= Application Composer with JAX-WS and CDI
:index-group: Testing Techniques

This example shows the use of `@ApplicationComposer` annotation, in the context of a JAX-WS application.

Application Composer is an API for creating an EE application programmatically. It is very useful in a text context, so it's no wonder that it originated from here.
For more information about Application Composer, please refer to http://tomee.apache.org/tomee-8.0/docs/application-composer/index.html[Application Composer section in the documentation].
In this example, we will use `@ApplicationComposer` in the context of a JAX-WS application.

== Example

This example is a meeting planner application. It is a JAX-WS application, and it accepts incoming booking meeting requests. The application first checks if the request can be booked, books it if possible,
and returns to the caller if the request was booked (a boolean value). This is a simple, demo-purpose application, so it is greatly simplified. A book request is represented only by the meeting start date (a `java.util.Date` value).
A book request is bookable if it starts after current date.

The business logic is implemented using a `MeetingPlannerImpl` class (implementing `MeetingPlanner`). This class is a JAX-WS service, exposing the following method: `boolean book(final Date date)`.
The client will send a request, containing a date; the service will return if the request can be booked, true or false. The exposed JAX-WS service uses in addition a different feature, CDI, injecting a
business logic service class checking if the request is bookable. So, when the time will come to test the `@ApplicationComposer` annotation, we will both check that CDI worked in our programmatically
started application and that the JAX-WS service is up and running.

The business logic that checks if a request is bookable is defined by the following interface:

[source,java]
----
import java.util.Date;

public interface Agenda {
    boolean isBookable(Date d);
}
----

The implementation is a simple one, without distracting details:

[source,java]
----
import java.util.Date;

public class LazyAgenda implements Agenda {
    @Override
    public boolean isBookable(final Date d) {
        return d.after(new Date());
    }
}
----

The JAX-WS service is defined by the following interface:

[source,java]
----
import javax.jws.WebMethod;
import javax.jws.WebService;
import java.util.Date;

@WebService
public interface MeetingPlanner {

    @WebMethod(operationName = "book", exclude = false)
    boolean book(final Date date);
}
----

The class implementing this interface is:

[source,java]
----
import javax.inject.Inject;
import javax.jws.WebService;
import java.util.Date;

@WebService
public class MeetingPlannerImpl implements MeetingPlanner {
    @Inject
    private Agenda agenda;

    @Override
    public boolean book(final Date date) {
        return agenda.isBookable(date);
    }
}
----

== Using Application Composer

Now, that the application is completed, it's time to test it. For this, we will add a unit test that will use Application Composer to start and deploy our application in a full JEE environment.
The full test:

[source,java]
----
import org.apache.openejb.jee.WebApp;
import org.apache.openejb.junit.ApplicationComposer;
import org.apache.openejb.testing.Classes;
import org.apache.openejb.testing.Configuration;
import org.apache.openejb.testing.EnableServices;
import org.apache.openejb.testing.Module;
import org.apache.openejb.testng.PropertiesBuilder;
import org.apache.openejb.util.NetworkUtil;
import org.junit.Test;
import org.junit.runner.RunWith;

import javax.xml.bind.JAXBContext;
import javax.xml.namespace.QName;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
import java.net.URL;
import java.util.Date;
import java.util.Properties;

import static org.junit.Assert.assertTrue;

@EnableServices("jax-ws")
@RunWith(ApplicationComposer.class)
public class MeetingPlannerTest {
    private static final int JAX_WS_PORT = NetworkUtil.getNextAvailablePort();

    @Configuration
    public Properties configuration() {
        return new PropertiesBuilder().p("httpejbd.port", Integer.toString(JAX_WS_PORT)).build();
    }

    @Module
    @Classes(cdi = true, value = {MeetingPlannerImpl.class, LazyAgenda.class})
    public WebApp war() {
        return new WebApp()
                .contextRoot("/demo")
                .addServlet("jaxws", MeetingPlannerImpl.class.getName(), "/meeting-planner");
    }

    @Test
    public void bookPort() throws Exception {
        final Service service = Service.create(
                new URL("http://127.0.0.1:" + JAX_WS_PORT + "/demo/meeting-planner?wsdl"),
                new QName("http://jaxws.example.superbiz.org/", "MeetingPlannerImplService"));
        final MeetingPlanner planner = service.getPort(MeetingPlanner.class);
        assertTrue(planner.book(new Date(System.currentTimeMillis() + 1000000)));
    }
}
----

First thing to see, we use Application Composer as a JUnit runner. So, our test integrates with current tools just like any other JUnit test. The test's configuration is defined in the method annotated with `@Configuration`.

The application is started in the method having the `@Module` annotation. In this example, we specify the classes we want to scan, and the fact that we want to use CDI.

Our test makes a booking request, sending a date in the future, then it verifies that booking is done.

== Running the test

Running the test we can see that the application was successfully started, that the JAX-WS service is running and that it fulfills incoming requests correctly.
