Issue with Deploying WAR to TOMCAT

General

[b]
Hello All,

Thank you for your help.

We are currently trying to migrate our web UI to tomcat. When we upload the war file and navigate to the page we get the message below:

when we compile with mvn using mvn tomcat:run the UI displays fine. But when we compile using mvn tomcat:run-war it fails and we get the same message below.

Not sure if this question is related but, is there a reason why there is no maven com.vaadin 7.0.0.rc1. Thank you

Maybe you have multiple versions of some JARs on the classpath (e.g. in the WAR and/or in a shared library directory on Tomcat) and there is a conflict between them.
