application, it contains form generate reports for user in pdf format
and save it in temporary file.
when user view the archived report, he could save it in another path
(for example: myDocuments)... but the new saved file is empty except
from a logo
this is the code to save the pdf ... can anybody help my to find the
problem? thanx in advance

public void export(){
  Properties m_ctx=Env.getCtx();
  JFileChooser chooser = new JFileChooser();
  chooser.setDialogType(JFileChooser.SAVE_DIALOG);
        chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
        chooser.setDialogTitle(Msg.getMsg(Env.getCtx(), "Export"));
        chooser.addChoosableFileFilter(new
ExtensionFileFilter("pdf" ,Msg.getMsg(m_ctx, "FilePDF")));

        if(chooser.showSaveDialog(this)!= JFileChooser.APPROVE_OPTION)
         return;

        File file =
ExtensionFileFilter.getFile(chooser.getSelectedFile(),
chooser.getFileFilter());
        Viewer viewer = new Viewer();
        try{
         PDFGenerator.getPDFAsStream(new
FileOutputStream(file),layoutEngine.getPageable(false));
         file.createNewFile();

        }catch(Exception e){
