Can anybody tell me the difference between Tomcat(Servlet/JSP engine), Apache (a web server) and an application server(Websphere, JBoss). Which one to use, when and why?. Why do you need apache if tomcat can do the stuff for you. Also does tomcat 5.0 come with an webserver(apache) built-in?.
Also if u could point to any article u know of which is good with these basics, that would be great.
Apache: all purpose open source web server written in C Tomcat: open source web server written in Java. Mostly used for small projects. Websphere: This is the application server from IBM for large projects, like banking applications JBoss: Open source application server
Basically a web server is meant for the web and an application server for ehm applications. Tomcat can be used as standalone web server, but if you want better security you should link it with Apache.
