OpenNLP Name Finder training: Unsupported language: en

[Xiang Ji]

Hi,

I’m trying to test training OpenNLP’s Name Finder on some data, 
according to the guide in the documentation. However, I encountered the 
error: |Unsupported language: en|, which doesn’t seem to make any sense.

The command I ran is: |opennlp TokenNameFinderTrainer.conll03 -model 
model.bin -lang en -types per,loc,org,misc -data train.txt -encoding UTF-8|

I downloaded OpenNLP 1.9.0 from 
https://opennlp.apache.org/download.html. The |OPENNLP_HOME| environment 
variable does seem to be properly set, and the |lang| folder in the base 
folder contains an |en| folder.

Best regards,

Xiang Ji
