Javax.validation.ConstraintViolationException: Bean Validation restrictions (s) violated during preUpdate validation

I get an annoying error message when I try to insert a new element into many relationships using JPA 2.0, SpringMvc 3.0.

I have a table with states and another with Persons. A person can be connected with many states and the state with many people. In this particular case, I have listOfStates and then a person, and I would like to insert these elements into my many of many relationships.

ManyToMany Relationship (in STATE STATE)

//bi-directional many-to-many association to Appointment @ManyToMany(cascade=CascadeType.ALL) @JoinTable( name="PERSON_STATE" , joinColumns={ @JoinColumn(name="PERSON_ID", nullable=false) } , inverseJoinColumns={ @JoinColumn(name="CODE_STATE", nullable=false) } )

The DAO code I'm calling from my controller

 try{ getEntityManager().getTransaction().begin(); getEntityManager().persist(myPerson); IStateDAO stateDAO = new StateDAO(); for (int i=0; i<listOfStates.length; i++){ State myState = stateDAO.findState(listOfStates[i]); if (myState != null){ myState.getPersons().add(myPerson); getEntityManager().persist(myState); } } getEntityManager().getTransaction().commit(); getEntityManager().close(); } catch (RuntimeException re) { getEntityManager().close(); throw re; }

The funny thing is that this code works fine when I do not paste data from a web page. What am I doing wrong here? I already have some people and conditions in the database.

Full Stack Error Message:

 org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'preUpdate'. Please refer to embedded ConstraintViolations for details. javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'preUpdate'. Please refer to embedded ConstraintViolations for details.

Any pointer would be really appreciated. Thank you all in advance.

Wow! got it! I had to change the validation mode in my persistence.xml from Auto to NONE , which basically tells the application that it does not use bean validation at all. The error messages have disappeared and my DAO is working fine.

Exceptions indicate that the JSR 303 Bean Validation is being used , and Hibernate is configured (Persistence.xml) to check them before updating anything.

JSR 303 Bean Validation - These are annotations, such as:

  • javax.validation.constraints.NotNull
  • javax.validation.constraints.Size
