While studying using Scala with JavaFX I have met the following code in a ProScalaFX example:
val resource = getClass.getResource("AdoptionForm.fxml")
if (resource == null) {
throw new IOException("Cannot load resource: AdoptionForm.fxml")
}
...
val root: jfxs.Parent = jfxf.FXMLLoader.load(resource)
Where do I put the actual "AdoptionForm.fxml" content in this case? Unfortunately I am neither familiar with using resources in Java.
I use SBT as the building system and Idea as an IDE.
There is a related question which suggests a way (putting the resource files in "src/main/resources" or "src/main/resources/packagename"), but it also says it doesn't work actually (needless to say I have tried).
src/main/resources is the correct location for placing resources in a default SBT configuration.
However, one has to be aware of the difference between getClass.getResource and ClassLoader.getResource. Using getClass.getResource("AdoptionForm.fxml") requires the file to be located in a path which corresponds to the package of the class.
For instance: If the class is located in com.domain.utils then the resource must be located at src/main/resources/com/domain/utils/AdoptionForm.fxml.
In order to switch from package-relative locations to absolute locations one can either use ClassLoader.getResource or just prepend the resource string with a /.
Example: getClass.getResource("/AdoptionForm.fxml") loads the resource from src/main/resources/AdoptionForm.fxml
