Problem in editing the custom properties of Office 2007+ files.

[Rahul Dev Vardhan <ra...@newgen.co.in>]

We are editing the custom properties of a document as mentioned in the below code,

      FileInputStream fis = new FileInputStream(sourceFile);
        POIFSFileSystem fileSystem = new POIFSFileSystem(fis);
        fis.close();
        DirectoryEntry entry = fileSystem.getRoot();
        
        DocumentEntry siEntry = (DocumentEntry) entry.getEntry(SummaryInformation.DEFAULT_STREAM_NAME);
        DocumentInputStream dis = new DocumentInputStream(siEntry);
        PropertySet isPropertySet = new PropertySet(dis);
        dis.close();
        SummaryInformation si = new SummaryInformation(isPropertySet);
        
        DocumentEntry dsiEntry = (DocumentEntry) entry.getEntry(DocumentSummaryInformation.DEFAULT_STREAM_NAME);
        DocumentInputStream ddis = new DocumentInputStream(dsiEntry);
        PropertySet disPropertySet = new PropertySet(ddis);
        ddis.close();
        DocumentSummaryInformation dsi = new DocumentSummaryInformation(disPropertySet);
        CustomProperties properties = dsi.getCustomProperties();
        if(properties == null) {
            properties = new CustomProperties();
        }
        properties.put("ImgdDocumentOraseq", "47384378");
        dsi.setCustomProperties(properties);
        si.setAuthor("RD");
        si.setComments("78787877");
        si.write(entry, SummaryInformation.DEFAULT_STREAM_NAME);
        dsi.write(entry, DocumentSummaryInformation.DEFAULT_STREAM_NAME);
        FileOutputStream os = new FileOutputStream(sourceFile);
        fileSystem.writeFilesystem(os);
        os.close();

It works fine for .doc, .xls and .ppt files, but i am not able to implement the same functionality for .docx, .xlsx and .ppts files.

Please let me know your comments regarding the same.

Thanks & Regards,

Nope, the OOXML file formats use a very different container, and 
properties are stored in a totally different manner

The usermodel classes for DOCX, XLSX and PPTX all extends from 
POIXMLDocument which provide a way to get at the properties. (Alternately, 
you can just create a POIXMLProperties class for a OPCPackage). From this, 
you can get at the various kinds of properties, and read/write/add them

I'm not sure if we have any examples for writing them (and if not, please 
do submit an example when you're done!). We do have a good example for 
reading though, in the form of POIXMLPropertiesTextExtractor
