Hi,

I am writing a utility that uses FXMLLoaderFactory to load an FXML and use dependency injection with the controller. (The reason behind this is that the FXML is loaded from a server and is not located inside the bundle.)

The issue that I am facing is:

javafx.fxml.LoadException: 
	at javafx.fxml.FXMLLoader.constructLoadException(FXMLLoader.java:2605)
	at javafx.fxml.FXMLLoader.access$700(FXMLLoader.java:104)
	at javafx.fxml.FXMLLoader$ValueElement.processAttribute(FXMLLoader.java:918)
	at javafx.fxml.FXMLLoader$InstanceDeclarationElement.processAttribute(FXMLLoader.java:967)
	at javafx.fxml.FXMLLoader$Element.processStartElement(FXMLLoader.java:216)
	at javafx.fxml.FXMLLoader$ValueElement.processStartElement(FXMLLoader.java:740)
	at javafx.fxml.FXMLLoader.processStartElement(FXMLLoader.java:2711)
	at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2531)
	at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2429)
	at org.eclipse.fx.osgi.util.OSGiFXMLLoader.loadWithController(OSGiFXMLLoader.java:440)
	...
Caused by: java.lang.ClassNotFoundException: de.emsw.gosa.product.ega.controller.DokumenteController cannot be found by de.emsw.gosa.fx.util_1.0.0.qualifier
	at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:439)
	at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:352)
	at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:344)
	at org.eclipse.osgi.internal.loader.ModuleClassLoader.loadClass(ModuleClassLoader.java:160)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	at javafx.fxml.FXMLLoader$ValueElement.processAttribute(FXMLLoader.java:916)
	... 132 more

The reason is that the controller class is not in the same bundle with the utility class. Is it possible to set the class loader for FXMLLoaderFactory, so that it searches in a bundle that I can specify?

Thanks!
Christoph

So I guess you better use InjectingFXMLLoader, not? FXMLLoaderFactory in
simply wrapping that one. Disadvantage you get a direct dependency on
IEclipseContext.
