Based on Hotel Booking example, I have provided another example Project. Main features as follows: 1. replace JSF with ExtJS 2.0. 2. Facade/Servlet + Service layer design. 3. Complete TestNG unit test of Service layer. You can download the war file http://seamextsample.googlecode.com/files/seamextsample-1.0-beta1.rar, and run it in Tomcat 5.x without any further configuration. JBoss Seam is great. I am happy to use it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4108534#...
