Java EE (Java Enterprise Edition) General Discussion

I'm creating a DOM tree using JDOM. All attribute values are retrieved from a database. I setAttribute:

element_xx.setAttribute("attribute_xx", resultSet_xx.getString("RS_Column_xx"));

However, if the value (from resultSet_xx) contains null, an exception occurs:

Exception:
The data "null" is not legal for a JDOM attribute: A null is not a legal XML value.

I don't want to validate each data inside the resultSet against null values before setting the attribute. Please advice.
