I have a mapping problem. I run my main program and Hibernate throws a MappingException. When I print it, it looks like this:

ERROR = net.sf.hibernate.MappingException: Repeated column in mapping for class net.sf.hibernate.CustomerorderT should be mapped with insert="false" update="false": COUNTRYCODE


Now, According to documentation section 8.2 Limitations
(http://www.hibernate.org/hib_docs/reference/en/html_single/#inheritance-limitations) it says that:



Apperantly I have more then one column that it maps to and I use the inverse="true" but that didn't give me any help.

Anyone knows what the problem can be and how to solve it? Check out my xml file and the code around the red section. I think that's where the problem is but I can't get my finger on it.

Nobody got any idea that can help me??

Hi there , I am also getting the same error. Did you solve your problem

Razi

no link witrh inverse="true"
Check in one mapping file each column name. There should not be any dupe.
If true, the put insert="true" update="true" on the other properties
