The short answer is "Both".

Tomcat is a servlet container that can also be run as a standalone webserver.

The distinctions between these terms is a bit blurry but here is
a rough description.
  • Appserver: Java term for an application that runs J2EE applications.

  • This includes EJB, Servlets, JNDI, JSP, and more..
  • Servlet Container: The part of an appserver that handles Servlets (most have JSP compilers built in With some, you have to pay more for this).
  • Webserver: An application running on a machine that handles HTTP requests.

  • Originally, these only handled static files and maybe CGI scripts.


    Tomcat can either be bound to an external webserver (such as Apache HTTPD or Microsoft IIS) but can also run as a stand-alone Webserver/Servlet container/JSP engine. It can also be embedded into a full Appserver such as JBoss.

    I think it only qualifies as a web container. Here you can find more info about a web container. Web Container

    You can certainly call it a web container. But that doesn't mean you cannot call it anything else; the terms are not precisely defined.

    It is sorta covered in the JavaRanch Style Guide.
