This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
check out the "examples" directory in Seam distribution. Most examples can be built into Tomcat WARs.

You will need to setup your own data source for MySQL -- but that is covered in the app server manual.
