Is there any sample java code for calling a function that returns a sys_refcursor?

I have a stored procedure like this:
CREATE OR REPLACE FUNCTION Batch_Process ( p_active_dt IN DATE,p_truncate IN CHAR)

RETURN Types.cursor_type
AS
st_cursor Types.cursor_type;

.....

END Batch_Process

and the Mapping
