1. Are you scaffolding from a MySQL database? If yes, then did you add the MySQL driver jar to the project? Please add the jar to the project’s WEB-INF/lib, and redeploy the project.
2. If the above doesn’t work, does the project work if you select the Derby database for scaffold as outlined in the example?
3. With MySQL, do you see any errors reported in the project post scaffolding?
4. Please share the zipped project to help us replicate the issue at our end. Also share the MyEclipse version details from Help > About MyEclipse dialog.
