The functions of the Servlet container are as follows:
Lifecycle management : It manages the life and death of a servlet, such as class loading, instantiation, initialization, service, and making servlet instances eligible for garbage collection.
Communication support : It handles the communication between the servlet and the Web server.
Multithreading support : It automatically creates a new thread for every servlet request received. When the Servlet service() method completes, the thread dies.
Declarative security : It manages the security inside the XML deployment descriptor file.
JSP support : The container is responsible for converting JSPs to servlets and for maintaining them.
