Hi,
I'm having getting this exception and I couldn't find anything like this on the web/faq/docs. I only found something similar on the forum but it didn't say anything I could use.
This is what I get. The strange thing is that I don't get this every time I run the app (It's a web app using struts), sometimes I works fine. What can be throwing this exception?
I'm using mySQL 5, tomcat 5.5, and the Hibernate version 3.0.
Thanks a lot,
Pablo.
