CFPDF populate existing PDF

I have an existing pdf that I did not create.

The pdf has 2 form fields

"myname"  and "yourname".

I need to capture "myname"  and "yourname" in a form and then output those values to the existing pdf and then output the pdf.

Is there a way to write those variables to the pdf and then output the pdf.

Step 1

Form page

User enters "myname"  and "yourname" and clicks submit

Step 2

User clicks link to get the pdf that will contain "myname"  and "yourname"in the appropriate places.

I can use <cfpdf action="merge" to get the pdf to output, but I cannot get my form variables to output.

They just show up blank.

When I try to use this code below to populate the PDF. I get an error

<cfpdfform action="populate" source="C:\websites\...............">
        <cfpdfsubform name="form1">
            <cfpdfformparam name="myname" value="Boris">
            <cfpdfformparam name="yourname" value="Pasternak">
         </cfpdfsubform>
    </cfpdfform>

This error:

The requested template has been denied access to /C:/ColdFusion8/runtime/../lib/cf-acrobat.jar.

The  following is the internal exception message: access denied  (java.io.FilePermission /C:/ColdFusion8/runtime/../lib/cf-acrobat.jar  read)

Any ideas?
