JavaWebServer2.0 to Tomcat Question

I am using JavaWebServer2.0 and want to switch to Apache/Tomcat.
Question: Do I need both Apache Web Server and Tomcat or is Tomcat enough by itself?
Thanks.

Tomcat is enough.

Personally, I would give a more conservative answer, it depends. If you are trying to get started with servlets
(although, I wouldn't believe you) yes, Tomcat is enough.
However, if you are in the process of serving servlets etc
for a commercial purpose and with commercial support for
static html pages, then you might need apache.
Pl. note Apache supports static html pages and Tomcat supports
servlets, JSPs and html pages.

Also Apache supports CGI, in-process perl, PHP, htaccess authentication, URL rewriting, SSL and a whole load of other modules. Many people use Apache for all these things, and a plugin (Tomcat, Resin, JRun etc.) for servlets and JSPs.

another comment abt apache..."apache is a reference implementation on windows". All these goodies are
fully supported on Unix, but on windows there maybe
some surprises. Atleast thats' what I understand from
Apache documentation.
In short, your OS also matters to a certain extent.
Couldn't resist to say something negative....
