SOLVED: I ignored warnings about primary keys that were missing. After fixing those warnings it worked.
I am running a fresh install of Eclipse 3.1.2 and Hibernate tools 3.1.0.beta5.
I made the appropriate files for reverse engineering.
Under Hibernate Code Generation -> Exporters I checked: Use Java 5 syntax, Generate EJB3 annotations, Domain code.
When I try to reverse engineer I get the following error message:
Code:
Error 2006-06-19 12:39:10.125 ERROR Worker-14 freemarker.runtime -

If I instead checked: Use Java 5 syntax, Domain code, Hibernate xml mappings it works.
I am not experienced enough in Eclipse or with the Hibernate tools to know what could be causing this error.
Thanks in advance for any help :)
