 <p>Application Composer é uma API para criar uma aplicação EE programaticamente. Ísto é muito útil em um contexto de texto, por isso não é de admirar que se originou a partir daqui.
 Para mais informação sobre o Application Composer, por favor acessar o link <a href="http://tomee.apache.org/tomee-8.0/docs/application-composer/index.html">Seção do Compositor de Aplicativos na documentação</a>.</p>
 </div>
 <div class="paragraph">
 <p>Neste exemplo, vamos usar o <code>@ApplicationComposer</code> no contexto de uma aplicação JAX-WS .</p>
 </div>
 </div>
 </div>
 <div class="sect1">
 <h2 id="_exemplo">Exemplo</h2>
 <div class="sectionbody">
 <div class="paragraph">
 <p>Este exemplo é uma aplicação de planejamento de reuniões. É um aplicativo JAX-WS e aceita requisições para a reserva de reuniões. A aplicação primeiro verifica se a requisão pode ser reservada, se possivel, ela é reservada e retorna para o cliente se o pedido foi reservado (um valor booleano). Esta é uma aplicação simples, com propósito de demonstração, por isso é bastante simplificado. Uma solicitação de reserva é representada apenas pela data de início da reunião (um valor <code>java.util.Date</code>).
 Uma solicitação de reserva pode ser reservada se começar após a data atual.</p>
 </div>
 <div class="paragraph">
 <p>A logica de negócio é implementada usando uma classe <code>MeetingPlannerImpl</code> (implementando` MeetingPlanner`). Esta classe é um serviço JAX-WS, expondo o seguinte método: <code>boolean book (final Date date)</code>.
 O cliente vai enviar uma requisição, contendo uma data; o serviço vai retornar true ou false, se o pedido pode ser reservado. O serviço JAX-WS exposto usa, além disso, uma característica diferente, CDI, injetar uma
 classe de serviço de lógica de negócios, verificando se a solicitação pode ser reservada. Então, quando chegar a hora de testar a anotação <code>@ ApplicationComposer</code>, verificaremos se o CDI funcionou em nossa aplicação e se o serviço JAX-WS está em execução (ou funcionando).</p>
 </div>
 <div class="paragraph">
 <p>A lógica de negócios que verifica se uma solicitação é registrável é definida pela seguinte interface:</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre class="highlight"><code class="language-java" data-lang="java">import java.util.Date;

 public interface Agenda {
     boolean isBookable(Date d);
 }</code></pre>
 </div>
 </div>
 <div class="paragraph">
 <p>A implementação é simples, sem muitos detalhes:</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre class="highlight"><code class="language-java" data-lang="java">import java.util.Date;

 public class LazyAgenda implements Agenda {
     @Override
     public boolean isBookable(final Date d) {
         return d.after(new Date());
     }
 }</code></pre>
 </div>
 </div>
 <div class="paragraph">
 <p>O serviço JAX-WS é definido pela seguinte interface:</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre class="highlight"><code class="language-java" data-lang="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);
 }</code></pre>
 </div>
 </div>
 <div class="paragraph">
 <p>A classe que implementa essa interface é:</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre class="highlight"><code class="language-java" data-lang="java">import javax.inject.Inject;

     private Agenda agenda;

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

 <p>A primeira coisa que podemos notar é que, nós usamos o  Application Composer como executor JUnit. Então, Nosso teste se integra com as ferramentas atuais, assim como qualquer outro teste JUnit. A configuração do teste é definida no método anotado com <code>@ Configuration</code>.</p>

 <p>A aplicação é iniciada no método tendo a annotatação <code>@Module</code> . Neste exemplo, especificamos as classes que queremos analisar e o fato de que queremos usar o CDI.</p>
