DFS - help with streaming a pdf/tiff document to the browser using UCF

I have a DFS 6.5 .NET web application that queries the repository and returns a list of object ids of documents I'd like to display as hyperlinks. When the user clicks a link, I'd like to stream the file to the browser (which will always be IE). I now believe I need to use those object ids to return DataObjects representing the documents, but I'm not sure how to construct the code to create the urls and stream the file once the hyperlink is clicked. The majority of the docs will be pdf or tiff images, so some sample code for either of those formats would be greatly appreciated.

I'm assuming I'd have to set the ContentTransferMode to UCF. I couldn't find any good examples in the DFS 6.5 dev guide or sdk.

Thanks in advance!

Hi,

You can get an url to the content which is streamed through ACS (Accelerated Content Services). The URL is valid for a fixed amount of time, I think it is 5 minutes. So the best way is that to create a javascript link with the objectId passed in, so when the user clicks it you fire an ajax call to your server.

The server then gets the url with IObjectService.getContentUrls(). You can then open a new window with that URL, or simply return that (I think then the browser decides what to do then: open it as an embedd (PDF), or let the user save it (in case of TIF when the user does not have a TIF viewer plugin in browser).

very detailed answer. objectservice.getobjectcontenturls() is the most direct way of getting urls of the objects.

actually, when you call objectserver.get(), you can get the returned datapackage. you can get the content url by datapackage.getdataobjects().get(i).getcontents(). you can judge the type of the content. when ACS is enabled, the type is UrlContent. you can get url and embed it in the web page.

Any results? Was it working this way? Reward points maybe?
