How to open a file throught specifcly software?

Question

Hi all,
I pretend to open a file that is already check in on content server throught some software.
For example, a *jpeg file is check in on content server and then I want to be able to open this file directly with photoshop.
I know that the service GET_FILE opens some files (txt, docs, etc) but how can I customize specifcly softwares to do it?
Thank you,

if i am not mistaken, COAO still uses the OS mechanism to invoke the associated native application and that only supports one way of opening a particular filetype (well, technically there are two, the native app and the "choose application" option).
one possible way of doing what you are looking for, is to use custom protocol handlers. a protocol handler is the piece of code that gets invoked by the browser framework to handle a particualr URL. most browsers have built-in handlers for http, https and ftp, but you can extend the list yourself. so basically you would create a handler for each app you want to invoke or you would create a universal handler that chooses itself.
most messaging clients, btw, use this technique to allow you to create links on a webpage. what you would have to do then is to customize UCM to generate this particular URL in the action menu. (e.g. photoshop:/my/path/via/web/dav.jpg) the photoshop: part would then trigger your custom handler which would then simply invoke the associated application.

in any case, you will have to do some custom coding, if you want to go above and beyond what the operating system gives you.
hope this helps,
