I switched to standalone because I couldn't get the EO generator working inside Eclipse.

I'm using 1.0.2 of the standalone Entity Modeler - quite recent :) I haven't set up any class paths or anything. I couldn't find any release notes or wiki page 

I do not like using Eclipse, in spite of all the hard work from you and the rest of the contributors. Its much appreciated, but I'm one of the programmers that just doesn't get Eclipse. I much prefer my ant scripts and IDEA. But, each to their own :)

So I tinker with Eclipse now and again - but when it fails to work, I throw my hands up!! I'm sure if I used Eclipse as often as everyone else here, I'd understand it - but I feel so unproductive while using it. I'm always working out how to get something done. Whereas with IDEA (and admittedly the Tiger XCode tools), I've already worked out how to get my projects building and running the way I like them.

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.
