Trouble with linking CoreNLP #2

Open jimkang opened 8 years ago

jimkang commented 8 years ago

I'm a little confused about this step:

Stanford CoreNLP is also needed. Install separately and make a symbolic link java-lib to it.

So, I downloaded the stanford-english-corenlp-2016-01-10-models.jar file from that web page and linked it like so:

ln -s stanford-english-corenlp-2016-01-10-models.jar java-lib

After building and running my Docker image, when I try to run start-server.sh from inside the image, I get this error:

root@7d4eb917c470:/corenlp-server# ./start-server.sh 

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

Any ideas about what I should be doing differently?

Doh. It seems I thought the model links were CoreNLP itself.

jimkang commented 8 years ago

OK, if the correct zip file is downloaded, and the directory linked as java-lib, the next problem is that the jar versions are wrong in lib.js. (Currently 3.6.0, is 3.5.2 in the code.)

Sorry for the late reply. Glad you found it out yourself. I haven't touch this code for a long time. Does it work with newer version?

jimkang commented 8 years ago

Well, it does run, but I can't seem to get a response from the http server. (I stopped there a few days ago, so unfortunately, I have no further details.)
