I have a Seam application running in tomcat 5.1.17. In order to get Seam running in Tomcat the key is to deploy EJB Embedded microcontainer into Tomcat. If you can see in the booking example, when the application (.war) is deployed, you can have a look the mc-conf.jar (among other ejb jars), which is the key in order to have EJB applications deployed in Tomcat.
