Datafx and Netbeans 8.0.1

[Dario]

Hello,

I started to run write the first datafx tutorial at:

http://www.guigarage.com/2014/05/datafx-tutorial-1/

I put all the code inside a Maven template generated by NetBeans. I changed the pom files to download data flow and core. The compilation process with success.

But, when I want to run it, I get this exception:

Any help will be appreciated.

Hi,

datafx can’t find your vxml file. When using maven by default any file that is not a java file must be in the src/main/resources folder. Maybe your vxml file is in the src/main/java folder?

FXML file not vxml :) that was a typo in my answer.

[Dario]

No Problem. I got it.

Thanks a lot for helping. I checked already and the fxml is in the right place. I spent hours in dealing with this error and I don't find where it is. Check in the attachment. Here is my project, very simple, but does not run.

Hope you have another idea.

Hi,

I found the problem.

Your controller class is in the package:

/src/main/java/com/mycompany/mymaven

and your FXML file is in the package

/src/main/resources/fxml

but should be in

/src/main/resources/com/mycompany/mymaven

In the FXMLController annotation you defined the FXML by "Scene.fxml" and therefore it must be in the same package as the controller. Just move the fxml file to

/src/main/resources/com/mycompany/mymaven

and everything will be fine :)

[Dario]

Thanks a lot Hendrik for your time and help,

Yes, now it works.  

[Hendrik Ebbers]

Perfect :)

I'm so glad I found this! Thank you. I had almost given upon DataFX, but turns out the problem is it's my first time using Maven. :)
