The program violates the Enterprise JavaBeans (EJB)
					specification by using AWT/Swing.The Enterprise JavaBeans specification requires that every bean provider
						follow a set of programming guidelines designed to ensure that the bean will
						be portable and behave consistently in any EJB container. In this case, the
						program violates the following EJB guideline: "An enterprise bean must not
						use the AWT functionality to attempt to output information to a display, or
						to input information from a keyboard." The specification justifies this
						requirement in the following way: "Most servers do not allow direct
						interaction between an application program and a keyboard/display attached
						to the server system."
