Looks like theres some kind of type mismatch problem (your database column type and your Bean property type) and hence the exception.

How are you creating your Hibenate Mappings ??? Are you using any tools? Check your column type in the mapping file  with the actual DB column type ... And could  you  provide more information about what exactly are you trying to do ???

Its possible that the issue is with the driver i.e. driver is not converting appropriately.
Any clues ??
