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 : Generic Servlets HTTP Servlets

8. P otential W ays There are three potential ways in which we can employ to create a servlet : Implementing Servlet Interface Extending Generic Servlet Extending HTTP Servlet

10. D emonstrate Servlet 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 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.
