How do I configure the OpenNLP Brat Annotation Service?

Hi I am trying to get OpenNLP's Brat Annotation Service working with the BRAT annotator. I can get OpenNLP's Brat annotation Service started, with the following command:

bin/brat-annotation-service NameFinderAnnService -serverPort 8999 ~/myNameFinderModel.bin

The server responds with log messages about glassfish and grizzly bears staring on port 8999. Everything appears ok...

On the BRAT annotator side, I have a tools.conf file containing:

[options]
[normalization]
[search]
[annotators]
OpenNLP tool:openNLP, model:openNLP,  <URL>:http://localhost:8999/ner
[disambiguators]

When I try to use my model (Data > Automatic Annotators, openNLP) I get an unknown connection error. Tagger Service OpenNLP returned the error "Errno 111] conection refused". I know the url exists. I can use firefox on the server where BRAT is running open the url http://localhost:8999/ .

****** Edit: I had a typo in my tools.conf file. I fixed the typo, and the error changed to

Tagger service OpenNLP returned the error: 404 Not Found

Am I leaving a step out?

There was a bug in the OpenNLP brat annotation service (v1.8.3). The bug is fixed and will be available in v 1.8.4. There was also a problem with my tools.conf file. I have edited the question to show the appropriate format. I hope it helps the next person trying to connect the BRAT annotator to the OpenNLP annotation service.
