I agree. Since the config file is so central to the application, and since there are so many ways to mess it up, detailed validation with specific, explanatory exceptions that show up on the browser's screen would be best. I thought about moving the connection to the top of the file, but came to the same conclusion you did that it would simply bury the error deeper in the application.

And in mi opionion the best would be not to start the application if the config file could'nt be parsed! Or give some usefull hint somewhere.
The problem with the documentation is that - if you write the connection
info first into your config file - the connection will be parsed correct and
the error will happen on another place. We have a lot of problems with
unparsable config files and error messages on other places.
So my suggestion is to do a check in the dbforms tag if dbforms is
initialized correct. If not then show an error page.
Best solution is if we can show the reason for the wrong initialization....
What do you think?

Hi
Never a rule without an exception to confirm the rule :) I am currently using DBForms with Oracle10g using the Oracle10g JDBC driver, and I have plenty of varchar2 columns defined in dbforms-config.xml - and it works :)
