How to check if a file exists in Web Dynpro

Dear experters:

I have a business requirments which is to check if a file exists both in local PC and application server using web dynpro.

I have founded a FM DX_FILE_EXISTENCE_CHECK to do it. But it seems that it doesn't work in web dynpro when I used it to check a local file in my PC. the Exception 'FRONTEND_ERROR' of the FM was always throwen.

I don't know why it did. may I get any suggestion from you or give me some other solution to do it?
