    I want to open a word file and save it as a pdf file with jacob.
    The code as follow:

    public static void main(String[] args) {
        ActiveXComponent _app = new ActiveXComponent("Word.Application");
       _app.setProperty("Visible", new Variant(false));
      Dispatch documents = _app.getProperty("Documents").toDispatch();
      Dispatch doc = Dispatch.invoke(documents, "Open", Dispatch.Method, 
                            new Object[]{"C:\\Demo.docx", 
                                                    new Variant(false), 
                            new Variant(true)}, 
                            new int[1]).toDispatch();
     Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {
                        "C:\\Demo.pdf", new Variant(false), new Variant(true)}, new int[1]);
    Variant f = new Variant(false);, "Close", f);
    _app.invoke("Quit", new Variant[]{});

    The code run without errors and the 'Demo.pdf' has been generated also.
    However Demo.pdf can not be opened by Acrobat Reader.
    It promted "Demo.pdf is a bad file".

    Give me a while and I should be able to post the code to do this. Sadly, it is not quite as simple as changing the extension!

    This example will only work if you are using one of the more recent versions of Word - 2007 or later - as it relies upon the ExportAsFixedFormat method ( which was added into the application then.

    Anyway, here it is and if you look down into the main() method, you should see how to use it.

    import com.jacob.activeX.ActiveXComponent;

    public class ConvertToPDF {
        private ActiveXComponent oleComponent = null;
        private Dispatch activeDoc = null;

        private final static String APP_ID = "Word.Application";
        // Constants that map onto Word's WdSaveOptions enumeration and that
        // may be passed to the close(int) method
        public static final int DO_NOT_SAVE_CHANGES = 0;
        public static final int PROMPT_TO_SAVE_CHANGES = -2;
        public static final int SAVE_CHANGES = -1;
        // These constant values determine whether or not tha application
        // instance will be displyed on the users screen or not.
        public static final boolean VISIBLE = true;
        public static final boolean HIDDEN = false;
         * Create a new instance of the JacobWordSearch class using the following
         * parameters.
         * @param visibility A primitive boolean whose value will determine whether
         *        or not the Word application will be visible to the user. Pass true
         *        to display Word, false otherwise.
        public ConvertToPDF(boolean visibility) {
            this.oleComponent = new ActiveXComponent(ConvertToPDF.APP_ID);
            this.oleComponent.setProperty("Visible", new Variant(visibility));
         * Open ana existing Word document.
         * @param docName An instance of the String class that encapsulates the
         *        path to and name of a valid Word file. Note that there are a few
         *        limitations applying to the format of this String; it must specify
         *        the absolute path to the file and it must not use the single forward
         *        slash to specify the path separator.
        public void openDoc(String docName) {
            Dispatch disp = null;
            Variant var = null;

            // First get a Dispatch object referencing the Documents collection - for
            // collections, think of ArrayLists of objects.
            var = Dispatch.get(this.oleComponent, "Documents");
            disp = var.getDispatch();

            // Now call the Open method on the Documents collection Dispatch object
            // to both open the file and add it to the collection. It would be possible
            // to open a series of files and access each from the Documents collection
            // but for this example, it is simpler to store a reference to the
            // active document in a private instance variable.
            var =, "Open", docName);
            this.activeDoc = var.getDispatch();
         * There is more than one way to convert the document into PDF format, you
         * can either explicitly use a FileConvertor object or call the
         * ExportAsFixedFormat method on the active document. This method opts for
         * the latter and calls the ExportAsFixedFormat method passing the name
         * of the file along with the integer value of 17. This value maps onto one
         * of Word's constants called wdExportFormatPDF and causes the application
         * to convert the file into PDF format. If you wanted to do so, for testing
         * purposes, you could add another value to the args array, a Boolean value
         * of true. This would open the newly converted document automatically.
         * @param filename
        public void publishAsPDF(String filename) {
            // The code to expoort as a PDF is 17
            //Object args = new Object{filename, new Integer(17), new Boolean(true)};
            Object args = new Object{filename, new Integer(17)};
  , "ExportAsFixedFormat", args);
         * Called to close the active document. Note that this method simply
         * calls the overloaded closeDoc(int) method passing the value 0 which
         * instructs Word to close the document and discard any changes that may
         * have been made since the document was opened or edited.
        public void closeDoc() {
         * Called to close the active document. It is possible with this overloaded
         * version of the close() method to specify what should happen if the user
         * has made changes to the document that have not been saved. There are three
         * possible value defined by the following manifest constants;
         *      DO_NOT_SAVE_CHANGES - Close the document and discard any changes
         *                            the user may have made.
         *      PROMPT_TO_SAVE_CHANGES - Display a prompt to the user asking them
         *                               how to proceed.
         *      SAVE_CHANGES - Save the changes the user has made to the document.
         * @param saveOption A primitive integer whose value indicates how the close
         *        operation should proceed if the user has made changes to the active
         *        document. Note that no checks are made on the value passed to
         *        this argument.
        public void closeDoc(int saveOption) {
            Object args = {new Integer(saveOption)};
  , "Close", args);
         * Called once processing has completed in order to close down the instance
         * of Word.
        public void quit() {
  , "Quit");

        public static void main(String args) {
            ConvertToPDF ctpdf = new ConvertToPDF(false);
            ctpdf.openDoc("C:\\temp\\Your Doc.docx");
            ctpdf.publishAsPDF("C:\\temp\\Your Doc.pdf");
