This week's book giveaway is in the Design and Architecture forum. We're giving away four copies of Communication Patterns: A Guide for Developers and Architects and have Jacqui Read on-line! See this thread for details.
http://java.sun.com/j2ee/1.4/download.html contains many downloads. I am not sure which is the right one. Is it one listed against "Get the J2EE 1.4 SDK" or some other. Could you please verify that.
Also regarding Tomcat 5.5.27 which one needs to be downloaded. Is it the Core one under Binary Distributions.
Also it would be helpful if you could let me know any another thing that needs to be set like the classpath.
If you already have J2SE installed, you don't need it.
You need to get Tomcat's Core package. If you are using Windows, I recommend you to get the Windows Service Installer. It will set environment variables for you, and you will be able to start/stop the server from the task tray.
