conceptual question: "file download link"? [message #123318]

Folks;

maybe I'm a little off track here, but using RAP I am at the moment trying
to achieve something pretty common in "ordinary" web user interfaces: In
some place (like the cell of a TableViewer) I want to place a functionality
to do a straightforward file download. There's a file provider servlet in
another application somewhere out in our system, and usually I can refer to
(and actually download) arbitrary files via HTTP using this servlet... the
only problem I see so far: How to "emulate" this feature (an HTML hyperlink
that makes the browser access an arbitrary HTTP ressource outside the RAP
context) in a RAP user interface? Ideas, anyone?

TIA and all the best,
Kristian

Kristian,

as of now, there is no "download widget" or similar in RAP.
The browser widget with a mini HTML page that contains only a link
is probably the quickest workaround.
If you need more control over the details, writing a custom widget
shouldn't be too complicated either. In the latter case, feel free
to share your code if you think it might be of general interest.

Hi Rüdiger;

and first off, thanks a bunch for your thoughts on that.

Well this is sort of what I intended to do... Eventually all that is
required in my use case so far would be a hyperlink (like used in the
RCP/IDE or in the RAP mail demo to display the e-mail address) referring to
an HTTP ressource outside the actual RAP application, maybe something like
Eclipse Forms' Hyperlink. Custom "download widget" would be a second option
to consider, I guess...

Cheers & thanks again,
Kristian
