Class TomcatEmbedder

java.lang.Object
  org.apache.openejb.tomcat.loader.TomcatEmbedder

public class TomcatEmbedder
extends java.lang.Object

Ultimately this class does nothing lasting and just calls TomcatHook.hook(java.util.Properties) This class needs to know the path to the openejb.war file. With that information this class finds the openejb-loader jar in the openejb.war essentially creates a "mini-webapp" which is to say it creates a new WebappClassloader that contains the openejb-loader jar and then uses that classloader to reflectively call the TomcatHook.hook(java.util.Properties) method which does all the work to load OpenEJB into Tomcat This messing around is required so that it doesn't matter if the OpenEJBListener, which does not execute in a webapp classloader, or the LoaderServlet, which does, calls the TomcatEmbedder. Either way the embedding process starts inside a WebappClassloader and keeps that very complex code just a little simpler.
