Netbeans persistence I added new column to the database how package.persis's classes are generated

Question

I have a program on NetBeans already programmed by another programmer where he used the persistence on it. This program is linked to the database.

I wanted to add a column in the database and show it in the NetBeans project. But this column shows "error", and the table in package.persis doesn't show me the new column that i added.

So how can I add the new column to the table? because I think there's a way to automatically create the classes of this package.

Thank you for your help.
