Does anyone know how to fix this problem on jboss deployment? java.lang.NoClassDefFoundError : Failed to link com/vaadin/base/devserver/startup/DevModeStartupListener

Did you make a production build? DevModeStartupListener sounds like something that isn’t included in production mode.

(and you should make a production build if you deploy on jboss)

Hi @vital-koala

How do I make a production build?
