I am using Eclipse 3.2 and 3.3 and both exhibit the same behavior.

When I use the Hibernate Code Generation Dialog, I have two configurations, one that I am trying to create a new database from java classes, using annotations, and the other is to go to another database and reverse engineer it, using annotations.

I am also using jdk1.6, on WinXP.

Hibernate Tools 3.2 beta 9 is also what I am using.

For the reverse engineering, the hibernate.cfg.xml works, as it is able to find the tables, and show me the schema of the tables, but, I have only created the other database, I am trying to get Hibernate to create everything.

When I select exporter->Schema Document I get this error, under both configurations, but when I don't select it, no error, but no java classes, just some html files and other resources.

I am not concerned with the lack of source creation, but the error message may be of interest, as it appears that you assume that some files will be created.

I made some changes to the reveng.xml file and it was able to create the files, but, I think having a possibility of an IndexOutOfBounds exception may be a problem.

So, most likely the problem with the other configuration is my fault also.

report in jira.
