Servlets are server side programs that respond to requests from browsers. They run in the Web environment. Portal technology grew from the servlets, and each portal page ends up as a servlet. Servlet technology is the foundation of Web application development using the Java programming language. ...

The Java code,HelloWorld.javabelongs in $app-dir/WEB-INF/classes/test/HelloWorld.java Or, if you're compiling the servlet yourself, the class file belongs in $app-dir/WEB-INF/classes/test/HelloWorld.class Following is the actual servlet code. It just prints a trivial HTML page filled with...
Servlets provide a component-based, platform-independent method for building web-based applications, without the performance overheads, process limitations, and platform-specific liabilities of CGI programs. Servlets supported by the Sun Java System Web Server are based on the Java Servlet 2.3 specificati...
drawback is that CGI programs tend to be platform dependent. A CGI programwritten for one operating system may not run on another. Sun’s Java Servlet platform directly addresses the two main drawbacks of CGI programs.First, servlets offer better performance and utilization of resources than...
The FirstServlet class imports the necessary classes for compiling a basic servlet, which are the emphasized import statements in Example 1-1. The Java class extends HttpServlet. The only defined methods are doGet( ) , which displays the HTML form in response to a GET HTTP request, and doPo...
Java is platform independent, while CGI can be platform independent scripts (Perl scripts) or platform dependent (compiled C programs) Servlet module would be loaded once when the first time it is invoked; stays loaded until the HTTP server task is shut down or restarted. CGI script is loaded...
