Below info you can use.
- Create a servlet that manages a list of locked documents.
- When you edit a document add it to the locked document list and will be removed it from there after 10-12 minutes.
- This lock can be renewed. So when you edit a document you would request a lock, then run a CSJS timer code that would call the function to invoke lock for next 10 minutes every 10 minutes
- When there is a save call the unlock function (unless you stay in edit mode).
- Here if a user closes the browser, after 10-12 minutes the document will automatically be unlocked.
- You can implement the locking function, using user's id-location or any other specific information.
