/*@lineinfo:user-code*//*@lineinfo:140^5*/ return __jPt_result; } }/*@lineinfo:generated-code*/ Notice that the generated AddressAuto class code has additional code that employs SQLJ to get the connection information. It uses this connection to invoke the method get_address() of the object type address in the generated wrapper method getAddress(). The second generated Java file for the class MyAddressAuto (edited for clarity) is as follows: /*@lineinfo:filename=MyAddressAuto*//*@lineinfo:user-code*//*@lineinfo:1^1*/ package book.ch10.jpub; /* Some other imports deleted for clarity */ import oracle.jpub.runtime.MutableStruct; import sqlj.runtime.ref.DefaultContext; import sqlj.runtime.ConnectionContext; public class MyAddressAuto extends AddressAuto implements SQLData { public MyAddressAuto() { super(); } /* superclass accessors */ /* Code for accessor methods (setter and getter of various attributes) are generated within comments by JPublisher these have been deleted for clarity */ /* superclass methods */ public String getAddress() throws SQLException { String __jRt_0 = null;

The following statement sets up the SQLJ runtime context. As of 10g Release 1, if you try to invoke the wrapper method without executing this statement, you will get the following exception: found null connection context. Note that this problem does not exist if you use JPublisher to generate wrapper methods that implement the ORAData and ORADataFactory interfaces (as you will see shortly). address.setConnectionContext( new sqlj.runtime.ref.DefaultContext(connection)); Note how we can use getAddress() without passing the Connection object. As shown earlier, JPublisher takes care of passing the connection object internally in its implementation using the SQLJ runtime context. System.out.println( address.getAddress() ); } } finally { JDBCUtil.close ( rset, pstmt, connection ); } } } This concludes our discussion of using the SQLData interface. We will now discuss how to use the Oracle extension ORAData and ORADataFactory interfaces in JDBC programs. We will then compare the pros and cons of the SQLData and ORAData interfaces. The next section presents an overview of the interfaces ORAData and ORADataFactory.

Instead of using custom classes that implement the standard SQLData interface, we can use custom classes that implement the Oracle proprietary interfaces ORAData and ORADataFactory. The ORAData interface provides more flexibility as compared to the SQLData interface. For example, it lets you provide a mapping between Java object types and any SQL type supported by the oracle.sql package. Later, we will examine a detailed comparison between using the standard SQLData interface and using the ORAData and ORADataFactory interfaces. Let s start off with the definitions of ORAData and ORADataFactory: public interface ORAData { Datum toDatum (OracleConnection connection) throws SQLException; } public interface ORADataFactory { ORAData create (Datum datum, int sqlTypeCode) throws SQLException; }
