JAVA PROGRAM

APPLICATION APPLET

STAND-ALONE DISTRIBUTED

1) Java application is further divided into two parts:

a) Stand-alone:- In it, we can access the resource

localy and we can’t share the resources as the system

is not available on the network.

b) Distributed:- In it, we can access the resources

within a limited area.

2) An applet is a java program which is used to access

the resources remotely .To execute an applet we need

a software WEB-BROWSER so that we can interact

with a network over a communication path.

JAVA SERVLETS

A servlet acts as an intermediary between the client and the server.

As servlet modules run on the server, they can receive and respond to requests made by the client.

Servlets are generally used to create Dynamic HTML pages .

9

JAVA SERVER PAGES Servlets and JSP both are complimentary API’s both

providing a means of generating dynamic web client .

JSP contains a mixture of HTML , JAVA-Script , Jsp Elements .

JSP is the easiest way to write Servlet .

Jsp pages are translated into servlets ,then servlets are compiled and at request time this compiled Servlet is executed.
