Thanks for the tip. I've inserted the following between the load and
save - it appears to work:
XTextFieldsSupplier supplier = (XTextFieldsSupplier)
UnoRuntime.queryInterface(XTextFieldsSupplier.class, document);
XEnumerationAccess fields = supplier.getTextFields();
XRefreshable refreshable = (XRefreshable)
UnoRuntime.queryInterface(XRefreshable.class, fields);
refreshable.refresh();
Is there an explanation for why this works?
Thanks,
Tim

also, I believe that user fields themselves support
the XRefreshable interface, so you might just try
refreshing the user fields, instead of the whole
document.

I'm using OpenOffice 2.0.3 to convert ODT byte
streams to PDF from a
servlet.
However, the PDF generation doesn't work correctly
unless I introduce a
sleep() between the call to loadComponentFromURL()
and storeToURL().
Without the sleep(), a blank page is inserted, and
text from the start
of the document is missing.
The source document includes user fields, which
aren't manipulated
during the conversion.
The document is ~8K in size, and I'm using a socket
connection.
From the forum discussion, the issue seems to be
related to the fact
that the document has user fields.
Can anyone confirm if this is a bug, or suggest a
workaround that
doesn't involve using sleep()?
Thanks,
Tim
Conversion code is as follows:
XComponentLoader loader = // get loader
byte[] content = // get
ODT content
XInputStream inputStream = new
ByteArrayToXInputStreamAdapter(content);
PropertyValue[] properties = new
PropertyValue[]{
newProperty("ReadOnly", true),
newProperty("Hidden", true),
newProperty("AsTemplate", true),
newProperty("InputStream",
inputStream)
};
XComponent component =
loader.loadComponentFromURL("private:stream",
"_blank", 0, properties);
Thread.sleep(1000); // required to produce
correct PDF
XTextDocument textDocument = (XTextDocument)
UnoRuntime.queryInterface(XTextDocument.class,
component);
XOutputStreamToByteArrayAdapter outputStream
= new
XOutputStreamToByteArrayAdapter();
XStorable storable = (XStorable)
UnoRuntime.queryInterface(XStorable.class,
textDocument);
properties = new PropertyValue[]{
newProperty("OutputStream",
outputStream),
newProperty("Overwrite", true),
newProperty("FilterName",
"writer_pdf_Export")
};
storable.storeToURL("private:stream",
properties);
outputStream.closeOutput();
byte[] pdfContent =
outputStream.getBuffer();
