Hi,

When I try to assign a nullable database column to a primitive type, i am getting this "PropertyAccessException". But if i convert that to a wrapper type (i.e. from short to Short) then i am not getting any problem.

But i want to have primitive type in my POJO as it is easy for calculations. Is there a solution where i can have java primitive types in the POJO and still i can asign it to nillable database columns.

I am also providing all the necessary data for your reference.

Thanks in advance

Which jdk do you use?
If you use jdk 1.5, your "easy for calculations" is no problem since:



works with no problem...

Hope this helps! Thanks,

Hey Orome,

Thanks for the reply.

I am using JDK1.4 and unfartunately we can shift to JDK1.5.
Is there a solution other than changing all primitive types in POJO to wrappers when using JDK1.4?

Cheers

Use "DEFAULT" in DDL or transform values using custom type if "default" is application specific (see standard implementation for example).

Hi baliukas,

Can you explain me the solution again clearly. I am new to hibernate.

Thanks
