Log:
HORNETQ-149: Update JMS embedded example to actually start a JMSServerManager
* rewrote the emebedded example to use a JMSServerManager
* used JMSConfiguration API to configure the JMS server (see HORNETQ-161)

+ <h1>Embedded JMS Server Example</h1>
+
+ <p>This examples shows how to setup and run an embedded JMS server with HornetQ.</p>
+ <p>HornetQ was designed to use POJOs (Plain Old Java Objects) so that embedding HornetQ is as simple as instantiating a few objects.</p>
+ <p>This example does not use any configuration files. The server is configured using POJOs and can be easily ported to any dependency injection framework.<br />
+ We will setup and run a full-fledged JMS server which binds its JMS resources to JNDI and can be accessed by remote clients.</p>
- <p>HornetQ Embedded could be used from very simple use cases with only InVM support to very complex cases with clustering, persistence and fail over.</p>
- <br>
- <h2>Example step-by-step</h2>
- <p><i>To run the example, simply type <code>ant</code> from this directory</i></p>
- <p>In this we don't use any configuration files. (Everything is embedded). We simply instantiate ConfigurationImpl, HornetQServer, start it and operate on JMS regularly</p>
- <br>
- <ol>
- <li>Create the Configuration, and set the properties accordingly</li>
