HCI: How to create a stage plugin that includes a closed source JNI with multiple .so files?

Hello Community...


I'm looking to develop an HCI stage for converting scanned documents into text-searchable documents using OCR software.


It's been suggested I use ABBYY's finereader which seems to work well.


So far, I've successfully used their SDK to produce a stand alone app that converts a single tif document into a text-based PDF.


I'd like to migrate that code into a Stage... and I've had some limited success.  I was able to create a jar that includes the ABBYY wrapper and can execute via the plugin test harness.


However, I need LD_LIBRARY_PATH to point to the mountain of shared library objects (.so files) so that the underlying JNI function may dynamically link to these .so's.


I should note, I'm not loading the .so's myself.  They are loaded implicitly by the ABBYY wrapper jar.


The other issue I have relates to process(), but I'll save that for a separate question.


If there is no good way to do this, one idea I've had is to take the closed source JNI and wrap it into a tomcat/docker container and essentially provide a RESTful micro service interface to the ABBYY SDK.



Thanks in advance!
