In one of our project we were asked to check a few dozen PDF documents for consistency. So we needed a way to cross-reference the documents and find keywords. At the time there was no SimpleGraph project yet and we created a special solution and made it available as OpenSource.

Using in Docker

In Issue #4 peebles asked how the example would be run in a docker container.

Start an OpenJDK8 container mounting the pdfindexer directory

# get a fresh version of the PDF Indexer
git clone https://github.com/WolfgangFahl/pdfindexer
# change to the directory
cd pdfindexer
# run a docker Container with OpenJDK Java 8
docker run --rm -it -v $(pwd):/deploy -w /deploy openjdk:8 bash
