WebApp not working on Virgo

General

Hi,

after having lots of trouble with vaadin working together with the equinox servlet bridge I’m now trying to run a simple vaadin app on eclipse virgo.
The app is running fine on tomcat but on virgo I get the following error:


[size=1]
javax.servlet.ServletException: Error instantiating servlet class com.vaadin.terminal.gwt.server.ApplicationServlet

The app is the “hello world”-App from the vaadin tutorial.
So why is the ApplicationServlet not found?

[Edit]
I found out, that the directory $VIRGO_HOME$/work/Catalina/localhost/HelloVaadin is empty. Shouldn’t the content of the war be in there?

This
 solved my Problem.

But to me this is a Bug in Virgo because they are referring to WAB Errors in the manifest file but WAR != WAB. So there must be an error when they convert WARs to WABs internally.
