Saving documents using OpenOffice java api throws Exception

Question

FYI / Context: I am running a portable installation of libreoffice on windows 10 (getting the same exception on a mac with normal installation though).

Reading the document

Maybe this is important... I am reading the document through an InputStream, because the other method fails due to a different exception (probably a story for another time).

public XComponent openFileViaStream(File file) throws CommandAbortedException, Exception {
    Object fileAccess = this.componentFactory.createInstanceWithContext(SimpleFileAccessClass, this.context);
    XSimpleFileAccess xSimpleFileAccess = (XSimpleFileAccess) UnoRuntime.queryInterface(XSimpleFileAccess.class,
            fileAccess);
    XStream xInputStream = xSimpleFileAccess.openFileReadWrite(file.getAbsolutePath());
    PropertyValue[] loadProps = new PropertyBuilder().add("InputStream", xInputStream).build();

    return loader.loadComponentFromURL("private:stream", "_blank", 0, loadProps);
}

Writing the document

PropertyBuilder is a utility class that just builds an Array of PropertyValues for ease of use.

public void save(Object storeMe, File destination) throws IOException, MalformedURLException {
    //@formatter:off
    PropertyValue[] propertyValue = new PropertyBuilder()
            .add("Overwrite", Boolean.TRUE)
            .add("FilterName", "StarOffice XML")
            .build();
    //@formatter:on
        
    XStorable2 st = UnoRuntime.queryInterface(XStorable2.class, storeMe);
    

    // already tried
    // st.storeAsURL(destination.toURI().toURL().toString(), propertyValue);
    // st.storeToURL(destination.toURI().toString(), propertyValue);
    // st.storeToURL(destination.toURI().toURL().toString(), propertyValue);
        
    st.storeAsURL(destination.toURI().toString(), propertyValue);
}

The exception

I couldn't find a solution while searching on stackoverflow...

I really have no idea what I am doing wrong. I've looked at examples from api.libreoffice.org etc. Am I missing something? A PropertyValue?

Thank you in advance!

See if any of these ideas help.

• The URI should look like file:///E:/test/abc.odt .

• Set the filter name to StarOffice XML (Writer) or writer8 . Or don't set it at all; pass one property instead of two.

• Verify you have the authorization to write to the file, for example by using standard Java libraries to create a file in that location. Be sure the file is not locked by some other process.
