Getting PDF annotations in ColdFusion

Question

Currently, I am using coldfusion 9 and I am trying to get information about annotations from within a PDF file.  The problem is that there are two types of annotations: text and popup.  I am using iText and I can get an annotation array that has 7 objects.
<cfset reader = CreateObject("java","com.lowagie.text.pdf.PdfReader").init(expandPath("test.pdf"))>
<cfset pageDict = reader.getPageN(1)>
<cfset pdfname = createObject("java","com.lowagie.text.pdf.PdfName")>
<cfset annots = pageDict.getAsArray(pdfname.ANNOTS)>
So now I see that I have 7 annotations ( I know one is text, and the other 6 are popup). At this point I want to loop through the annotation array and get the informartion
<cfset iterator = annots.listIterator()>
<cfloop condition="iterator.hasNext()">
       <cfset annot = reader.getPdfObject(iterator.next())>
       <cfset content = reader.getPdfObject(annot.get(pdfname.CONTENTS))>
       <cfif not isNull(content)>
               <cfoutput>
               <p>
               Text Comment =#content#    <!--- This works for the text comments --->
               </p>
               </cfoutput>
       <cfelse>
               <!--- This happends to be the Popup contents, and where I get lost ---->
       </cfif>
</cfloop>
So in the part where I am trying to get the popup contents, I have tried <cfset x  = reader.getPdfObject(annot.getAsDict(pdfname.popup))>  This works, but I can't seem to extract the data.  All I need is to get either the Subject or Name from the popup innotation as they are set to a set number of possibilities in our system.  How do I extract the name or subject info drom the popup object?

Thank you!  I had been trying to get the subject off of the annot obj.  I didn't realize that the I had to init Subj.  Once I tried that I was able to do annot.get(subjKey).toString() and get the values I needed!
Thank you again!
