Trusted function not reffered in PDF file - Adobe reader.

Question

Am failry new to Adobe scripting.
I am trying to generate a jasper report of PDF file format from an online web application
MY intension is to automatically save the generated report into my user's hard drive location say /C/Sample/sample.pdf
I have created the trusted function and made it copied to the folder C:\Program Files\Adobe\Reader 11.0\Reader\Javascripts
Trusted function code mySaveAs.js
var mySaveAs = app.trustedFunction( function(oDoc,cFile)
app.beginPriv();
// Ensure path has trailing "/" cPath = cPath.replace(/([^\/])$/, "$1/");
try{
  oDoc.saveAs(cFile);
}catch(e){
  app.alert("Error During Save");
app.endPriv();
And am invoking the script from the Jasper api which will be a part of the PDF script like below
exporter.setParameter(JRPdfExporterParameter.PDF_JAVASCRIPT,
     " if(typeof(mySaveAs) == 'function') { " +
     " mySaveAs(this,'/C/Sample/sample.pdf');"+
     " } else { " +
     " app.alert('Missing Save Function\n Please contact forms administrator')" +
its just Equivalent of
if(typeof(mySaveAs) == 'function') {
      mySaveAs(this,'/C/Sample/sample.pdf');
} else { 
  app.alert('Missing Save Function\n Please contact forms administrator')}
but am not able to get the file saved in my client machine.
Kindly suggest me a better approach or any where if am missing something.

Am currently using Adobe reader 11 I am not getting any alert .
But the same saveAs() works well in XP even with out making it as a trusted function, We have just placed the script inside the PDF itself. But its not working in Windows 7.
Below code works fine in Win XP
try
     this.saveAs('/C/Sample/sample.pdf'');
    catch(e)
    { app.alert(e);}
