​ p.s. docker run from https://developer.ibm.com/learningpaths/ibm-mq-badge/create-configure-queue-manager/ works fine

run.log full execution log

The error is 

The TCP/IP listener program could not bind to port number 1414

which implies the you already have something occupying port 1414. If you run docker ps you will get a list of all active containers.

ksiv commented 2 years ago

docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

I removed any other containers, volumes and images. Only one image and one container atm

ksiv commented 2 years ago

My platform is Docker Desktop 4.7.0 (77141) is currently the newest version available. In Linux containers mode Windows 10 Pro

chughts commented 2 years ago

Based on you having had a MQ container running, and you still getting 

The TCP/IP listener program could not bind to port number 1414

and there are no running containers locking 1414, I think you might have hit a Windows / Hyper-V bug.

Based on similar issues raised on other repos, try running these commands.

netstat -ano

This will show any ports in use.

If 1414 isn't mentioned then try running

netsh interface ipv4 show excludedportrange protocol=tcp

that will show excluded port ranges. I suspect that 1414 might show up there.

ksiv commented 2 years ago

netstat -ano there is no 1414 port in there netsh interface ipv4 show excludedportrange protocol=tcp

Protocol tcp Port Exclusion Ranges there is no 1414 port in there

if I reinstall docker container from step https://developer.ibm.com/learningpaths/ibm-mq-badge/create-configure-queue-manager/ and execute compiled test from step https://developer.ibm.com/learningpaths/ibm-mq-badge/write-run-first-mq-app/ javac -cp .\com.ibm.mq.allclient-9.2.4.0.jar;.\javax.jms-api-2.0.1.jar;.\json-20211205.jar com\ibm\mq\samples\jms\JmsPut.java

Ok. localized. this project is not Win compatible. Workaround:

  1. remove symlink called "com" from mq-dev-badge-sample\MQTicketService\TicketGenerator\src\main\java
  2. place there a com folder from mq-dev-badge-sample\MQTicketService\TicketGenerator\com
  3. remove and rebuild docker images and containers

Have fun!

vicglarson commented 2 years ago

Symlinks in java sources? Seriously? What a joke,

ksiv commented 2 years ago

One never knows with maven, I thought it's a new feature. Nevertheless, "listener program could not bind to port number 1414."}" - seems a "proper" behavior. I mean it's a bug irrelevant to this ticket as DEV.LISTENER.TCP works fine at least I see it in the console as working and an example from https://developer.ibm.com/learningpaths/ibm-mq-badge/write-run-first-mq-app/ works, I still getting my lucky numbers - this would not work without any listener.

chughts commented 2 years ago

So the take away is make this repo, windows compatible. I'll close this issue, and raise a specific one.

ksiv commented 2 years ago

@chughts, It would be nice for dev juniors as the idea of the project to get into MQ JMS development and the variety of desktop systems is still dominated by Windows. Thanks a lot!
