if it's a first hearing it should be in the magistrates' court where the offence was committed. you won't find it online. try ringing the local courts once they're open in the morning, and ask for the Listings Office. if it's not the right court they should be able to advise you.
all morning cases are listed for 10am, afternoons at 2pm. when you find the court, when you go in (assuming you are) there will be lists displayed showing which case is in which court. if you're not going you can ring later in the day to find out what happened.
