About JPublisher Output

JPublisher generates a Java class for each object type that it translates. For each object type, JPublisher generates a type .java file (or a type.sqlj file if wrapper methods were requested) for the class code and a type Ref.java file for the code for the REF class of the Java type. For example, if you define an EMPLOYEE PL/SQL object type, JPublisher generates an employee.java file and an employeeRef.java file.

For each collection type (nested table or VARRAY) it translates, JPublisher generates a type.java file. For nested tables, the generated class has methods to get and set the nested table as an entire array and to get and set individual elements of the table. JPublisher translates collection types when generating CustomDatum classes but not when generating SQLData classes. JPublisher does not generate a type Ref.java file for nested tables or VARRAYs. This is because PL/SQL does not allow a REF to be made to these types.

For PL/SQL packages, JPublisher generates classes containing wrapper methods as SQLJ files. JPublisher also generates method wrappers in your class that invoke the associated package methods executing in the server. This is specified by the Include Methods option.

Note: Since version 8.1.6, the wrapper methods that JPublisher generates to invoke stored procedures are in SQLJ only. Classes generated by JPublisher that contain wrapper methods must be compiled by SQLJ.
