What version are you using? I honestly haven't tried reverse engineer
in standalone. It works inside Eclipse ... It will have to have a
source for finding classpath information, so this very much depends on
what IDE you are using. If you're using Xcode, there is no support
for parsing its project files to find classpath, so you would have to
define it manually in an EntityModeler.classpath
(or .EntityModeler.classpath) file located in the model folder or in
one of the folders above it (or home directory, or ~/Library or ~/
Library/Preferences). This file should point to all of the Jars
necessary to use EOF, one jar per line.
The error you're seeing, though, implies to be that you literally
don't have an implementation of class loader factory, which I would
think means you have an old Entity Modeler.app, because I'm almost
positive there is an impl in the new one. If you're using IDEA or
Eclipse, it can parse the project files directly to load classpath
dependencies.

Subject: Re: Entity Modeler Reverse Engineer
I suspect that's a misleading error message ... Is there a stack
trace in the details of that error message? Althought, are you
running the standalone app or the one inside of Eclipse?

Hi, I really like the new Entity Modeler - shows a lot of promise :)
However, I get this error message when I try to reverse engineer an
already existing mySQL database.
"There was no valid EOF ClassLoader factory defined."
Steps to reproduce are fairly simple :)
1. Have a mySQL DB that you know the password etc
2. Create new Model File in Entity Modeler
3. Enter Default settings, using com.mysql.jdbc.Driver as the
Driver, and jdbc:mysql://localhost/myDB as the URL.
4. Click on the model, and choose "Reverse Engineer"
Behold the error message as listed above.
Is this just not implemented yet? Or am I doing something
unexpected? :)
Thanks.
