Creating MS word document using FolderFontSource

Hi
I want to create a word document using only the font(s) in a folder. I copied all the Arial fonts to a folder and tried to create a word document using FolderFontSource. I see that the document that got created has the text in Times New Roman font.
Please see the code below-

FolderFontSource folderFontSource = new FolderFontSource("C:\\weblogs\\font", true, 0);   	 
Document doc = new Document();
doc.setFontSettings(new FontSettings());
doc.getFontSettings().setFontsSources(new FontSourceBase[]{folderFontSource});
DocumentBuilder builder = new DocumentBuilder(doc);
builder.write("Testing Font");
doc.save("C:\\weblogs\\WorkingWithFonts.docx");

Can you please help me create a word document with only the fonts I copy to a folder or load to the memory using MemoryFontSource ?
Thanks
