Apache and Tomcat confusion

Hi folks,

I need to install and application server software which requires to
install JAVA JRE 1.4 and Tomcat 5.0. My question is that Do i need to
install Tomcat even if I have Apache 2.0.52 server already installed on
that Redhat Linux 9.0 box?

Thanks,

Apache Tomcat is a "JSP Server". It serves and interprets Java Server
Pages. It requires Java *SDK* to operate. The Java Runtime Environment
(JRE) is not sufficient to successfully operate Tomcat. The reason is
that .jsp pages must be compiled to Java bytecode prior to execution in the
JVM. Without the SDK, there is no way to compile the .jsp files. BTW,
this is often why the first access of a jsp page is slower than subsequent
requests. You can get Tomcat to "precompile" some/all pages at server
start, but this delays server start - your choice; delay first access of
pages or delay server start.

Apache HTTP Server serves and interprets HTML pages. You can extend Apache
HTTP to interpret other things like PHP etc, but JSP is solely the domain
of Tomcat. There is a module to link Apache HTTP and Tomcat to basically
function like a single server, however they both retain their own config
files etc. The module basically handles whether a request should be
handled by Apache HTTP or Tomcat, then forwards it to the correct server
(process).

The connection between the two software packages is simply the Apache
Foundation. "Apache" (the Foundation) cover a number of projects including
a HTTP server (their first project, so usually Apache HTTP Server = Apache)
and Tomcat among others. Having an open source project annexed by the
Apache Foundation is seen by many as a great honour.

Don't confuse the two - hey are distinct and very different beasts :) Have
fun.

HTH,
