This may be a silly question, caused by my lack of knowledge on platform infrastructure, but I have to know. I have a beautiful web app running in the cloud (acceptance environment) which works perfectly on a laptop/desktop. When I try to open this app on a mobile device, either an iPad, Samsung Galaxy pad or phone, the sign in fails with the following error submitted in the logfile: ERROR - Connector: com.mendix.core.CoreException: java.lang.ClassNotFoundException Note that mobile is not enabled in my web app project. I assume that mobile enabling allows you to run a mobile app in the cloud. All I want is to run my web app, in a browser on a tablet with a working data connection.
