title: javax.faces.context.FacesContextFactory Exception while embedding Undertow with JSF application
body: <p>I am trying to build a simple JSF web application using embedded Undertow server.</p>
  
  <p>Gradle dependencies for the project:</p>
  
  <pre><code>dependencies {
  
                 compile group: 'io.undertow', name: 'undertow-core',    version: '1.4.0.CR3'
                 compile group: 'io.undertow', name: 'undertow-servlet', version: '1.4.0.CR3'
                 compile group: 'javax', name: 'javaee-api', version: '7.0'
                 compile group: 'org.glassfish', name: 'javax.faces', version: '2.2.11'
  
  }
  </code></pre>
  
  <p>Sample Undertow Server Code:</p>
  
  <pre><code>public class HelloWorldServer {
  
      public static void main(final String[] args) throws ServletException {
  
          DeploymentInfo servletContainer=Servlets.deployment()
                  .setClassLoader(HelloWorldServer.class.getClassLoader())
                  .setDeploymentName("helloWorld.war")
                  .setContextPath("")
                  .addServlet(Servlets.servlet("javax.faces.webapp.FacesServlet",FacesServlet.class)
                  .addMappings("/faces/*","/javax.faces.resource/*")
                  .setLoadOnStartup(1));
          DeploymentManager manager=Servlets.defaultContainer().addDeployment(servletContainer);
          manager.deploy();
          HttpHandler servletHandler=manager.start();
          PathHandler path = Handlers.path(Handlers.redirect(""))
                      .addPrefixPath("/", servletHandler);
  
           Undertow server = Undertow.builder()
                      .addHttpListener(8080, "localhost")
                      .setHandler(path)
                      .build();
              server.start();
  
      }
  }
