Agree that we won't contain this in G 2.2, but it might be a candidate feature for futher release like JEE6 Web Profile.
Importing Tomcat server configs is relatively easier than importing Tomcat applications.

Still, doable, but not a trivial work. -Jack 2009/5/20 Ivan <xhh...@gmail.com> > I guess that what David means is that writing a deployer for server.xml, > then in the builder class, construct those tomcat server gbeans, and add > those gbeans to the tomcat plugin section in the config.xml.
