Hello,
The problem I am facing is while using option 1 where we need to add a feature LENSID manually into the custom created documents. I fetched feature schema that also did not include LENSID in the list. What am I missing if just updating this list is sufficient? I followed the process below but that gives a nullpointer exception when trying to add LENSID. We have implemented a GATE plug-in with a custom IE application that is working fine. That adds NEAR_TOKENS feature automatically in the documents according tour custom logic. This works fine when we add documents using populator.

As long as all things that the code above does happen in the populator tool JVM, you can't modify any object there. In order to be able to set your custom property, you have to add another step to the annotation process. That process is controlled by a special file: kim-home/context/default/resources/IE.gapp (by default!). This is the description of our GATE application; in short, GATE is a platform for text analysis and similar stuff, developed by our colleagues at the University of Sheffield. See http://gate.ac.uk for more info. If you are not familiar with GATE, I'm afraid it will be much harder to achieve your goal. With a few words - you have to add a new GATE processing resource to the GATE application. That processing resource would actually do the job of setting your custom property to the document. If you need more information, you can always ask us, but it is really recommended that you know how to do things with GATE. Hope this helps!
