GWT example broken when using GAE

[Donatus]

Hi,

I've been trying to conjure a ROO script that will provide a GWT/GAE example. Based on the expenses sample, I have the following script.

project --topLevelPackage org.springsource.roo.extrack

jpa setup --provider DATANUCLEUS --database GOOGLE_APP_ENGINE

entity jpa --class ~.server.domain.Employee --testAutomatically
field string --fieldName displayName --notNull

web gwt setup
web gwt all --proxyPackage ~.client.proxy --requestPackage ~.client.request

logging setup --level INFO

(The only differences between this and the expenses example is the dataneucleus jpa setup and the much simpler domain model)

The problem is that when I do "mvn clean gwt:run" I get the following error...

[ERROR] java.lang.ClassCastException: com.google.appengine.tools.development.ApiProxyLocalImpl cannot be cast to com.google.appengine.tools.development.ApiProxyLocal

Does anyone have a script that can produce a working example of GWT + GAE with Roo?

I'm running the latest git revision 99550cf42e22c53012fa8d1867989c12534c9577 of Roo (clone taken on Dec 29/2011) which I've built from source.

Thanks,

I encountered the same problem here. Anyone got it work?

[khuevu]

I get it work by removing three jars file from the target folder:
appengine-api-labs
appengine-api-stubs
appengine-testing
