Hi,
i want to know if the following is possible:
in my HTML/JavaScript form, the final output is displayed in a window (say named as 'mywindow'). ie the window.open() and the document.write() functions are used to get the final ouptut. now, is it possible to use servlets to read and/or manipulate the contents of this window (ie mywindow)??
thanks in advance.

You should be able to feed the data from that window back to your servlet like you do with any other form. Assuming it's a form. Similarly if your window is being opened by another form it's contents could come originally from a servlet.

Hi greg,
thank u for the reply but i am afraid i will have to trouble u with one more question:
actually the content of my window is something like:
<choose>
<figure>C:\My Documents\ads.jpg</figure>
</choice>
now can i write a servlet that reads the content of the window and thus extracts the 'ads.jpg' file?

The only thing a servlet can see is a request, such as form submission. However, if your JavaScript is writing the document that is being shown, it can also write the same material to a variable that is submitted as part of a request.
