To pass handle of window(frameset) in which pdf is opened.

Yes and No. You can pass strings into a PDF from JS on an HTML page. So you could pass in the Window Name. The only way to open a URL from Acrobat into a named window is to use JavaScript in the URL. Is this what you are doing?

Take a look at this example:

thanks thomp.
But the solution didn't work. Well let me put in different way.
I have a website thru which I open a pdf. Pdf is opened in a framset so that I can get its handle while opening it. In that pdf there is a link(of the same site, having some deviations). I can open multiple pdf frm that site.

Now the objective is, whenever, I click on a link present in pdf, it should get open over that window itself(that means a new window having behind window as a pdf).
And in my case it is opening over the last pdf window.
The reason behind it is that the latest pdf handle is present with me and all other handles are lost.

I tried on window.focus event to get the handle(self) but it didn't work for windows in which pdf gets opened.
Then I tried to open the pdf link thru ur solution, it didn't work.

The concern is why i dont get window.focus event activated when pdf is opened in the frameset.

I don't know the specifics of this kind of interaction between the browser and Acrobat. I think you need to do a lot of experimentation to see how all this works.

Good Luck
