I don’t know as to why that it has not yet occurred yet , — most likely I am forgotten anything. It might be nice to make use of RMI in place of bothering having rmic no matter if. – Peter

93. What is actually meant of the Servlet? Exactly what are the parameters of one’s solution approach ? A good Servlet try a coffees class one to stretches brand new request-reaction make of a keen webserver. they recieves demand off a client functions any neccessary procedures..makes a response object and sends it back again to the consumer.

There is no native password needed to processes tiny components, which management of lightweights is one hundred% implemented in common coffee code, which leads to complete texture all over programs.

The Lightweight parts is “lighter” because it takes zero indigenous analysis-structures or fellow kinds

62. Difference in App and Applet The difference between an application and you can a keen applet, is that an enthusiastic applet is utilized from inside the a web browser, and you may a credit card applicatoin, when you look at the a stand alone setting.
