This week's giveaway is in the Java/Jakarta EE forum. We're giving away four copies of Java EE 8 High Performance and have Romain Manni-Bucau on-line! See Anyway, I've built the majority of the GUI and the database, and got them connected. What I can't do however, is get records inserted into the table (and presumably update and delete records too as I haven't tried doing them yet!) . This is not because of a lack of SQL knowledge, I just don't know how to get the data from the GUI to the database. I've tried a number of different ways (as can be seen in the code)but I don't seems to be getting any nearer.
Below is my code and then the errors I've been getting.
