Unable to run upgraded version of jmix application (2.8.1)

Support

Hi,

I am getting the following error when i try to deploy a jmix application to apache tomcat server: The application was just upgraded from version 2.7 to 2.8.1.

BeanCreationException: Error creating bean with name ‘hubdatastoreEntityManagerFactory’ Failed to read candidate component class: URL [jar:file:/usr/local/tomcat/webapps/app/WEB-INF/lib/atmosphere-runtime-3.0.5.slf4jvaadin1.jar! /org/atmosphere/inject/AtmosphereRequestIntrospector.class]

The ‘hubdatastoreEntityManagerFactory’ refers to a secondary database of the application. In previous version (2.7), the application was running smoothly.

Thanks,

George

Hello,

Did you make sure that the Tomcat version is 10 or greater?
I also got some errors when upgrading, so I recommend first to File - Invalidate caches, all, and then rebuild your war. Gradle clean and vadiinClean.

I don’t work with war at the moment, but would also delete the Tomcat cache, delete the old uncompressed web app folder, and then deploy the fresh war you rebuilt.

Kind regards,
Mladen
