Hi Vijay, The reason why you're getting this error message in hosted mode is because there is an exception bubbling up from your CalendarService.getData() call that cannot be serialized across GWT RPC. What you'll want to do is either catch the exception at the service level in a custom defined exception that can be serialized on the client-side through GWT RPC, or catch the exception and take some corrective action (such as passing a sentinel String or int value back up to the client to indicate a system failure). Even better, you might want to dig into the reason why the CalendarService.getData() call is throwing an exception in the first place, but in any case you must catch this exception so that it doesn't bubble up to the client, where it can't be serialized.
You can check out more specifics about the constraints on Serializable types in GWT RPC at the link below: http://code.google.com/webtoolkit/documentation/com.google.gwt.doc.DeveloperGuide.RemoteProcedureCalls.html#SerializableTypes If you need to further troubleshoot the problem of getting exception and other object types to the client-side across GWT RPC, you're more likely to get answers on the Google Web Toolkit forums (linked below). If you want to further look into the reason why your Calendar.getData() call is throwing an exception, I suggest you post up more information for follow up here.
