How to execute xpdf from within an html menu?

From the command line I can type: xpdf filename.pdf to view a pdf file. 
Is there a way to execute xpdf from within an html menu? 
For example with a link similar to these two (which don't work ;)): 
    <a href="xpdf  filename.pdf">view filename.pdf</a> 
    <a href="exec xpdf  filename.pdf">view filename.pdf</a>
