Welcome Yoshimasa Tanabe (emag) as project committer

The WildFly Swarm team is pleased to announce that Yoshimasa Tanabe has been added as a core committer to the project.

Thanks for your continued contribution Yoshimasa, keep up the great work!

Arquillian Testing improvements

Previously it was necessary for your test to implement the ContainerFactory interface and provide an implementation that returns the Container that you want to be run for the test.

With this release there is an alternative. A class that implements ContainerFactory can be independent of the test class using it, such as:

public class MyTest {
  public static Archive create Deployment() {

  public static Class<? extends ContainerFactory> newFactory() throws Exception {
    return MyFactory.class;

public class MyFactory implements ContainerFactory {
  public Container newContainer(String... args) throws Exception {
    return new Container().fraction(myFraction.createDefaultFraction());

We’ve also added support for system properties being set in arquillian.xml:

<property name="javaVmArguments"></property>

Logging enhancements

System property swarm.logging now supports all logging levels, not just DEBUG and TRACE.

It’s now possible to set your own handlers in a main() for a logger:

public static void main(String[] args) throws Exception {
  Container container = new Container();

  LoggingFraction loggingFraction = new LoggingFraction()
      .consoleHandler(Level.INFO, "PATTERN")
      .fileHandler(FILE_HANDLER_KEY, "sql-file.log", Level.FINE, "%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%e%n")
      .rootLogger(Level.INFO, "CONSOLE")
      .logger("wildflyswarm.filelogger", l -> l


  JAXRSArchive deployment = ShrinkWrap.create(JAXRSArchive.class);


Drools KIE Server

Though it’s not currently part of the BOM, you can try out the Drools KIE Server by including the following dependency:


and packaging it into a WF Swarm jar to execute!


Though it’s not currently part of the BOM, you can try out the Vert.x integration by including the following dependency:


The fraction deploys a JCA adapter providing both outbound and inbound connectivity with a Vert.x instance. An application component (e.g Servlet, EJB), can send messages to a Vert.x instance using the Vert.x EventBus.


VertxConnectionFactory connFactory;

public void sendMessage() throws Exception {
    try (VertxConnection conn = connFactory.getVertxConnection()) {
        conn.vertxEventBus().send("tacos", "Hello from JCA");

Inbound connectivity is provided via a listener interface which can be implemented by a Java EE Message Driven Bean (MDB). As opposed to the default JMS listener type, the Vert.x JCA listener interface allows an MDB to receive messages from a Vert.x address.


package io.vertx.resourceadapter.examples.mdb;

import io.vertx.resourceadapter.inflow.VertxListener;
import io.vertx.core.eventbus.Message;

import java.util.logging.Logger;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;

import org.jboss.ejb3.annotation.ResourceAdapter;

@MessageDriven(name = "VertxMonitor",
        messageListenerInterface = VertxListener.class,
        activationConfig = {
                @ActivationConfigProperty(propertyName = "address", propertyValue = "tacos")
public class VertxMonitor implements VertxListener {

   private static final Logger logger = Logger.getLogger(VertxMonitor.class.getName());

   public <String> void onMessage(Message<String> message) {"Get a message from Vert.x at address: " + message.address());"Body of the message: " + message.body());

See the vert.x README notes for more information

Tutorial: Monolith to microservices

The workshop contents from the Devoxx UK lab are available now. In this lab we will introduce you to WildFly Swarm through the migration of a Java EE monolith application to microservices for parts of the stack. The services will be discoverable, provide failover with Netflix Ribbon and utilize Netflix Hystrix for circuit breaking amongst other things.
