My fault, last time I didn't attached one important file to distributed OXT file. This missing file was activtation.jar, which is shipped with Java 6, but isn't with Java 5.
I probably should find it during tests, but my laptop is rather slow, so I prefer not to make anything what will take a lot time [so restarting OpenOffice.org and so on ;-)].
What means "stokrotka"?
It is Polish name for daisy, codename is to official name for my method to avoid mixing files.
It should be able to upload files [without conversion from unsupported format to supported by Google Docs], and to download files, I made also changes to open those downloaded files, but I wasn't yet able to test it.
Download [I'm waiting for feedback]
