Hello everyone,
I'm in a bit of a quandry.
I'm new to Java, and even newer to Hibernate, and am trying to do a bit of basic Java programming using Hibernate to get me started.
Unfortunately, it's not going so well with an error cropping up that I can't sort out.
The error, and the code I'm using, is as follows:

}
I've tried lots of solutions that were available online, but couldn't get any of them to work for me...this may well be because of my lack of Java/Hibernate knowledge, and not being able to apply them to my situation.
Any help will be hugely appreciated!
Robin :-)
