I have copied code I located on cfsearching for concatenating pdfs and including any existing bookmarks ( http://cfsearching.blogspot.com/2007/12/getting-started-with-itext-part-17.html ), have purchased the iTextinAction book, but am stuck when trying to add a new bookmark. I keep getting the message '

java.util.ArrayList cannot be cast to java.util.HashMap.

I suspect I am not adding my own 'custom' bookmarks to the list of existing bookmarks correctly. I tried changing the list of existing bookmarks from an explicit vector (this was how the example was written) to an array instead, but still have this issue when I try to close my document. Following is the code I have modified. I would appreciate any help. I am not a Java programmer and am really struggling to understand how this works and how to make changes to it.

       outlines = arrayNew(1);
     arrayAppend(outlines, 'Pirate Jack');

      for ( fileIndex = 1; fileIndex LTE arrayLen(arrayOfInputFiles); fileIndex = fileIndex + 1) {

      }
