The elements in a Java Server Page will generally be compiled by the JSP engine into a servlet, but the JSP specification only requires that the JSP page execution entity follow the Servlet Protocol. The advantage of Java Server Pages is that they are document-centric. Servlets, on the other hand, look and act like programs. A Java Server Page can contain Java program fragments that instantiate and execute Java classes, but these occur inside an HTML template file and are primarily used to generate dynamic content. Some of the JSP functionality can be achieved on the client, using JavaScript.
Delta Connection is a regional airline brand name for Delta Air Lines, under which a number of individually owned regional airlines operate short-and medium-haul routes. Delta's lone wholly owned regional airline, Endeavor Air, also resides under the Delta Connection banner.
Delta Air Lines as it exists today is the result of numerous mergers over its history. Predecessor carriers forming the current Delta Air Lines include: Chicago and Southern Air Lines (formed in 1933, merged into Delta in 1953). Delta flew under the carrier name of Delta-C&S for the following two years.
