Migrate Java to 10g

Question

Hi
We have the following java code that runs with 9i in the database.
Connection conn = DriverManager.getConnection("jdbc:default:connection:");
     PreparedStatement pstmt = conn.prepareStatement("select version_number from version");
     try
          ResultSet rset = pstmt.executeQuery();
          try
               while (rset.next())
               String theString = rset.getString(1);
               System.out.println(theString);
          finally
          rset.close();
     finally
     pstmt.close();
We load the same code to 10g (with loadjava) we get the error:
ORA-29532: Java-Aufruf durch nicht abgefangene Java-Exception beendet:
java.sql.SQLException: Ungültiger Spaltenindex
at ResultSet.getString(1);
Are there any known problem with 10g?

Does "totally different schema" mean "totally different data model"? If so, there is no automatic way for any tool to ensure that the data in two different data models matches-- you would have to write custom scripts for that sort of thing since only you know how the data is supposed to be translated from one data model to another.
