Hi,
Im using MyEclipse 5.5 M1 and I’m having serious problems with the hibernate reverse engineering from DB.
Many times i get errors but some times i can generate the files without a trouble. I’ve spent many hours trying to find a common pattern for the problem without luck.
The 2 most common errors I’m getting are:

I’m using MyEclipse 5.5M1, SpringIDE 2.0.0.v200701250610 and Subclipse 1.2
Hope you can help me
