What is Web Container in Java?
Web Container is an java application that
controls servlet. Servlet do not have a main() method, So they require a
container to load them. Container is a place where servlet gets deployed.
When a client sends a request to web server
that contain a servlet, server sends that request to container rather than to
servlet directly. Container then finds out the requested servlet and pass the
Http Request and response to servlet and loads the servlet methods i.e. doGet()
or do Post().
Example of a web container is Tomcat.
