Savepoint in jdbc

Hi all,
I want to use savepoints to execute my functions.Functions do not have an
explicit commit statement.


On executing the folowing code snippet I get Error:


c = DriverManager.getConnection(url, username, password);
System.out.println("connection successful");

c.setAutoCommit(false);
Savepoint starttrans=c.setSavepoint("CustomBusinessLogic");


//First Function
CallableStatement stmt = c.prepareCall("Begin ? := fnCreateVoucherTb(?,?,?,?,?,?,?,?); End;");
stmt.registerOutParameter(1,Types.INTEGER);
System.out.println("Executing Create Function");
stmt.setInt(2 , 1);
stmt.setString(3 , "Nu");
stmt.setString(4 , "BNumber");
stmt.setString(5 , "29-Sep-05");
stmt.setString(6 , "29-Oct-05");
stmt.setInt(7 , 3);
stmt.setInt(8 , 3);
stmt.setString(9 , "29-Sep-05");
stmt.executeUpdate();
pk = stmt.getInt(1);
System.out.println(pk);
stmt.close();

//Second Function
stmt = c.prepareCall("Begin ? := fnSaveVoucherTb(?,?,?,?,?,?,?,?,?,?); End;");
stmt.registerOutParameter(1,Types.INTEGER);
stmt.setInt(2,1);
stmt.setInt(3,127);
stmt.setString(4 , "FirstFunction");
stmt.setString(5 , "BatchNumber1");
stmt.setString(6 , "03-OCT-05");
stmt.setString(7 , "03-OCT-05");
stmt.setInt(8 , 3);
stmt.setInt(9 , 3);
stmt.setString(10 , "03-OCT-05");
stmt.setString(11 , "2005-10-05 10.58.38.6");
System.out.println("Save Function: set the parameters");
stmt.execute();
System.out.println("Procedure Executed");
pk=stmt.getInt(1);

c.rollback(starttrans);
}
catch(SQLException e)
{
System.out.println("Error Occured" + e);
}


ERROR::
Error Occuredjava.sql.SQLException: ORA-01086: savepoint 'CUSTOMBUSINESSLOGIC' never established

Ann,
Welcome to JavaRanch!

On which line of code does the code throw the exception? When you set the savepoint at the beginning or when you rollback to it?
