Wonder prevents you getting burned by not letting you play with fire ;-)

I'm trying to switch a WOApp that has a framework with my model

Quickstart guide, but the following error occurs when the
application launches:
[main] WARN er.extensions.ERXEntityClassDescription - Invalid
class name for entity: Account exception:
java.lang.ClassNotFoundException: Account using
com.webobjects.eocontrol.EOGenericRecord instead
For the record on a google search. The problem above is if you put
the classes for your entities in packages. e.g. framework/sources/
com/myproject/entities/Account.java.
If your EOModel lists Account as the entity name and Account as the
class name, in a standard WOLips / Eclipse project that uses a
framerok - this will work. WO at runtime is able to find Account
without any difficulty.
Switching to Project Wonder (use of ERXApplication... etc), this
breaks, because whatever classloading mechanism Wonder is using -
it is unable to find the class for the entity unless the full
package name is specified. ie. The EOModel needs to list Account as
the entity name, and com.myproject.entities.Account as the class
name. This solves the issue.
I'd say that regardless of what you are using, the class name in the
model should match the fully qualified class name. Anything else is
playing with fire.
