Hi everyone,

I have read a lot of posts about this and would like some more information. Please read on.

I have created a database schema using hibernate, and a another colleague is inserting a large amount of data. When I use the hibernate generated database with test data the data access objects work, when i use the hibernate database with the entire dataset I have the following error:

org.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of <package>.<class>.setField1 etc

I noticed:
1- The field name "Field 1" does not belong to the class specified within the package declaration.

2 - When i set hibernate.cglib.use_reflection_optimizer= false within the hibernate.cfg.xml it doesn't give me any extra information and if I block it out it doesn't change anything either. Am i setting this property in the right location??

I assume there is a small difference between the two databases that could be causing the problem. I've been checking to make sure all the types match etc. If you could point me in the right direction as to how to retrieve more information about the error, where the problem is etc or other areas I should be investigating would be appreciated.

Thanks, Alyssa.

Usually this happens if a column is nullable and your property is an int / long / .... (which can't be null) and not an Integer / Long / ....


You have two options:
- change the constraint of the database column to "not null"
- change the types of your class to Integer / Long / ....

Thanks for your response!

I've looked into the database and a number of the fields are null.

Changing the types of your class to Integer / Long / ....

Do you mean within the hibernate files, i.e. the class files for each of the tables and the mapping files? I havent specified a type within the mapping files.

Or

Within my data access objects? I have a method to retrieve a record based on an id.

I went through and updated a number of the records to see if it would work (inserting data into the nulls) the number of links to other tables makes it impossible.
