I am getting a MappingException error as follows:
net.sf.hibernate.MappingException: duplicate import: CaseVO

I don't see anything wrong with my mapping file. Anyone have any suggestions on what type of things to look for that might cause this error?

Thanks..... :)

I've gotten that error when using the Ant tasks. It happens if you point to a cfg file that lists CaseVO as a mapping, and then you also list the mapping in the Ant task (<fileset><include name="...). You have to specify one or the other, not both. I think you can also make the same mistake in the eclipse plugins.

If I change the class name of CaseVO to CaseVOX in the mapping file class tag everything works fine. When I change it back to CaseVO the error comes back. This tells me there is something somewhere referring to caseVO, but I am not sure where to look.

Hmmm, interesting. I am using an ant task as well, but don't see anything referring to the CaseVO.hbm.xml. I do have an include as follows:
<include name="**/*.hbm.xml"/>

Could this cause the problem, or is it probably something else?

I never had an issue until I started adding more properties to my CaseVO.

It can cause the problem if the configuration file your task points to also lists CaseVO in a <mapping> tag. It looks like you are using H2, and I only used H2 ant tasks briefly, so I don't remember what they look like, but somewhere you point to XXX.cfg.xml. Make sure that cfg.xml file doesn't have mapping tags. If it does, either remove them, or remove the <include name="**/*.hbml.xml"/> tag. If you have both, Hibernate will try to import the mapping twice and throw that exception.

Odd. After reading the following post in a different forum, I deleted the folders in my classes directory and all is well. Somehow this fixed the error.

I am not exactly why this fixed the issue so if anyone has a clue please let me know.

Thanks.
