Vaadin 6 and 7 side-by-side in same application ?

Vaadin 6 / 7 / 8
1

Hello,

we have a rather large project with part sin JSP, part sin Vaadin 6 and are now wondering if we can add new parts with vaadin 7 ?
Or is it not possible to have vaadin 6+7 in the same web application (war file) ?

You cannot mix the versions in the same WAR file as the WAR has a common classpath and having Vaadin classes there twice would cause problems.

You might also have problems with Vaadin 6 and 7 applications on the same page (initialization, conflicting themes and more).

It’s what I feared,

but thanks for the confirmation
