when I studied 3-tier architecture, I was told that it takes three servers: 1- web server 2- application server 3- BD server By cons when I work in JEE, there is a single server that Glassfish or JBOS under which runs all the modules, My question is how does 3-tiers architecture appear JEE, is it necessary to extract the web module from multi-third party applications and put it specially on a web server, for example apache and leave the EJB on glassfish? enter image description here

Your diagram visualizes application and webcontainer separately but in case of application server, it contains itself web container/server. yes you can use only services which only rely on webserver instead of EJB. So if your specifically talking about java EE then Distributed Multitiered Applications and What is the difference between application server and web server?
helps you to understand.
