Experimenting with spring dependency injection, servlet context and jersey. Servlet context (context initialized and context destroyed) is working, spring DI not yet working ,TODO...
Simple jersey example that loads Resources via JNDI (path to log4j.properties and spring.xml for Spring's FileSystemXmlApplicationContext, allowing to load deployment-specific beans for test/production deployments).

 - Added Spring dependency injection
 - Added an MBean to set up a JMX connection.
- Replaced old jersey implementation in pom with glassfish's implementation.
Added comment.
