Thread: Embedded Derby & SE GUI (Netbeans 7.4)

Beginner with NetBeans and Java.

OK.

I have a GUI (SE Swing) that contains a JTable, 2 buttons and a JTextArea.

I have an Embedded Derby database with a single table.

I have done some research with regards to Derby and have (hopefully) realised that I can program the connection without using EclipseLink. But what I want to know is how to attach data from the database table to these separate parts of the GUI - some data to the JTable, (and when a row is selected in the JTable) a website (unique to each row of data in the Database table) to a button and an image (again, unique to each row of data in the Database table) to the JTextArea.

Are there any tutorials for this - reading the Oracle pages makes me more confused - or am I asking too much of Java and Derby?

Looking forward to positive responses.

Hi Kevin,

Step 1: I take it you mean a structured database with linked tables? That is: a table with the data for the JTable only, a table with the list of websites for the JButton and the same for the image.

Step 2: I have the GUI already created in NetBeans - have tried various ways to display the data although now I'm getting tired (I just want to finish the damn thing) so I haven't tried the programmatical way of connecting to the Embedded Derby database yet. I really am new to this so if you could hint at what type of method I should use that would be most helpful also.

BUT the database structure will be the next thing I must do (obviously from what you have said in step 1) and then I must check Step 2 with just showing the data in the JTable to start with and proceed from that point.

Thank you - sensei knows the way, the student must find the way.

Not necessarily. The data can be in any form or structure you can handle.

I take it then that you're using the Netbeans GUIBuilder and you know little to nothing about actual Java programming, at least graphical/GUI Java programming? If so, this is not a Java question, it's a Netbeans GUIBuilder question. We don't have many here (any?) who can help you with that. If not, then please describe specifically what you need help with.

I have created a embedded database with 4 tables linked with keys. Are you talking about something like Hibernate?

--- Update ---

Also, found an EventListener for the row of the JTable selected so this is what I shall be using.

OK. I'm actually having problems with the connection to the embedded Derby database. I'll need to check Hibernate for this of course.

Also, I must say that this is not a CRUD application that I am creating.
The application is to view the embedded database, when a row in the JTable is selected further data is supplied to the JButton (web site address) and JTeaxtArea (JPEG image).
I apologise for not saying this beforehand.

Also, I'm keeping the GUI I've created as it indicates for me a partial advance - if I were more experienced I would ditch it and use another approach.

Anyway, on to researching Hibernate for this.

OK.
Using Netbeans 7.4, I have hand coded a GUI (SE desktop distributable application), created a single table database (Java DB using 'Embedded' connection) and created (via a wizard in Netbeans) the 'Persistence.xml' file (Hibernate 2.0 setting).

As I'm at that stage of creating a (non-CRUD) database application what would be the next steps to take with Hibernate 2.0?
Would it be using NB wizards to create 'Mapping files and POJOs...' and the other Hibernate elements?

Any guidance/advice would be greatly recieved - I'm a little stuck at the moment, relatively new to Java but want to learn to create this application myself.
If there is a document/tutorial that provides these steps, please provide the link.
