Tomcat Interview Questions and Answers

Question: Explain the concepts of Tomcat Servlet Container.

• A servlet container is a specialized web server that supports servlet execution.
• It combines the basic functionality of a web server with certain Java/servlet specific optimizations and extensions (such as an integrated Java runtime environment, and the ability to automatically translate specific URLs into servlet requests).
• Individual servlets are registered with a servlet container, providing the container with information such as the functionality, the URL used for identification.
• The servlet container then initializes the servlet as necessary and delivers requests to the servlet as they arrive.
• Many containers can dynamically add and remove servlets from the system, allowing new servlets to quickly be deployed or removed without affecting other servlets running from the same container.
• Servlet containers are also referred to as web containers or web engines.
