All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`destroy()`
`protected void`	`doGet(HttpServletRequest request, HttpServletResponse response)`	This is the main dispatch method for the servlet.
`protected void`	`doPost(HttpServletRequest request, HttpServletResponse response)`	Since this is a toy, we don't really care whether they call get or post.
`protected Teller`	`getTeller()`	This helper method will return a Teller in development based on a JNDI lookup.
`void`	`init()`	Init verify the teller reference to the EJB logic is in place and initializes the proper handler for the assigned role supplied in the servlet init parameters.
