Hi @wajda ,

when i'm trying to access the endpoint (http://spline:9090/consumer), getting below logs in spline gateway rest-server;

13:50:48.994 [http-nio-8080-exec-6] WARN  o.s.web.servlet.PageNotFound - No mapping for GET /consumer

how i can verify that jsp of consumer & producer is present in spline gateway rest-server

Hi @wajda ,

I even tried to setup on docker environment, with the latest version of spline, arangodb image from docker hub, But issue persist.

It appears to be an issue with the image;

Used docker compose file from github;
https://raw.githubusercontent.com/AbsaOSS/spline/develop/docker-compose.yml.

ankit@dockervm:~$ sudo docker ps -a

When tried to access the spline.consumer.url using curl (curl http://localhost:8080/consumer)

[wajda]

You are trying a wrong URL

http://localhost:8080/consumer -- this resource does not exist
http://localhost:9090/consumer/execution-events -- this one does

[dhiraj-raj]

Hi @wajda we tried this URL also i.e. http://localhost:9090/consumer/execution-events , but Spline-UI shows same error message as indicated above.

[wajda]

I have answered it about 3 times already - the consumer REST API URL has to be accessible from the client browser. If Spine UI says "Code 0" it mean it cannot connect to that URL. Please double check your Spline setup.

[ankit302]

HI Wajda,

i understand that, URL is not accessible from splineUI.

we have used same Dockercompose file to run spline WebUI, rest server & arangodb without any modification.
https://raw.githubusercontent.com/AbsaOSS/spline/develop/docker-compose.yml

Do you see ant issue with config parameters in docker compose file ?

Does any one else facing similar issue ?

[wajda]

Ah, that's a new piece of info. Seems like an issue with the Docker. Just tried our docker-compose.yml and the 'spline' container appeared to have connection issues. Re-opening the issue, although I have doubts that it's related to Spline, rather to a Docker network config.

[wajda]

I have just confirmed that it is indeed a particular docker setup issue that has nothing to do with Spline.
I've tested it on three PCs running Fedora, Ubuntu and MacOS, the same Dcoker version 19.03.8. Only on my Fedora PC I have this issue, on the other two laptops docker-compose run Spline with no issue, straight out of the box.
So please check your docker network configuration and consult with the Docker support.
I consider this issue closed.
