30. jsf and database connection problem

First of all, a warning: NEVER use MS-Access, MS-Foxpro or the jdbc/ODBC bridge for real-world webapps. It's OK for playing around, but the two databases in question aren't capable of handling multi-user workloads and you'll end up with corrupted databases in short order. There's no special magic in doing database access using JSF. The only real trick is that if you ...

Unfortunately not. It depends on whether the transactions are equally spread throughout the day or have "peak" and "off" times, how long it takes that best- and worst-case times to execute the transactions, and other things, including whose webapp server you'll be running. Obviously that many transactions per day indicates a lot of activity, so you'll almost certainly want a clustered ...

57. Database Schema Updates

This isn't JSF specific, incidentally. If you're going to dynamically modify the schema from within a webapp, probably the best way to do it is to have a servlet that runs the mods in its init() method and setup web.xml so that that servlet runs first, before any other servlets. That way no one will attempt to access the database while ...

You cannot (usually) make an EJB/JPB Domain Model Object be a JSF backing bean because - while it's technically possible - they operate in different ways.
