/**
 * Bind the resource manager instance to the JNDI directory.

 * This method will use the full JNDI path provided for the resource
 * manager, and will create if necessary the individual segments of that
 * path.
 * 
 * @param jndiName
 *            The full JNDI path at which the resource manager instance will
 *            be bound in the JNDI directory. JNDI clients can use that path
 *            to obtain the resource manager instance.
 * @param obj
 *            The object to be bound.
 * @return <b>true</b> if the resource manager was successfully bound to
 *         JNDI using the provided path; otherwise <b>false</b>.
