Vaadin 7.7.13

Vaadin 6 / 7 / 8

Our current application that uses Vaadin 7.7.13 started to present a problem in production, displaying the message below, in the development environment in Eclipse it works very well, only when we build “mvn compile package”, we generate the War and we deploy in Tomcat is that the message appears and the application does not work.

Failed to load the bootstrap javascript: ./VAADIN/vaadinBootstrap.js?v=7.7.13

This month we started migrating the application to the latest version of Vaadin, but we need to keep the current version running just for bug fixes.

To give us an idea of what might be causing this?

You should check the server logs, and maybe the network tab and JavaScript console in the browser.

Now it has the same message also in the development environment

The question is why did this start to happen, what is it configured wrong, we can’t identify the cause

9

Is it possible to connect remotely to check the configuration of our project?

10

Sounds like a job for commercial Vaadin support.
