Problem with OUT parameter

Question

Hi,
I have a stored procedure which has an OUT param which returns the following user defined
type.
--Create a type
CREATE OR REPLACE TYPE USER_TYPE
AS object
     CODE VARCHAR2(2),
     NAME VARCHAR2(5),
DEFINE CLOB
Iam calling the stored proc in java and i used the
pstmt = con.prepareCall("{ call USER_TYPE_PKG.CHECKTYPE(name=>?,type=>?)}");
pstmt.setString(1,userId);
pstmt.registerOutParameter(2,Types.*STRUCT*); ---> What type should i use here. Iam getting error for this.
and also how do i get the values of CODE,NAME and DEFINE inside the type in java.
Thanks.

If you are using TopLink, you can map the Struct to a Java class using an ObjectRelationalDataTypeDescriptor. Then you can use a StoredProcedureCall obejct to pass the Java object to/from the database and TopLink will handle the JDBC and Struct conversion for you.
For direct JDBC, when you register a Struct OUT paramater you must pass the Types.Struct as well as the OBJECT TYPE name.
pstmt.registerOutParameter(2,Types.STRUCT, "USER_TYPE");
