How to deploy existing project to Google App Engine?

Hi,

I’m trying to deploy an existing vaadin project to GAE.
But I’m constantly getting an error:
ClassNotFoundException: com.vaadin.server.GAEApplicationServlet

This is what I’ve done:

  • commented out the @WebServlet annotation in my UI class
  • projec properties, checked: use Google App Engine. Thereby some libraries were added to my WEB-INF/lib folder: gwt-servlet, jsr107, some appendine-*.
  • created the appengine-web.xml
  • I’m using latest v7.1.1
  • created the web.xml:

	<servlet>
		<servlet-name>MyProject</servlet-name>
		<servlet-class>com.vaadin.server.GAEApplicationServlet</servlet-class>
		<init-param>
			<param-name>UI</param-name>
			<param-value>de.mypath.ApplicationUI</param-value>
		</init-param>
		
	    <init-param>
	      <param-name>widgetset</param-name>
	      <param-value>de.mypath.MyWidgetSet</param-value>
	    </init-param>
	</servlet>

	<servlet-mapping>
		<servlet-name>MyProject<</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>

Where could this exception come from?

It’s called GAEVaadinServlet.
