Can you please copy the request as cURL and paste it here? Just want to make sure what url are you hitting. is it for real the localhost?

i build a vmware workstion env to runing all apps,include java app\python app and nginx,and via chrome with my windows host to access nginx on the vmware.btw,i runing a centos 7.2 to runing apps,and disabled selinux and firewalld.
so i can't paste a url in here.
thanks for your replay.

I've got the same issue during pressing "SEND" button on UI

docker logs of java container:

before it I run

docker run -d -p 8080:8080 \
  -e SA_LOGIC_API_URL='http://localhost:5000' \
  rinormaloku/sentiment-analysis-web-app

docker ps:

@itsNikolay I surmise that the Java and Python containers are not put in the same network.

A simple approach would be to get the Container IP of SA-Logic and use that instead of localhost

docker run -d -p 8080:8080 -e SA_LOGIC_API_URL='http://<container_ip or docker machine ip>:5000' $DOCKER_USER_ID/sentiment-analysis-web-app 

Use Docker Machine IP if you are running Docker in a VM (classic docker setup) otherwise if you have Docker for Windows (with Hyper-V) you need the container IP.

Further explanations are in the following file sa-webapp/README.md

Sorry for the late response, and thanks for asking :)
