Alfresco node locking in a web script

What I am trying to do is create a set of alfresco web scripts that will allow me to interact with the files in my webproject. I manage to make all the operations of a normal filesystem (list, edit, delete, rename, etc) but i have a huge problem with the lock mechanism. Once someone edits a file in his own sandbox the file must be locked.

Now in the开发者_如何学Go listing of the files, i have access to a method called isLocked() that tells me if a node is locked or not and I can see the owner of the lock as well. These locks were added from the Alfresco default web interface.

And to my question, how can I lock/unlock a node from the a web script ?

Unfortunately there's no Javascript bridge to the LockService, meaning you need to develop a Java-backed Web Script. You will be then able to do something like:

LockStatus lockStatus = lockService.getLockStatus(node);
if (LockStatus.LOCKED.equals(lockStatus) ||
    LockStatus.LOCK_OWNER.equals(lockStatus)) {
  lockService.unlock(node);
}

I guess you can do two things:

1) use the Check-in/out Javascript API Wiki location. If a document is checked-out it will get locked and put in Read-Only mode. And the user can check it in, when he's done.

2) use a Java Backed Webscript with pure Java, you have more control on it. You can lock, unlock etc.
