`Could not find class edu.stanford.nlp.pipeline.StanfordCoreNLP` error #1

Closed jimkang closed 8 years ago

After I build and run the image (with the -itp switch), when I go to the corenlp-server directory and try to start the server, I get this error.

root@eeebd23ea63e:/corenlp-server# ./start-server.sh 

> @ start /corenlp-server
> node index.js

Any ideas as to how I can find that class and debug this?

Oh, it seems I missed the "Stanford CoreNLP is also needed. Install separately and make a symbolic link java-lib to it" step and went straight to the "nothing else is needed step."
