No, I did not change the model. I just experimented migrations with postUpgrade creation of new entities, step after step, one entity, then other and so on, until I stumbled on a specific one that caused me trouble. I revised the model and tried some advices for MySQL configuration but found no solution. > > Because the reason is not apparent to you, does not mean that the reason is > Eclipse.

When I have this kind of problem my first thought is: what is my mistake? Then I look for errors I could have made. I normally put the blame on myself first, perhaps a problem of a low esteem programmer… > > See java.lang.NoClassDefFoundError: > com/webobjects/_eoproject/_WBInterfaceDescriptor.

The model is in the framework I made specifically to hold it, alongside with the rules I use (I created a rule file for each entity and load them in the properties file). The framework indeed do not have JavaEOProject for default, probably because the project template doesn't include it. I added it to the framework and the error persists. > > Without seeing the full log, I can't guess why. But differences in the > frameworks included in each project could be the reason.

Two of the applications are D2W apps where the differences between them are the entities they work with and the rule files specific for each. These are the administrative backend applications. The third application is a regular DirectAction-based WO application that will be the store-front for our customers' customers (bad English here?). > > >> One of the problematic applications I was able to start from scratch by >> deleting the project and its files, copying a different working one and >> modifying it with the classes and user interface I started developing for >> the former.

If this is not a workspace problem I do not know what could cause it. Maybe my environment, my Java installation, other extensions or something in the system is causing the problems. I am seriously considering buying a HD to do a clean install of Mountain Lion and dedicate it to Eclipse development.
