How to limit String length

I need to create restriction on String field.
In an ideal situation - if inserted data length exeed permited length the program should create warning, and cut to permited lenght if user insist.
I try to use length in <property> element, in mapping file, like

Code:

it not helps. In db column reg_code got 40 varchar and if I put in program 12 chars - all of them in database.
The only possibility I found - to put into bean file

Code:

   public void setRegCode(String regCode) {
      this.regCode = regCode.substring(0, 10);
   }

But this "method" quite stupid
db - mySQL 5.0.22

Your database field length should also be 10 Hibernate doesn't limit the Field length to the one in the mapping file, but you can analyse the Mappings Files during runtime and do the validation there, you can also create a BeanInfo that has the Information of the POJO, this BeanInfo can validate the POJO then or even the newest Version of Hibernate 3.2 can do this validation. Look inside the Manual there should be some example how to use validation in Hibernate.
