You might be unaware of this but Maven is capable of running Tomcat 7 as embedded container. The maven-tomcat-plugin has been moved under the Apache Foundation umbrella and is being developed further. The current version is 2.0, packing in both versions of Tomcat, 6 and 7.
Setting it up is explained here. All the configuration is very similar to the original one and your IDE will help you out there (at least Eclipse does).
Finally... It's been way to long to wait for an update on this one.
