Does Tomcat support Servlets 2.5?

[Jeffrey Tian]

I just started to learn the book Head First Servlets and JSP. This book is using Servlets 2.5.
Do I have to install Tomcat 5 or 6 for this book?

Thanks,

Actually, the question should be more of "Should I install Tomcat 7 or 8?"

Tomcat 5 has passed End of Life and is no longer actively supported by Apache. Tomcat 6 is aging and won't be supported much longer, as Tomcat 9 is in the works.

For the most part, any newer Tomcat will support webapps designed to run under older Tomcat versions. Most information on configuration of Tomcat itself is still applicable for any Tomcat release of 5.5 or later. Tomcat 7 did introduce a new database connection pooler, but its basic configuration is similar to the older DBCP pooler used by previous releases.

And, of course, we do have a Tomcat-specific forum in case you need help!
