The Servlet lifecycle consists of the following steps:The Servlet class is loaded by the container during start-up. The container calls the init method. This method initializes the servlet and must be called before the servlet can service any requests. In the entire life of a servlet, the init method is called only once. After initialization, the servlet can service client-requests. Each request

hi thereJava Servlets are small programs coded in the Java programming laguage that are executed on a web server. They perform certain task and are able to produce dynamic web content, ie generate web pages on-the-fly.The Java Servlet API allows a software developer to add dynamic content to a Web server using the Java platform. The generated content is commonly HTML, but may be other data

A JSP page services requests as a servlet. Thus, the life cycle and many of the capabilities of JSP pages in particular the dynamic aspects are determined by Java Servlet technology. 1. JSP page container first checks whether the JSP pages servlet is older than the JSP page. If the servlet is older, the web container translates the JSP page into a servlet class and compiles the class. During

A servlet is a small program that runs on a server. The term was coined in the context of the Java applet, a small program that is sent as a separate file along with a Web HTML page. Java applets be implemented with the Java programming language. The advantage of a Java servlet on servers with lots of traffic is that they can execute more quickly than CGI applications. Rather than causing a separate

In the beginning, servlets were invented, and the world saw that they were good. Dynamic web pages based on servlets executed quickly, could be moved between servers easily, and integrated well with back-end data sources. Servlets became widely accepted as a premiere platform for server-side web development.However, the commonly-used simple approach to generating HTML content, having the programer

at the server end through CGI scripts, server side applications, and now servlets!Servlets are pieces of Java code that work at the server end. Servlets have all the access to resources on the server that a CGI script do, and arent normally limited by the restrictions on file and network access that Java applets have traditionally been held back by. Servlets also offer substantial performance advantages
