Structured type of data forinput parameters

Question

Help me please in my problem.
Can I sent in the parameter of PL/SQL function structured data type? RECORD for example.
Whatever:
PL/SQL:
"TYPE User_Data IS RECORD
(UserId NUMBER,
UserName VARCHAR2);
FUNCTION Get_Whatever
(i_data IN User_Data,
i_data1 IN NUMBER DEFAULT 0)..."
and java source:
"CallableStatement cst = conn.prepareCall("{? = call PACKAGE.Get_Data(?, ?)}");
try {
cst.registerOutParameter(1, OracleTypes.CURSOR);
cst.setObject(2, ?????????????);"
Can anybody help me?
Thanks in advance.

Actually it looks like you are tying to use a ref cursor. Here is an example:
* This sample shows how to call a PL/SQL function that opens
* a cursor and get the cursor back as a Java ResultSet.
import java.sql.*;
import java.io.*;
// Importing the Oracle Jdbc driver package makes the code more readable
import oracle.jdbc.driver.*;
public class retrefcur_samp
public static void main (String args [])
// throws SQLException
try
// Load the driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database
// You can put a database name after the @ sign in the connection URL.
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@ora8tst", "scott", "tiger");
// Create the stored procedure
init (conn);
// Prepare a PL/SQL call
CallableStatement call =
conn.prepareCall ("{ ? = call java_refcursor.job_listing (?)}");
// Find out all the CLERKs person
call.registerOutParameter (1, OracleTypes.CURSOR);
call.setString (2, "*");
call.execute ();
OracleResultSet rset = (OracleResultSet)call.getObject (1);
// Dump the cursor
while (rset.next ()){
System.out.println (rset.getString ("JOB"));
rset.close();
call.close();
} catch(SQLException esql) {
System.out.println("Trouble in river city ");
System.out.println(esql.toString());
// Utility function to create the stored procedure
static void init (Connection conn)
throws SQLException
Statement stmt = conn.createStatement ();
stmt.execute ("create or replace package java_refcursor as " +
" type myrctype is ref cursor return EMP%ROWTYPE; " +
" function job_listing (j varchar2) return myrctype; " +
"end java_refcursor;");
stmt.execute ("create or replace package body java_refcursor as " +
" function job_listing (j varchar2) return myrctype is " +
" rc myrctype; " +
" begin " +
" open rc for select * from emp; " +
" return rc; " +
" end; " +
"end java_refcursor;");
stmt.execute ("create or replace package java_ref_clean as " +
" type myrctype is ref cursor; " +
" function cleanup (cc myrctype) return number; " +
"end java_ref_clean;");
stmt.execute ("create or replace package body java_ref_clean as " +
" function cleanup (cc myrctype) return number is "+
" result number; " +
" begin " +
" close cc; " +
" end; " +
"end java_ref_clean;");
