Umlaute get wrong when doing an update of a row

Question

I am running a grails V2.3.5 application which i brought to a new server and a new database server.

Migrated data is displayed correctly.

But when I update a row my German Umlaute get strange characters.

When I change the data with a mysql client it is displayed correctly again.

Any Idea what that could be and where i could look at?

Answer 1

I found the problem it was not related to grails. I missed a tomcat configuration in

server.xml

 URIEncoding="UTF-8"

in

<Connector port="8080" protocol="HTTP/1.1"
        URIEncoding="UTF-8"
        connectionTimeout="20000"
           redirectPort="8443" />
