read and split pdf doc on i5

I am assuming others are receiving pdf files that need to be processed on 
iSeries.

Receiving a 1,000 page pdf file containing text and images. Each page relates
to a single invoice. The index contains a unique code for each page that I need 
to extract.
Each page needs to be split into a separate pdf file, with file name related to 
that unique code.
Each file is password protected (and is labelled "customer key for decrypting").
Inside file, is labelled PDF-1.4 (although I prob need to support later 
versions)
Would like to split this file and move individual pdf files to their proper 
directory in a 
batch process to execute when file downloaded via ftp. 
I have found java tools on Source-Forge that may work, but not familiar with 
java, and have
never loaded a java tool to iSeries. Need to be able to call java tool from 
RPGLE.
Found some unix tools, but they could not process encrypted file.
Many interactive products, but hoping not to go there (although this may become
an interactive process for the once a week download  and split this file).
