I'm using mySql and I have a table with a BigInteger ID field that i can't modify. I need to let the database to increment on his own the value of the field, but I can't find a suitable generator for my Id to put in the hbm.xml configuation file for the class. I search the forum but the solution with the definiton of a custom type don't work because the generator (increment) will still accept only long, int and short.
Can someone help me? Thanks.

Have a look at the generator type select in the Hibernate reference

What is the possibility to tell hibernate not to handle the Id increment but to let to Mysql do the job.

do you have a spelling mistake in your mapping?
HdDatUId instead of hdDatUId
