You should be able to get the temp file directory by adding something like
this to the code which is executed by the Tomcat server:
File outputfile = File.createTempFile("test", null);
String temporaryFileDirectory = outputfile.getAbsolutePath();
That'll return whatever the O/S defines as the temporary directory (e.g.
/tmp in Linux, C:\Users\YourUserName\AppData\Local\Temp for Windows).
Check to see what returns when running the code from within Tomcat and
then check the permissions for that location and it should take care of
it. If you are running Tomcat in a development environment, it's probably
running under your user ID, so just see if you can create a file in that
directory. I've used the merge function from Tomcat before, so it's
probably just a little server setup which you need to do.

Yes, PDFBox tries to create a temp file but it can't. You have to define
some
kind of a temp space and that temp space has to be writable for your
application.
