Problem with XSU when trying to execute pl/sql package returning ref cursor

Question

Hi,
I'm exploring xsu with 8i database.
I tried running sample program which I took from oracle
documentation. Here is the details of these.
------create package returning ref cursor---
CREATE OR REPLACE package testRef is
     Type empRef IS REF CURSOR;
     function testRefCur return empRef;
End;
CREATE OR REPLACE package body testRef is
function testRefCur RETURN empREF is
a empREF;
begin
OPEN a FOR select * from emp;
return a;
end;
end;
---------package successfully created-----
Now I use java program to generate xml data from ref cursor
------------java program ----------
import org.w3c.dom.*;
import oracle.xml.parser.v2.*;
import java.sql.*;
import oracle.jdbc.driver.*;
import oracle.xml.sql.query.OracleXMLQuery;
import java.io.*;
public class REFCURt
public static void main(String[] argv)
throws SQLException
String str = null;
Connection conn = getConnection("scott","tiger"); //
create connection
// Create a ResultSet object by calling the PL/SQL function
CallableStatement stmt =
conn.prepareCall("begin ? := testRef.testRefCur();
end;");
stmt.registerOutParameter(1,OracleTypes.CURSOR); // set
the define type
stmt.execute(); // Execute the statement.
ResultSet rset = (ResultSet)stmt.getObject(1); // Get the
ResultSet
OracleXMLQuery qry = new OracleXMLQuery(conn,rset); //
prepare Query class
     try
qry.setRaiseNoRowsException(true);
qry.setRaiseException(true);
qry.keepCursorState(true); // set options (keep the
cursor alive..
     System.out.println("..before printing...");
while ((str = qry.getXMLString())!= null)
System.out.println(str);
     catch(oracle.xml.sql.OracleXMLSQLNoRowsException ex)
System.out.println(" END OF OUTPUT ");
qry.close(); // close the query..!
// qry.close(); // close the query..!
// Note since we supplied the statement and resultset,
closing the
// OracleXMLquery instance will not close these. We would
need to
// explicitly close this ourselves..!
stmt.close();
conn.close();
// Get the connection given the user name and password..!
private static Connection getConnection(String user, String
passwd)
throws SQLException
DriverManager.registerDriver(new
oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@xxxx:1521:yyyy",user,passwd);
return conn;
when I ran the program after successful compilation,I got the
following error
==========
Exception in thread "main" oracle.xml.sql.OracleXMLSQLException:

============================
Can anybody tell me why I'm getting this error.Am I missing any
settings?
thanks

We are using 8.1.7 Oracle db with latest xdk loaded.
