Question

tomcat apache? what is the difference? need a clear picture

Asked by: gagaliya

Hello, i recently signed up with a hosting plan that gave me root access to my vpn type account. So now am trying to figure out this tomcat apache deal.  I am pretty knowledgable in general about using web servers (use weblogic professionally at work) but have little to no experience when it comes to open source tomcat/apache. Please help with the following questions, thanks!

1) What is the difference between tomcat and apache and why do people use them together/interchangeably. Are they two separate servers? why do you need both to run a j2ee app?

For example for weblogic it's very clearly defined, you have a wls server you put your servlet/jsp on it and you start/stop the server and deploy.  So for tomcat/apache do i need to stop both, then start both for a reboot? my main question is what is the clear difference between the two?

2) Where usually are tomcat/apache located on the server?  is it two different directories one for tomcat and one for apache? In weblogic, usually you just goto ~/wls81/bin  then there is start-wl.sh and stop-wl.sh to start/stop server. And to deploy you just dump the jar/war file in the directory. How do i do that with tomcat/apache? where exactly do i put my je22 web package?  Bact to 1) should i deploy on tomcat, or apache, or both?

thanks for your time.

Found some more answers. are the answers correct can someone answer the last question the user asked?

Question  What is the difference between apache webserver, java webserver and tomcat server?  

Answer
Apache is an HTTP server written in C that can be compiled and run on many platforms. See http://www.apache.org

Java WebServer is an HTTP server from Sun written in Java that also supports Servlets and JSP.

Tomcat is an open-source HTTP server from the Apache Foundation, written in Java, that supports Servlets and JSP. It can also be used as a "plug-in" to native-code HTTP servers, such as Apache Web Server and IIS, to provide support for Servlets (while still serving normal HTTP requests from the primary, native-code web server). See http://jakarta.apache.org/tomcat
-------------------
if tomcat is both an http server and a servelet container, why is apache necessary in projects where tomcat is used ? Thx,

Apache is a web server (mainly support static html). Tomcat is a servlet container (mainly support servlets)

Can we maintain every thing (static html , JSP and servlets) with tomcat itself?. When do we need both Apache and Tomcat running on the server. Thank You

You found most answers yourself. Tomcat is used for serving dynamic content, using JSP and servlets. It can serve static pages as well. It depends on the balance between static vs dynamic content whether you need Apache HTTPD. If you're serving many static pages, you might want to use httpd as well because httpd is faster and has a lower server load.

Furthermore, Apache httpd seems to be a bit more easy to configure, and if you want to use virtual hosts, or need load balancing, you might prefer httpd over tomcat alone. Tomcat can do this as well I believe, although I haven't tried it out myself.

So you can do everything with Tomcat, but it's generally not preferred when serving static content.

in other words, apache is the webserver while tomcat is the application server. IMHO

(rpm command is banned from my hosting provider). is there a tar file somewhere i can downand and unzip?

Well I use Windows at work and a Mac at home, and both have binary installers, so I'm not really into installing on Linux. Try http://jakarta.apache.org/site/binindex.cgi and there you'll find installation binaries, like this one; http://apache.pagefault.net/jakarta/tomcat-4/v4.1.31/bin/jakarta-tomcat-4.1.31.tar.gz. Look there for the version you need, but I don't know if this is RPM or not. Maybe it's sourcecode that needs to be compiled.
