No UIProvider returned a UI for the request. local GAE

using 7.0.4

I followed this thread!/thread/2442343 to get over the first set of problems.

and then

this thread!/thread/2800528/2800527

which basicly said

The second problem (and this is the one that caused the UIProvider exception running locally) is a result of the development server trying to serve static files from a jar. The delivery includes two such jars (themes and widgetsets). The GAE wiki indicates that serving static files and be a performance problem, in fact when running locally it cause this problem. My solution was to un-jar the themes and widgetsets. You also need to add an entry to appengine-web.xml to point to the static files Something like this:

which is a bit vague, I found this

It is recommended (but not mandatory) to extract themes and widgetsets and have App Engine server these statically. Extract VAADIN folder (and it’s contents) ‘next to’ the WEB-INF folder, and add the following to appengine-web.xml:

       <include path="/VAADIN/**" />

so I did all this stuff, I think correclty

cus, I can force this to happen by removing some of the contense of the un - jared


cant find a wigitets one ?

INFO: Requested resource
[/VAADIN/themes/base/common/img/loading-indicator.gif] not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.

So how to make a Vaadin 7.0.4 project work with Google App Engine on the local machien ???

any help would be great cus now I have know Idear.


I have the same problem and haven’t got the solution yet.
