Just a couple of notes that might be useful to add to Part 7 (Developers Guide) of the Sculptor Docco in the section titled Deployment in Tomcat.
a) I was able to generate war and run in tomcat doing crud updates etc without any need for step #3 (inclusion of JTA). Maybe I'm missing the point re why JTA may be needed??
b) Having not used HSQLDB before I was unaware that hsqldb.jar needed also be copied into tomcat/lib/ to make the driver accessible. Basic stuff but a note re that would maybe save some time for newcomers
