You google the error. (Use your google foo young warrior!)

And if that doesn't help you post the snippet of code that is causing the error and the full stack trace.

Hello guys.

Well, finally after "solving" ( i dunno yet if its gonna worl the solution or what) the problem with the "execute SQL" Im going trough the tutorial, IO read I should use the Veogen due that im under leopard. so I did what the wiki says

http://wiki.objectstyle.org/confluence/display/WOL/Velocity+EOGenerator+%28Veogen%29

no problem there.

so comparing the sample code I downloaded from the site where the tutorial resides and with the code generated (DisplayBoard.java and _DisplayBoard.java) there are some diferences, i.e the constructor its missing, I don't have any issue in putting just super();, but Im wondering if I will have some p[roblems in the future...


Veogen templates do the right thing. Don't worry about the missing constructor, do not added it, you will (and should) never call it directly.

When creating a new DisplayBoard you'll see in the code for the tutorial that Janine uses:

DisplayBoard displayBoard = (DisplayBoard)EOUtilities.createAndInsertInstance(session ().defaultEditingContext(), "DisplayBoard");

This is such a common line of code that the Veogen templates generate factories that do that for you.

So you can call:

DisplayBoard displayBoard = DisplayBoard.newDisplayBoard(session().defaultEditingContext());
