Deployment of SmartSync Application

Hi,

I have a problem with deploying an application. I uploaded the .war-file of a smart sync project to the ME web console. I assigned this application to a user and after synchronizing the user can see the folder in his local \webapps directory. But after restarting the mobile engine on his device, he can not see an entry with the apps name. What problems can cause such errors?

Is it rather a problem with ME web console or the Mobile Engine?

Thanks for your help,

Dominik
