How to open file from UNIX server?

Hi everyone,

Now I want to get file (like PDF, Word) from UNIX server and open it.

I mean, open directly from UNIX server and start Acrobat Reader or Microsoft Word and show the file, not by download to my own local PC.

I know the solution using the method "cl_gui_frontend_services=>execute"  to download to PC and open file.

Please tell me how I can do it...

Thanks.
