how do i start and end a transaction with hsqlb?

Hello,

I would like to run a batch of statements and/or procedures and if
there is an exception rollback.

Something like:

   try
        {
            connection.setAutoCommit(false);
            //insert, update, delete statements and/or procedures
            connection.commit();
        }
        catch (Exception e)
        {
            connection.rollback();
        }

How do I setup hsqldb to do this?
