[undertow-dev] How to Access ServletContext?

[Ari King]

A synopsis of how I'm setting up Resteasy follows, but for
convenience/reference I posted the entire relevant code here:
http://pastebin.com/JYMP22h2

I'm setting up Resteasy by leveraging
org.jboss.resteasy.spi.ResteasyDeployment and
org.jboss.resteasy.plugins.server.servlet.HttpServlet30Dispatcher.

Essentially, I create a new instance of "ResteasyDeployment" and set an
"Application" class for the deployment.

        ResteasyDeployment deployment = new ResteasyDeployment();
        deployment.setApplicationClass(appClass.getName());

Then I configure the servlet:

        ServletInfo servletInfo = Servlets.servlet("ResteasyServlet",
HttpServlet30Dispatcher.class)
                                          .setAsyncSupported(true)
                                          .setLoadOnStartup(1)
                                          .addMapping(appPath);

I create a new DeploymentInfo instance and set a few properties:

new DeploymentInfo().setClassLoader(Server.class.getClassLoader())
                                   .setContextPath("/")

.addServletContextAttribute(ResteasyDeployment.class.getName(), deployment)
                                   .addServlet(servletInfo)
                                   .setDeploymentName("api.example")

.addListeners(Servlets.listener(GuiceContextListener.class));

Then I add the deployment info to a container instance:

private final ServletContainer container =
ServletContainer.Factory.newInstance();
DeploymentManager manager = container.addDeployment(deployInfo);
manager.deploy();

Lastly, I set the undertow handlers, build, and start:

undertow = builder.setHandler(root).build();
undertow.start();

Thanks.
