Merge Pdf documents

Hi Team , I have a requirement in my application where I have to merge around 100 pdf in one . As the current java function that is available right now is capable of merging  only 10 pdf . Do you have any other solution by which I can merge 100 pdf .

You can try to create a java action yourself. I assume the java action is limited due to performance considerations.

What you could possibly also do (this is a dirty solution) is that you do it cumulatively. So merging 1 - 10 to file 1 and that again merge with 11 - 20 and create file 2 and so on.
