I try to deploy JavaFX FXML app as Web Start but I have got exception bellow. Jar is normaly working and also works deployed as self-contained app. I have build project in NetBeans v. 8.0.2. I have found so many similar threads over internet but either solution works nor I was thinking that solution is the right one.
In all solution has been identified this row
SomeClass root = FXMLLoader.load(getClass().getResource("someFXML.fxml"));
as a cause.
Solutions was:
1. Use path /someFXML.fxml.
2. Use FXMLLoader.load(getClass().getClassLoader().getResource("someFXML.fxml"));
3. Use FXMLLoader.load(getClass().getClassLoader().getResource("packageName/someFXML.fxml"));
4. Checks for files presence.
5. Signing the jar.
I have tried perhaps all of them.
I am thinking that the solution not depends on row shown.
