A Servlets skeleton would look like below:
/*
* servlet name
*
* servlet description
* All other stuff that is part of a Standard Class comment section
*/
//package declarations
//import statements
public class ServletName extends HttpServlet {
// Instance Variables
/**
* Code to Initialize the Servlet
*/
public void init() throws ServletException
{
// Servlet Initialization Code goes here
}
/**
* The Service Method
* Gets invoked for every request submitted to the Servlet
* This method is optional. We mostly use doGet, doPost Methods
*/
protected void service(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, IOException
{
// Code for the Service Method goes here
}
/**
* Process a GET request
*
*/
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
// Code for the doGet() method goes here
}
/**
* Process a POST request
*
*/
protected void doPost(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
// Code for the doPost() method goes here
}
/**
* Process a PUT request
*
*/
protected void doPut(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, IOException
{
//Code for the doPut() method goes here
}
/**
* You can have any number of methods for your processing
* here. There is no limit as to the number of methods or
* any restrictions on what you can name them.
* Since this is all java code, you need to keep them
* syntactically correct as per Java Coding Standards.
*/
/**
* Clean-Up
*/
public void destroy()
{
// clean up activities before the Servlet is put to death
}

Medical anatomy is very detailed. Paramedical anatomy is general.
The two major groups which the topics of anatomy lie are Gross anatomy & Microscopic anatomy
yes it is
The Anatomy of Peace was created in 1946.
Organ physiology is to cell physiology as gross anatomy is to microscopic anatomy
Java Servlet is used for Server Side programming for developing Web Applications. It easily employs Database Connectivity. We can also use JSP however it cannot replace a Java Servlet.
Java Applet is an application designed to transmit on internet to execute on java compatible browsers. Java Servlet is a server side program used to provide services to clients.
Networking is a basic action. A servlet in Java is a single part of networking, a single task.
Yes you can but it is not required. A Servlet is nothing but another .java file and all rules that are applicable to standard Java classes are applicable to them. Note: Even if you write a constructor in a servlet, it will not get executed.
No. Javascript code can be present inside a JSP but not inside a servlet. A Servlet is a pure java class.
Tomcat is a server. It is used to deploy and run Servlets and not compile them. A Servlet is a java file and has to be compiled just like any other Java Class.
You cannot. HTML is a static file and it cannot interact with a Java Servlet. A Servlet can always redirect to a HTML page but the other way round cannot happen.
Advance java is the implementation of servlet in web pages.
Java Servlet Development Kit is an integrated development kit used to build, test, and deploy Java Servlet applications. JSDK allows most standard Web server such as Netscape servers, IIS, Apache and others to load servlets . JSDK is a suite of software for easing the development of Java servlets.
Perl, php and Java are all examples of programming languages.
Because it is not a regular Java Class that is executed by a JVM. It is a special Java class that is executed by the Web Container which initializes and loads the servlet and the service methods get executed everytime it receives a request.
(This is a bit subjective). Servlets can integrate easily into an existing Java application or applet, simply because a servlet is just another class, which is a fundamental concept taught to almost every java programmer.
