If you have a very large and complex Java application, it might be easier to simply run it (unchanged) on GCE rather than attempt to shorehorn it in to App Engine's architecture. You could migrate functionality to App Engine over time.
You still have to "manage" GCE instances (they don't autoscale, etc.), but they do offer auto-migration across data centres (a pretty neat feature). If you can trim your instance size down in memory the small instances are very inexpensive.
