Hi expert,

My latest attempt is changing to @GeneratedValue(strategy = GenerationType.IDENTITY) and at least I get less error, out of consolation.

But, I hope to get some advice as to how to overcome the following error :

Code:

I have tried many times making sure that I have entered a tutorNRIC that never entered before. I checked my database schema and the fields is indeed indicated with a not null. I searched the stackoverflow for clue but nothing seems to help.

I really don't know who to ask for help already.

Hope someone can advise me how to rectify the problem.

Tks.

Try adding statement logging as explained in this article.

Then you will know the exact statements that get executed.

Hi Vlad,

First, thanks for the logging advice. It is a great clue to a novice like me.

Can I know if Log4j2 is it possible to do the job ?

Anyway, here's the latest error which I can't make head or tail out of the stacktrace. Hope you could me give me clue again what is wrong. Also, I realised now that all the schema that I have created manually at MySQL are all gone !!! Help.

That's because you use the hbm2ddl to recreate the schema. Unless you read the Hibernate User Guide, you are going to make many such mistakes.

So, start with the User Guide and continue with these tutorials and you'll find all the answers.

Thank you. Vlad has told me to use Update and I was wondering why it could be wrong.

I have copied and pasted another person's cfg.xml file and he has used 'create'. So sorry guys I have posted something without going thru carefully. It makes me wonder if I am really suitable to do 'programming'...

Thanks and so sorry for the trouble I have created.

Hb2ddl is only suitable for prototyping and update is a much safer choice than create.

Not only that I've done thousands of mistakes myself, but I'll do other mistakes in the future as well. As long as you are learning from them, it's all part of the game. If you enjoy programming, then you know you have made the right choice. Happy coding.

Thanks Vlad, I have recommended your book to the national library board and hopefully they will buy many copies :)

Regarding the proxy source that you mentioned, do I just drop the entire files to the source folder in my Eclipse in order to use it ?

Woohoo!

Do you mean the datasource-proxy configuration? Usually, if you have config files, they go to the src/main/resources folder. That's a Maven config convention and works no matter what IDE you might be using.
