I worked with server-side Java 3 years ago, and I used J2SE 1.4 together with Tomcat 4 (with Servlets 2.3 and JSP 1.2) to build commercial websites. I am planning on using server-side Java again, and I currently have J2SE 1.5 and Tomcat 5.5.4 (Servlets 2.4 and JSP 2.0). I read some people's opinions that J2SE is only good when you develop interfaces, while for server-side development J2EE 1.4 is necessary. However, Tomcat already provides me with Servlets and JSP functionality, and the J2SE+Tomcat configuration worked pretty well before, so I am not exactly clear on J2EE's advantages. Any advice will be appreciated.
