Custom DAOs
Hello,
I'm quite new to seam. I'm used to work with JBoss MBeans.
I generated a new project with seam-gen and now I try to build in a user query in the AuthenticatorBean to let login only people which are registered in the database. I used informations from that thread http://seamframework.org/Community/GenericDAOPatternWithSeammanagedTransactionsAndSMPCDoesntWork and now I'm getting the error
Caused by: java.lang.NoClassDefFoundError: RegisterAction
So the question is. Why is he missing RegisterAction and how can I fix it? Another question is Is this the right way to fetch the user table information from the mysql database?
Thx for your help
Ben
