Using the Transaction's Savepoint and getting Exception

Hi,

my code is as follows:

connection.setAutoCommit(false);

Statement stmt = con.createStatement();

execute Query 1. // 1

Savepoint s1 = conn.setSavepoint(); // 2

execute Query 2. // 3

i m using the JDBC-ODBC bridge driver.

when the statement 2 executed the exception occurs as follows:

java.lang.UnsupportedOperationException

at sun.jdbc.odbc.JdbcOdbcConnection.setSavepoint(Unknown Source)

I m not able to understand why it is coming.

Thanking u.
