 * This is an interface for Container plugins. Implementations of this

 * and to forward these requests to the Container it is being used with.
 *
 * <p>It is responsible for providing any EJBObject and EJBHome 
 *    implementations (which may be statically or dynamically created). 
 *
 * <p>Before forwarding a call to the container it must call
 *    Thread.setContextClassLoader() with the classloader of the container.
 *    It must also handle any propagated transaction and security contexts
 *    properly. It may acquire the TransactionManager from JNDI.
