Java Database Connectivity (JDBC)

Hi,

I want to call a oracle procedure using hibernate. I just want my procedure to do some processing and has no out parameter. But as I have gathered from the docs - A function must return a result set. The first parameter of a procedure must be an OUT that returns a result set. This is done by using a SYS_REFCURSOR type in Oracle 9 or 10

I have made my procedure with an out parameter satisfing the above requirement.

Procedure:

CREATE OR REPLACE
PROCEDURE SPC_USER_DETAILS (User_cv OUT SYS_REFCURSOR) AS
v_User_id Number(38);
v_FIRST_NAME VARCHAR2(255);
v_LAST_NAME VARCHAR2(255);
v_email VARCHAR2(255);

BEGIN
OPEN User_cv FOR
SELECT * FROM contact;
loop
fetch User_cv into v_User_id, v_FIRST_NAME,v_LAST_NAME,v_email;
exit when User_cv%notFound;

insert into dummy_contact values (v_User_id, v_FIRST_NAME,v_LAST_NAME,v_email);
end loop;
close User_cv;
End;

Java code calling the procedure.

tx = session.beginTransaction();
session.getNamedQuery("prash_test");

hibernate.cfg.xml
<mapping resource="hibernate/test.hbm.xml" />

test.hbm.xml
<hibernate-mapping>
<sql-query name="prash_test" callable="true">
<return class="com.ni.genreg.presentation.formbeans.TestForm">
</return>
{ call SPC_USER_DETAILS(?) }
</sql-query>
</hibernate-mapping>

On running my java class, that calls the procedure, I dont get any errors. But the changes are not getting reflected in the database. I have tested the oracle procedure, its in working fine.

Any idea what I could be doing wrong in this approach?

Thanks in advance.
