B4J Question User interface with non-ui server

[derez]

It sounds a contradiction, but -
in the CCTV server I want to use the sendimage response to provide commands to the camera device.
The server is non-ui, so there is no user interface (!)
Is it possible to put some button on the html and then pass its action/status to the sendimage for response ? I don't see a feedback from the getimages to anything but the html page.

Edit: I learned how to make a button but what should I put as its action ?

 resp.Write("<form action=???>").Write("<input Type=button value=Something>").Write("</form>")

The browser calls GetImages (from the ajax query in index.html).
