using hibernate 3.0.

Is it possible to map a bean with primitives directly to a table instead of using wrapper classes in the bean?

Problem comes when using hibernate to fetch data from a table. If this table happens to have null values in number columns then it is unable to set the null or blank value in the bean's primitive attribute.

Well it is obvious that primitives can not be NULL! So they can only be mapped to MANDATORY columns of database, otherwise errors will occur when fetching the entities.
