A couple of other people in the group have resolved this issue by JARing up their custom classes, rather than loading them up from the WEB-INF/classes.
You'll notice that all of your errors come from class resolution or classpath scanning - it seems the file system on GAE is particularly slow, so by loading the classes from a single resource you can get much more consistent load times. The more frameworks you use with classpath scanning, the more the filesystem impacts your load times. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
