Using 2.0. My web app receives a set of user's .docx files, converts
them to PDFs, and ultimately merges them. All of that is done, but now
I'm adding outlines/bookmarks. I've worked through the "bookmark for
every page" example and made that work, but my bookmarks obviously
need to be a little different. Here's what I've got going now:
Input: a map containing a title, the semantic location/category of the
information, and an input stream representing the PDF.
1. For each item of input, put the title and destination (first page
of the PDF stream) on a bookmark
2. .appendDocument the PDF on to the MASTER pdf.
I have encountered two problems with this that might be helped by some
suggestions as to functions/objects that can help me. For reference,
all the .docx files under consideration are identical.
Problem 1: Since the destination is set with reference to the
un-appended document, it is lost in the process of appending. As such,
the bookmarks are not functional
Problem 2: At some point in this process (not the first or second
item) something closes the COSStream and I cannot .save the result,
although I can tell it has the right number of pages.
What is the better way of handling this process, which would correctly
deal with meta-data (names of sections) and point each bookmark to the
right (final) thing? Basically it's a problem of merging multi-page
pdfs and making bookmarks for each item appropriately.
For those who want to take a gander at the Clojure code, find it here:

The primary function in question is merge-pdfs-memory2.
Sorry, the last time I coded in lisp was 30 years ago. It was a lot of
fun, but it needed a special type of thinking that won't come back right
now. Please create the shortest possible java code that shows the
"problem 2" you're having, and for "problem 1" please upload the two
files that you're merging and where the bookmarks are lost.
