POI-HWPF Read multiple word documents and write to 1

[Frank Ramm]

Hi,

i am writing a small program, that has create a new Word-Document on startup.
When you drop a word-document on the user interface, it would be read. I want to drop multiple files.
After the drop, the programm should write all data into a new word document. When i drop more files, it only writes the content of the last file.

At the moment, i dont know whats the problem.

Can you please suggest.

public class DocCreator extends JFrame implements DropTargetListener {
	private Container conPane;
	private Vector fileVector;
	private JList dropFileList;
	private JScrollPane sp;
	private String targetDir = "D:/test/";
	private String templateDir = "D:/vorlage/";

	public DocCreator() {
		conPane = getContentPane();
		initCenter();
		initFrame();
	}

	private void initCenter() {
		File source = new File(targetDir);
		File[] files = source.listFiles();
		fileVector = new Vector();
		for (int i = 0; i < files.length; i++) {
			if (files[i].isDirectory())
				fileVector.add("<dir>  " + files[i].getName());
			else
				fileVector.add("<file> " + files[i].getName());
		}

		dropFileList = new JList(fileVector);

		dropFileList.setDragEnabled(true);
		DropTarget dropTarget = new DropTarget(dropFileList,
				(DropTargetListener) this);

		sp = new JScrollPane(dropFileList);
		conPane.add(dropFileList, BorderLayout.CENTER);
		createDocument(templateDir, targetDir);
	}

	private void initFrame() {

	public void drop(DropTargetDropEvent e) {
		try {
			Transferable tr = e.getTransferable();
			if (tr.isDataFlavorSupported(DataFlavor.javaFileListFlavor)) {
				e.acceptDrop(DnDConstants.ACTION_COPY_OR_MOVE);
				java.util.List files = (java.util.List) tr.getTransferData(DataFlavor.javaFileListFlavor);
				int len = files.size();
				File file;
				for (int i = 0; i < len; i++) {
					file = (File) files.get(i);
					if (file.isFile()) {
						try {
							copyFile(file, targetDir);
							fileVector.add("<file> " + file.getName());
							dropFileList.updateUI();

							String path = targetDir + file.getName();
							readDocument(path);
							writeDocument(path, targetDir);
							

						} catch (IOException ex) {
						}
					}
				}
				e.getDropTargetContext().dropComplete(true);
			} else {
				System.err.println("DataFlavor.javaFileListFlavor is not supported, rejected");
				e.rejectDrop();
			}
		} catch (IOException ex) {
			System.err.println("IOException");
			ex.printStackTrace();
			e.rejectDrop();
		} catch (UnsupportedFlavorException ex) {
			System.err.println("UnsupportedFlavorException");
			ex.printStackTrace();
			e.rejectDrop();
		}
	}
