问题
I am using the latest version of EclipseLink (2.2.0) with SQL Server 2005.
Generating the classes, the type NVARCHAR is mapped to type Object in the classes.
I suppose it should map to type String.
Why is this happening?
回答1:
How are you generating the classes? Are you using Eclipse Dali?
I would just change the generate code to String. Perhaps report a bug with the IDE you are using. EclipseLink itself, does not generate classes.
