hello, good day,

Are the Later versions of Tomcat (version 3.3 or higher) compatible with JSP 1.1 and Servlets 2.2 or is limited to Tomcat ver 3.3?
I've been searching this in the forums and Google for days, but no definite statement regarding this concern. Any help would be greatly appreciated.
thanks!

Hi, that's one of the pages Ive been reading since, but it doesn't state explicitly whether the higher versions are backward compatible.

I don't know. This page says "With very few exceptions, Servlet 2.3 web applications should work fine in a Servlet 2.4 container.".
The servlet spec says "For backwards compatibility of applications written to the 2.2 version of the API, Web containers are also required to support the 2.2 version of the deployment descriptor. For backwards compatibility of applications written to the 2.3 version of the API, Web containers are also required to support the 2.3 version of the deployment descriptor. The 2.2 and 2.3 versions are defined in the appendices."
If Tomcat is fully spec complient, it should be ok. But is it really ? JSP, I'm not sure. If you are trying to upgrade to a new container, you'd have to test everything anyway.

yup! I'm actually somewhat more confident with regard to backward compatibility of Servlets now. JSP on the other hand, I was able to find out that JSP 2.0 is fully backward compatible with JSP 1.2, but I haven't found any luck yet about JSP 1.1.
