+<h1>Comparison</h1>
+</div>
+
+<p>EJB as a technology has been historically misunderstood. Many people do not realize, for example, that EJB is only a tiny bit smaller than Java EE itself.</p>
+
+<p>Due to the many things integrated with EJB, the API effectively pulls in nearly all the Java EE APIs.</p>
+
+<p>It is impossible to implement "just" an EJB container and there really is no such thing as "just EJB".</p>
+
+<h1>The EJB "Profile"</h1>
+
+<p>There is no such thing as the "EJB Profile" in Java EE, but in many ways that's exactly what EJB is; a profile like the Web Profile or the Full Profile.</p>
+
+<p>Some concrete examples of how EJB is really just a "profile" of Java EE.</p>
+
+<ul>
+<li>JTA and EXTENDED JPA EntityManagers are created and managed by the EJB Container</li>
+<li>Message-Driven Beans (MDBs) require support for the Java EE Connector Architecture and the Java Message Service (JMS)</li>
+<li>Stateless and Singleton beans can be exposed as JAX-WS and JAX-RS services</li>
+<li>All EJBs <em>are</em> CDI beans ... always</li>
+<li>Transactions (TransactionManager) and Security (JAAS & JACC) are basic services of any EJB</li>
+<li>Timers and Schedules require integration with things like Quartz</li>
+<li>The following resource can be injected into any EJB
+<ul>
+<li>Bean Validation <code>javax.validation.Validator</code> and <code>javax.validation.ValidatorFactory</code></li>
+<li>JavaMail <code>javax.mail.Session</code></li>
+<li>JMS <code>javax.jms.Topic</code>, <code>javax.jms.Queue</code> and <code>javax.jms.ConnectionFactory</code></li>
+<li>CORBA <code>org.omg.CORBA</code></li>
+<li>JAX-WS WebService endpoints</li>
+<li>JTA <code>javax.transaction.UserTransaction</code></li>
+<li>CDI <code>javax.enterprise.inject.spi.BeanManager</code></li>
+</ul></li>
+</ul>
+
+<p>When you break apart "E" "J" and "B", what it means is the seamless integration of the following technologies:</p>
+
+<ul>
+<li>Java Transaction API (JTA)</li>
+<li>Java Persistence API (JPA)</li>
+<li>Java API for XML Web Services (JAX-WS)</li>
+<li>Java API for RESTful Web Services (JAX-RS)</li>
+<li>Java Messaging Service (JMS)</li>
+<li>Java Contexts and Dependency Injection (CDI)</li>
+<li>Java EE Connector Architecture (inaccurately called JCA sometimes)</li>
+<li>Java Authentication and Authorization Service (JAAS)</li>
+<li>Java Authorization Contract for Containers (JACC)</li>
+<li>JavaMail API</li>
+<li>Bean Validation</li>
+</ul>
+
+<h1>Outside the EJB "profile"</h1>
+
+<p>So what is left out of the EJB "profile" ?</p>
+
+<ul>
+<li>Java Servlets</li>
+<li>Java ServerPages (JSP)</li>
+<li>Java ServerFaces (JSF)</li>
+</ul>
+
+<p>Why wasn't TomEE done as a separate project? Actually it effectively was, that other project is Tomcat. Tomcat and MyFaces to be exact.</p>
+
+<h1>How is OpenEJB different than TomEE?</h1>
+
+<p>It's different in two major ways, only one of them technical:</p>
+
+<ul>
+<li>TomEE incorporates two additional projects; Tomcat and MyFaces</li>
+<li>TomEE, as a name, more easily implies the breadth of technologies included</li>
+</ul>
+
+<p>Effectively, TomEE is a superset of OpenEJB.</p>
