The document discusses the servlet architecture in Java, highlighting its role in creating dynamic web applications and server-side applications. It covers the types of servlets, methods for creating them, and their lifecycle from initialization to destruction. Servlets are noted for their robust nature, scalability, and ability to manage application flow efficiently.

2. Servlet Architecture
• Servlets are grouped under the
Advanced Java tree that are used to create
dynamic web applications. Servlets are robust
in nature, well scalable and are primarily used
in developing server-side applications.

3. Servlet Architecture
• If we go a little back in time, we
would be able to witness that before the
introduction of servlets.
• CGI (Common Gateway Interface) were used.

4. Servlet Architecture
• Amid several indigenous tasks that
a servlet is capable of doing, dynamically
performing client requests and responses are
most common.
• Other tasks that a servlet can do effectively are

5. TASKS
• Can easily manage/control the
application flow.
• Suitable to implement business logic.

6. TASKS
• Can effectively balance the load
at the server-side.
• Easily generate dynamic web
content.

7. TYPES
• Talking about the types of servlets,
there are primarily two types, namely:
1. Generic Servlets
2. HTTP Servlets

8. Potential Ways
• There are three potential ways in which
we can employ to create a servlet:
Implementing Servlet Interface
Extending Generic Servlet
Extending HTTP Servlet

9. Servlet Architecture
• Servlet architecture comes under
a java programming language used to
create dynamic web applications.
• Mainly servlets are used to develop
server-side applications.

10. Demonstrate Servlet
o What are Servlets demonstrate Servlet
architecture and explain its working?
• Servlets execute within the address
space of a Web server.
• It is not necessary to create a separate
process to handle each client request.

11. Demonstrate Servlet
• Servlets are platform-independent
because they are written in Java.
• Java security manager on the server
enforces a set of restrictions to protect the
resources on a server machine.

12. Life cycle with Architecture
o What is Servlet ,Servlet lifecycle with
architecture?
Advertisements.
A servlet life cycle can be defined as the
entire process from its creation till the
destruction.

13. Methods
• The following are the paths followed by a
servlet.
• The servlet is initialized by calling the init()
method.
• The servlet calls service() method to process a
client's request.
