Document locking in xPages

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.

SSJS library functions in xpages

Create a SSJS script library:
Code-Script Libraries-New Script Library-Provide name and select type "Server JavaScript".

Create function in the library:
function testFunc(){
// your code goes here
}

In SSJS you are not required to define the parameters while creating function, you can write function below way and decide how many parameters you want to pass later.

Add this script library in your xpage
Open xpage-Resources-Add-JavaScript Library-Select library and click OK

Now you can call this function with your parameters or without parameters.
testFunc();
testFunc(Param1, Param2, Param3, Param3);

If you wish to access these parameters in your function you have an array with all the values available in order, name of the array is arguments.
You can find value of the first parameter Param1 in arguments[0]
second parameter Param2 in arguments[1]
and so on..

This is my first attempt on this, i will keep improving this.
You can also help me for the same. Thanks for reading.
