Hello, I am a little bit newbie with hibernate.
Here is my doubt, I want to Truncate a table, (delete all rows) and add an arraylist of objects to the this table. Like a replace

Here is my code



Here is my mysql code





The mysql table truncates, but the arraylist is not added

Error log :

7204 [btpool0-2] ERROR org.hibernate.util.JDBCExceptionReporter - Column 'nombre' cannot be null

You defined the column nombre as "not null". Obviously at least one of the rows you want to create after truncating has a null-value for that field.
