About Java Mapping Options

The mapping options you select for datatype categories determine the set of type mappings that JPublisher uses to translate object types and PL/SQL packages into Java classes:

For object types, JPublisher applies the mappings to the object's attributes and to the arguments and results of any methods included with the object. The mappings control the types that the generated accessor methods should support, that is, what types the get methods should return and the set methods should require.
For PL/SQL packages, JPublisher applies the mappings to the arguments and results of the methods.
For a collection type (that is, nested tables and VARRAYs), JPublisher applies the mappings to the element type of the collection.
For user-defined types (usertypes category) JPublisher generates CustomDatum classes or SQLData classes and generates code for collection and REF types.

You may select from the following mapping options:

Oracle Mapping represents data in PL/SQL format.
JDBC Mapping represents simple data types as Java primitive types.
Object JDBC Mapping represents simple data types as Java wrapper classes.
BigDecimal Mapping uses a common class to represent all numeric types.

You can map these data types:
