I am using MySQL v6.0.1

To test the Hibernate tools I created a couple of simple MySQL tables. In MyEclipse in the Hibernate view I selected the tables and Hibernate Reverse Engineering to generate the Hibernate classes, etc.

When I bring up an HQL window, type “from myTable” and go, I get the error:

Error Building Session Factory
A session factory for this …

Reason:
could not instantiate id generator

I’ve tried just about every possible id generator option with the same results.
I cannot find anything on any forums or in the Bauer-King book.

How do I correct this problem?

Thanks,

Frank,
Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Can you switch to a new workspace, create a new project and try working with the HQL editor again. Do you still run into the same issue ?

I think I figured out what was going on here.
I deleted all the generated java files at one point to try to cleanly re-gen everthing, but accidently also deleted the hiernate.cfg.xml file.

Not surprising that things didn’t work right, but unfortunately the error message was totally misleading.

Glad you figured it out.
