Question

Currently we use OpenOffice to grab bookmarks in a template file document and replace them with content from our DB via Java. The lines of code that actually save the file look like this…

  XStorable storable = UnoRuntime.queryInterface(XStorable.class, document);


        // Save as Word 97 Document
        PropertyValue[] properties = new PropertyValue[1];
        PropertyValue property = new PropertyValue();
        property.Name = "FilterName";
        property.Value = FORMAT_WORD_97;
        properties[0] = property;
        storable.storeAsURL(saveFileURL, properties);

We want to directly write the file to the servlet response outputstream, does anybody know of a way to directly get the document as a byte array or inputstream via OpenOffice’s UNO api in Java?

Answer 1

This depends on the implementation of the UNO API. We were able to do this with PDF,

    OutputStream os = response.getOutputStream();

    PropertyValue[] properties = new PropertyValue[2];
    PropertyValue property = new PropertyValue();
    property.Name = "FilterName";
    property.Value = FORMAT_WORD_97;
    properties[0] = property;
    PropertyValue streamProp = new PropertyValue();
    streamProp.Name = "OutputStream;
    streamProp.Value = os;
    properties[1] = streamProp;

    storable.storeAsURL("private:stream", properties);
