问题
Im using smartGWT v2.1 with GWT 2 and Appengine SDK 1.3.0
On localhost, everything works fine!
When I deploy everything goes fine too, without any error!
The problem is, when i access the the app it returns an blank screen. Using the firebug i saw just nocache.js missing.
ErrorLog:
GET mika.nocache.js
http://perfworker.appspot.com/Mika/mika.nocache.js
404 Not Found
perfworker.appspot.com
Just to know, the last version of smartGWT should work on AppEngine out of the box?
Thanks in advance! Cleber

I'm going to guess you're developing on Windows. NTFS, unlike nearly every other filesystem, is case-insensitive, so it'll work fine if your file or directory has one capitalization and you're accessing it with another. On every other platform, however, including the one App Engine runs on, capitalization matters: Check that you're using the same capitalization to access the file as is used to name the file.

Btw, this not only applies to SmartGwt, but to any GWT app. I would have voted on the answer above, but I don't have enough rep points yet [new user]. Changing the casing of the link in the base html page worked for me.
