Although the OO file format -which is what that article talks about- is structurally somewhat similar to ODF (the family of file formats ODT belongs to), it is a different file format, so I don't think the article will help.
The JODConverter library -which uses OO behind the scenes- may help with his.
Thanks Sir,I have checked JOD Convertor its working fine in converting odt to doc.But the alignment is not the same when we open the doc file in MS- Word.
