By using this method
public boolean saveAs(Shell shell) {
          FileDialog saveDialog = new FileDialog(shell, SWT.SAVE);
          saveDialog.setFilterExtensions(new String[] { "*.xsd;", "*.*" });
          saveDialog.setFilterNames(new String[] {
                    "XML Schema Definition (*.xsd)", "All Files " });
          saveDialog.open();
          String name = saveDialog.getFileName();
          if (name.equals(""))
               return false;
          if (name.indexOf(".xsd") != name.length() - 4) {
               name += ".xsd";
          File file = new File(saveDialog.getFilterPath(), name);
          if (file.exists()) {
               MessageBox box = new MessageBox(shell, SWT.ICON_WARNING | SWT.YES
                         | SWT.NO);
               box.setText("Save As");
               box.setMessage("File " + file.getName() + " is already exits "
                         + "\n" + "Do you want to replace it?");
               if (box.open() != SWT.YES) {
                    return false;
          this.file = file;
          this.saveToPath = saveDialog.getFilterPath();
          return save(shell);
     public boolean save(Shell shell) {
          if (file == null)
               return saveAs(shell);
          Cursor waitCursor = new Cursor(shell.getDisplay(), SWT.CURSOR_WAIT);
          shell.setCursor(waitCursor);
          FileWriter fileWriter = null;
          try {
               fileWriter = new FileWriter(file.getAbsolutePath(), false);
               fileWriter.write(text.getText());
          } catch (FileNotFoundException e) {
               displayError("File_not_found " + file.getName(), shell);
               return false;
          } catch (IOException e) {
               displayError("IO_error_write" + "\n" + file.getName(), shell);
               return false;
          } finally {
               shell.setCursor(null);
               waitCursor.dispose();
               if (fileWriter != null) {
                    try {
                         fileWriter.close();
                    } catch (IOException e) {
                         displayError("IO_error_close" + "\n" + file.getName(),
                                   shell);
                         return false;
          return true;
     }
