How to Run Java Servlets
Java Servlets refer to Java programming language objects that are used to take requests from users or other computer systems dynamically and send appropriate responses. The Java Servlet Applied Programming Interface is used by developers to create dynamic web-based content from the server. Java Servlets can be used to create content based on discreet data saved in XML or text format.
