Servlet architecture comes under a java programming language used to create dynamic web applications. Mainly servlets are used to develop server-side applications. Servlets are very robust and scalable. Before introducing servlets, CGI (common gateway interface) was used.
Frameworks are large prewritten code to which you add your own code to solve a problem in a specific domain.
You make use of a framework by calling its methods,inheritance,and supplying “call-backs” listeners.
Spring is the most popular application development framework for enterprise Java™.
Millions of developers use Spring to create high performing, easily testable, reusable code without any lock-in.

J2EE : Java servlet and its types, environmentjoearunraja2
The server-side extensions are nothing but the technologies that are used to create dynamic Web pages. Actually, to provide the facility of dynamic Web pages, Web pages need a container or Web server. To meet this requirement, independent Web server providers offer some proprietary solutions in the form of APIs (Application Programming Interface).
These APIs allow us to build programs that can run with a Web server. In this case, Java Servlet is also one of the component APIs of Java Platform Enterprise Edition (nowadays known as – ‘Jakarta EE’) which sets standards for creating dynamic Web applications in Java.
Today we all are aware of the need to create dynamic web pages i.e. the ones that can change the site contents according to the time or can generate the content according to the request received by the client. If you like coding in Java, then you will be happy to know that using Java there also exists a way to generate dynamic web pages and that way is Java Servlet. But before we move forward with our topic let’s first understand the need for server-side extensions.
Servlets are the Java programs that run on the Java-enabled web server or application server. They are used to handle the request obtained from the web server, process the request, produce the response, and then send a response back to the web server. Servlet is faster than CGI as it doesn’t involve the creation of a new process for every new request received.
Servlets, as written in Java, are platform independent.
Removes the overhead of creating a new process for each request as Servlet doesn’t run in a separate process. There is only a single instance that handles all requests concurrently. This also saves the memory and allows a Servlet to easily manage the client state.
It is a server-side component, so Servlet inherits the security provided by the Web server.
The API designed for Java Servlet automatically acquires the advantages of the Java platforms such as platform-independent and portability. In addition, it obviously can use the wide range of APIs created on Java platforms such as JDBC to access the database.
Many Web servers that are suitable for personal use or low-traffic websites are offered for free or at extremely cheap costs eg. Java servlet. However, the majority of commercial-grade Web servers are rather expensive, with the notable exception of Apache, which is free.
The Servlet Container
Servlet container, also known as Servlet engine, is an integrated set of objects that provide a run time environment for Java Servlet components. In simple words, it is a system that manages Java Servlet components on top of the Web server to handle the Web client requests.
Services provided by the Servlet container:
Network Services: Loads a Servlet class. The loading may be from a local file system, a remote file system or other network services. The Servlet container provides the network services over which the request and response are sent.

Servlets are part of the Java2EE specification.
Servlets are modules that run on the server,
enabling you to extend the server’s functionality.
Servlets work within a Web server environment,
and they are a key component of server side
Java development. Servlets are an effective
replacement for CGI scripts.
3.
Can be deployed into distributed server
environments.
Servlets are platform- and server-independent.
Servlets are easy to develop and follow a
standard API.
Servlets are extensible. Java Server Pages (JSP)
build on top of the Servlet API.
A servlet is a server resource, providing access to
other server resources, such as other servlets,
EJBs, JSPs, JDBC, and so on.
4. Method
Description
GET
The client requests information from the given
URL.
HEAD
Similar to GET, except the body is not retrieved.
POST
Client adds info to URI (HTML forms)
PUT
Used to place documents on the Server.
DELETE
Client deletes resource of URI.
6.
The Servlet API defines a standard interface for
handling request and response between the
browser and the Web server.
The Servlet API is composed of two packages:
javax.servlet - javax.servlet.GenericServlet
javax.servlet.http - javax.servlet.HttpServlet
9. Can use ServletOutputStream or PrintWriter to send data
back to the client.
1. reference the stream from the Response parameter:
ServletOutputStream out =response.getOutputStream();
2. get a reference to the writer from the Response
parameter:
PrintWriter out = response.getWriter();
3. Then write the output to the stream:
out.println(“<HTML>Inside HTML</HTML>”);
4. Finally, close the writer:
out.close();
10.
MIME – Multiple Internet Mail Extension
Identifies extension of each file in the
HTTPResponse
response.setContentType(“text/html”);
PrintWriter out = response.getWriter();
11. import java.io.*; import javax.servlet.*; import javax.servlet.http.*;
public class srvltJust extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse
res) throws ServletException, IOException {
res.setContentType(“text/html”);
PrintWriter out = res.getWriter();
out.println(“<HTML>”);
out.println(“<HEAD><TITLE>Servlet</TITLE></HEAD>”);
out.println(“<BODY>”);
out.println(“<H1>This is a just a Servlet!</H1>”);
out.println(“</BODY></HTML>”);
out.close();
12.
13.
14. Parameters
public String getParameter(String name)
public Enumeration getParameterNames()
public String[] getParameterValues(String name)
Content
public int getContentLength() - returns the length, in
bytes. -1 is returned if the length is not known.
getContentType() - returns the request’s MIME type
of the content (null if it’s not known).
getCharacterEncoding() - returns the name character
encoding style of the request.
19. API for persistent cookie is,
javax.servlet.http.Cookie
To create a new cookie,
Cookie cookie(String name, String value)
Eg: Cookie cookie = new Cookie("ID", "123");
To get all available cookies,
req.getCookies()
To send back the cookie name
response.addCookie(cookie_name)
20.
A servlet with getSession( ) method retrieves the current
HttpSession object
Eg: public HttpSession HttpServletRequest.getSession(boolean )
Set properties by,
public void HttpSession.setAttribute(String name, Object value)
Eg: session.setAttribute(“name”, id);
Get properties by,
public void HttpSession.setMaxInactiveInterval(int secs)
21.
Get current session id by,
public String getId()
Whether it is a new cookie or referenced,
public boolean isNew
Start of a session
public long getCreationTime()
Last session activity
public long getLastAccessedTime
Session invalidating by,
public void invalidate()
Removing attribute by,
public void removeAttribute(String name)
