Custom Exception messaging

[fortm]

I have added a unique constraint to a field in ROO generated entity as shown below -

@RooJavaBean
@RooToString
@RooEntity(finders = { "findEmployeesByEmployee_id" })
public class Employee {

	@Column(unique=true)
    private Integer employee_id;

Now, when I try to insert same employee_id twice , the following stack message with full stack trace is thrown on user screen -

org.hibernate.exception.ConstraintViolationException: could not insert: [com.kreativ.kerp.domain.Employee]; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: could not insert: [com.kreativ.kerp.domain.Employee]

On the same time, in apache log, it says -

2012-03-12 15:57:18,395 [http-8080-1] ERROR org.hibernate.util.JDBCExceptionReporter - Duplicate entry '1' for key 'employee_id'

How can I print some useful message to user that this id must be unique instead of showing full stack trace.

I worked this around by creating some more views with those error messages and same layout.
So, in case of error, I redirected to the corresponding error message view.

Not the best solution, but it worked ..
