I can reproduce the bug. Method isDataFlavorSupported returns true for DataFlavor.javaFileListFlavor when pasting a file from NetBeans to my application, but getTransferData(DataFlavor.javaFileListFlavor) returns null. Data flavor javaFileListFlavor is added to the transferable in method DataNode.addExternalFileTransferable(), but retrieving of the data value in the second application is broken. I'm not sure whether this is a bug in NetBeans or in JDK. It'll require deeper investigation. Thank you for reporting.

I've been adding drag-and-drop support to a Java app I've written. I created a form with a JTextField and added my own TransferHandler to it. I'd like to be able to drag and drop files from the Projects window onto this field and have the text field automatically fill in the full name of the file. While the TransferSupport returns true when I query it with support.isDataFlavorSupported(DataFlavor.javaFileListFlavor) when I get the data with Object data = xfer.getTransferData(DataFlavor.javaFileListFlavor); I am given an empty list. The following exception is also thrown whenever I do a drag-and-drop from the projects list into my application: Exception "java.lang.ClassNotFoundException: org.openide.loaders.DataObject"while constructing DataFlavor for: application/x-java-openide-dataobjectdnd; mask=1; class=org.openide.loaders.DataObject It would be nice if the drag and drop support was extended to include DataFlavor.javaFileListFlavor.
