hello

i tried to update custom properties of a remote xlsx document, which is located
in a local network, via outputstream.

after writing the file, i can't open it, because some parts seems to be
damaged.

here is the code:

        OPCPackage opcpackage = OPCPackage.open(file.getAbsolutePath());

        POIXMLProperties props = new POIXMLProperties(opcpackage);
       
org.openxmlformats.schemas.officeDocument.x2006.customProperties.CTProperty
property = props.getCustomProperties().getUnderlyingProperties()
                .addNewProperty();
        property.setName("FileID");
        property.setI4(123);

        // props.commit();
        XSSFWorkbook workbook = new XSSFWorkbook(opcpackage);
        FileOutputStream out = new FileOutputStream(file);
        workbook.write(out);
        opcpackage.close();
        out.close();

thanks
waldek
