Answer 1

WebLogic, JBOSS, and other Java EE app servers have servlet containers, plus more: EJBs, naming and directory service, JMS, etc.

Servlets are HTTP listeners that run inside a servlet container. The servlet can be mapped to response to HTTP GET and POST requests to a given URL of your choice. The container manages the lifecycle and pooling of the servlets.
