Return binary files in/outside the page in an Action

[Liang Fang <li...@indiana.edu>]

Hi,

I would like to program an Action class to download some binary files.
However, it is obvious that the returned binary stream should pop up
another new window, instead of getting into the same page. Is there any
way to do so in an action class? 

Furthermore, if I want the returned binary file to be embedded in the
page, say an image, how to do that? The AbstractPortlet API setContent
methods only allow String or ECS ConcretElement objects, which are for
text display.


Thanks!

Liang
