  /**
   * A template pattern implementation of the deploy() method. This method calls the {@link
   * #performDeploy(WebApplication, String, WebDescriptorParser) performDeploy()} method to perform
   * the container specific deployment steps and registers the returned WebApplication in the
   * deployment map. The steps performed are:
   *
   * <p>ClassLoader appClassLoader = thread.getContextClassLoader(); URLClassLoader warLoader =
   * URLClassLoader.newInstance(empty, appClassLoader); thread.setContextClassLoader(warLoader);
   * WebDescriptorParser webAppParser = ...; WebMetaData metaData = di.metaData; // Create JACC
   * permissions, contextID, etc. ... WebApplication warInfo = new WebApplication(metaData);
   * performDeploy(warInfo, warUrl, webAppParser); deploymentMap.put(warUrl, warInfo);
   * thread.setContextClassLoader(appClassLoader);
   *
   * <p>The subclass performDeploy() implementation needs to invoke processEnc(loader, warInfo) to
   * have the JNDI java:comp/env namespace setup before any web app component can access this
   * namespace.
   *
   * <p>Also, an MBean for each servlet deployed should be created and its JMX ObjectName placed
   * into the DeploymentInfo.mbeans list so that the JSR77 layer can create the approriate model
   * view. The servlet MBean needs to provide access to the min, max and total time in milliseconds.
   * Expose this information via MinServiceTime, MaxServiceTime and TotalServiceTime attributes to
   * integrate seemlessly with the JSR77 factory layer.
   *
   * @param unit The deployment info that contains the context-root element value from the J2EE
   *     application/module/web application.xml descriptor. This may be null if war was is not being
   *     deployed as part of an enterprise application. It also contains the URL of the web
   *     application war.
