Hello,
I have the following error after upgrading to scout 11 on prod.

org.eclipse.scout.rt.platform.exception.BeanCreationException: Exception while invoking @PostConstruct method public void com.scout.app.server.db.sql.DatabaseSetupService.autoCreateDatabase() throws java.sql.SQLException

This is not happening on dev environment, only when deploying to tomcat.
Database for dev is same used with tomcat and they are on same machine.
Does anyone have any idea how to solve this issue.
Kind Regards

Sounds to me if the JDBC driver cannot be found for MySQL. Scout itself does not provide any dependencies to the database drivers because people may use different databases. If you add the MySQL driver as dependency (to the class path) this may help, e.g.

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.23</version>
</dependency>

Hello,
No, that is not the problem, the application was working fine with version 10 and the driver exists like you mentioned, I noticed the issue after upgrading to 11.
Kind Regards

Hello,
I solved the issue by adding
Class.forName("com.mysql.cj.jdbc.Driver");
to the DatabaseSetupService just before calling the driver to establish the connection and it works now.
Kind Regards
