you need to keep the META-INF/manifest.xml consistent with the zip structure.

guess the easiest is to use ODFDOM library, which you can get at

there's some class that can load & store ODF packages and it maintains the manifest automatically for you.

i'm afraid the documentation is currently offline because the project is currently migrating off of ASF infrastructure.
