Opening a docx document in Word from a browser

i have a primefaces webapp running on a glassfish server, which has a specific section used to manage word documents.

In this section the user can see his documents and add information relevant to the system to it, and also replace a document.

What i'd like to do is make a button that would open ms word on the user computer, downloading a given document, without needing to:

• make him download the docx


• make him open it manually


• make him unlock the document for editing (since it was downloaded from the internet it will be locked).

Is there a way i can do that directly? This must be compatible with chrome, firefox and IE (at least the latest versions)

Thanks!
