0 introduces:

Example: Dependency Update in `pom.xml`

jakarta.platform jakarta.jakartaee-api 10.0.0 org.wildfly wildfly-ee 30.0.0.Final

Developing Reactive Applications with WildFly and Vert.x

Vert.x Integration in WildFly
Vert.x is embedded as a subsystem in WildFly, enabling:

Event Bus Configuration
Configure the Vert.x event bus in `standalone.xml`:

true true

Reactive Application Template
Below is a Vert.x-based reactive service using WildFly’s CDI integration:

@ApplicationScoped
public class ReactiveOrderService {
@Inject
private Vertx vertx;

public Uni processOrder(Order order) {
return Uni.createFrom().item(order)
.onItem().transformToMulti(order -> vertx.eventBus().request("orders.queue", order)
)
.onItem().transform(response -> {
// Handle Vert.x event bus response
return new Order(response.body().toString());
});
}
}

Non-Blocking I/O Patterns

Key Vert.x Features in WildFly

Event Bus Clustering: Distributed event propagation across WildFly nodes.

CDI Integration: Inject `Vertx` or `EventBus` directly into CDI beans.

Metrics: Vert.x metrics exposed via WildFly’s management API.

Integrating WildFly with Quarkus for Native Compilation

Quarkus-WildFly Extension Overview
The `quarkus-wildfly` extension enables:

Trade-offs: WAR vs. Quarkus

io.quarkus quarkus-wildfly 2.0.0.Final

2. Configure WildFly Connection:

quarkus.wildfly.deployment-context=myapp
quarkus.wildfly.management-port=9990

3. Build Native Image:

./mvnw package -Dnative -Dquarkus.native.container-runtime=docker

4. Deploy to WildFly:

Example: Quarkus + Vert.x in WildFly

@ApplicationScoped
public class QuarkusVertxService {
@Inject
Vertx vertx;

public void handleEvent(String event) {
vertx.eventBus().send("quarkus.queue", event);
}
}

Extending WildFly with Custom Subsystems and SPIs

Custom Subsystem Development
1. Define Module: Create a `module.xml` for your subsystem:

2. Implement Subsystem Interface:

public class MySubsystem implements Subsystem {
@Override
public void initialize(SubsystemContext context) {
// Register MBeans, services, or connectors
}
}

3. Deploy: Place the JAR in WildFly’s `modules/system/layers/base/com/example/subsystem/main`.

JCA Connector Example
Extend WildFly’s JCA framework to add a custom resource adapter:

@MessageEndpoint(activationSpec = MyActivationSpec.class)
public class MyMessageEndpoint implements MessageListener {
@Override
public void onMessage(Message message) {
// Process message
}
}

CDI Interceptor Development
Create a custom interceptor for method logging:
