I am going to use Tomcat as my webapp container. The Resin will be left. As I found there is a bug in combining Resin with Apache, and there is no other special features in Resin but Axis is another Jarkarta project which is much steady when embed with Tomcat. And more and more people use Tomcat as a development tool. In all it's time to change Web App Server.

Tomcat, I am coming...
