Launch PC-application from webapplication (html)

I want to load Word / Excel from a webpage loaded by a webapplication 
running on our Websphere Application Server.

I developed this page in WSAD where it runs ok.  I have a Word_button 
which, when clicked, launches the WordApplication.  However, when I move 
this page to the iSeries it doesn't work anymore. 

Following error is shown:
...
Error: ActiveX component can't create object: 'WScript.shell'
...

This is the html-part
...
<script language="vbscript"> 
        Sub Word_onClick
                runcmd = "file://C:\Program Files\Microsoft 
Office\Office\WINWORD.EXE"
                Set WShell = CreateObject("WScript.Shell")
                WShell.Run Chr(34) & runcmd
        end Sub
        Sub Excel_onClick
                runcmd = "file://C:\Program Files\Microsoft 
Office\Office\EXCEL.EXE"
                Set WShell = CreateObject("WScript.Shell")
                WShell.Run Chr(34) & runcmd
        end Sub
</script>
...
<BUTTON type="button" name="Word" ACCESSKEY="W" style="font-size: 5pt; 
font-family: Verdana">
        <img src="/images/icons/word.jpg">
