You're using a class in the com.bean to get the resource, which means using the relative path com/gui/HelloWorld.fxml creates a url that would point to the HelloWorld.fxml in the com.bean.com.gui package.
In this case you either need to use the ClassLoader with the same relative path:
this.getClass().getClassLoader().getResource("com/gui/HelloWorld.fxml")
or use a path relative to the classpath root
this.getClass().getResource("/com/gui/HelloWorld.fxml")
