Changing to docker and receiving Illegal mix of collations (latin1_danish_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation ‘=’ error

I am atempting to change our application from a server to a docker on a virtual machine. We are using mysql for data, and tomcat (spring) for the gui. It seems to work well in the docker, execpt for when a stored procedure is called. It gives the error message:

Request processing failed; nested exception is java.lang.RuntimeException: java.sql.SQLException: Illegal mix of collations (latin1_danish_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '=' 

This error message does not occure when the application is run on the server (not the docker version), so I am asuming there is some configuration that I have not been able to transfere from the original application to the docker based application. Since it works with the same data on the server, I don’t think it should be nessesary to change the tables or the procedure.

The docker creates a mysql:5 container and a tomcat:8 contaner and they comunicate thru a docker network. The GUI connects with the database with this line:


I have only changed ‘localhost’ to ‘db’, as tomcat and mysql are on sepperate containers on the docker version. I have tried a few variations of characterEncoding, like latin2, but with no luck.

I have been loking at the config files in /etc/mysql/ but I haven’t found anything that seems relevant.

Does anyone know what settings I have been missing, or what more I can do to futher narriate the problem. I am new in this line of work, and is learning myself bouth docker and mysql while working on this transfer.
