That message occurs if the connection profile is not returning the proper generic properties for us to get the connection class/driver class etc.
Did you use the Generic connection profile ?
Please report the spelling error in jira.
Ok, I've been trying to reproduce this behaviour for the past 3 hours! I've managed to find the concrete circumstances of when this happens. It's weird:
What works: create a connection profile with correct settings. Start the seam project wizard and select that connection profile. No problem at all.
What is broken: edit an existing connection profile and make a change to its settings (e.g. the JDBC connection URL). Start the seam project wizard and you'll see that the "Driver Class" error occurs.
I'm filing bug reports for this and the typo right now.
Unfortunately we probably can't do much about the driver issue since it's DTP's API that is failing...but lets get a reproducable case and we can talk to the DTP guys about it.
