I have a JSF-Form and I want to save the inputs with hibernate in a MySQL DB.
I create a table with 20 columns. Every column could be not null.
I think the hibernate mapping is OK.
I get the exception "Column 'betriebsmittel' cannot be null".
Thats right, because don't want that the columns are null.

When every column could be null, the action-method saves in every column "null" and in the column id (primary key) 0. But I don't want that.

I hope anyone can help me.....

this exception arise when when you are trying to insert a null value where not-null is true.please check ur mapping file carefully that it should have property tag with not-null="true".
So you include not-null="true" attribute in all property tags.
