Servlet meaning
A Java application in a Web or application server that provides server-side processing such as e-commerce and database search. Servlets are designed to handle HTTP requests (get, post, etc.) and are the Java replacement for a variety of methods, including CGI scripts, Active Server Pages (ASPs) and proprietary C/C++ plug-ins for specific Web servers (ISAPI, NSAPI).Because they are written in Java, servlets are portable between servers and operating systems. The servlet programming interface (Java Servlet API) is a standard part of the Java EE platform. If a Web server does not run servlets natively, a third-party servlet plug-in can be installed to add the runtime support. See servlet container, Java, application server, JSP, Java EE, ISAPI, NSAPI and CGI script.
