[amisevsk]

Describe the bug

The current java-mysql devfile and sample project build and run successfully, but on attempting to do any database operations in the app, an exception is thrown:

Che version

• latest
• nightly
• other: please specify

Steps to reproduce

1. Create workspace: [che-url]/#/load-factory?url=https://raw.githubusercontent.com/eclipse/che-devfile-registry/master/devfiles/java-mysql/devfile.yaml
2. Use the maven build task
3. Use the run webapp task
4. Navigate to e.g. "Find owners" and attempt to "find" an owner

Expected behavior

Webapp should connect to database as expected

Additional context

[svor]

The problem is that the "petclinic" database has to be exist with all tables for the app to work but it doesn't. To create it I added a new command to execute sql script (the script is already prepared in the project) which creates "petclinic" database and all necessary tables, but I got a problem when tried to execute mysql command in mysql container, the problem is described here: #13416

[sparkoo]

I'm getting this error https://gist.github.com/sparkoo/37d1f38811a24507ddf119f00bfa044d

[svor]

@sparkoo could you please clarify when did you get that error. Is it still reproducible with this PR: eclipse-che/che-devfile-registry#51?

[sparkoo]

@svor I get this error when running run webapp task. Your PR don't fix it for me. It's the same. I ran prepare database and maven build first.

[svor]

@sparkoo I can't reproduce this problem.
As I see @amisevsk also tested this devfile with my changes and he didn't find any problems eclipse-che/che-devfile-registry#51 (review).

[tolusha]

I've just checked and everything works fine.

[svor]

I'm going to close this issue since eclipse-che/che-devfile-registry#51 was merged.

[sparkoo]

@svor I've tested again. It works on minishift, but is still failing on minikube for me. How do you run Che here?

[svor]

@sparkoo I tested it on minishift

[svor]

@sparkoo I'm going to check it on minikube

[svor]

It works on Minikube on my side as well: https://youtu.be/vGqQDdcEd5U
Minikube version: v1.2.0
eclipse/che-server:nightly
eclipse/che-theia:7.0.0-next
