Java API for comparison between two word files

Hi Folks,

I have requirement in which I need to compare two word files and display comparison results in browser with differences highlighted.

Word file is around 20 pages long, contains tables,images and input fields like text box, check box and drop down, user is allowed to delete paragraphs and add new paragraphs into word file.

I have tried using Apache POI and DOCX4J but it did'nt help to produce accurate results.

Please let me know what is the best way to do it.

Thanks !
