I had the same problem as you. I found a new Lib called Flexjson, it works great, easier to understand, and works just fine with the latest build.
https://sourceforge.net/projects/flexjson/ I have make some suggestions for enhancements, and one fix, but overall I found this lib to be much better than Jackson. Plus, if you have a good separation of dependencies in your code, you should only have to change one place in code to use the new lib. ..Geoffrey On Oct 27, 7:00 am, thol01 <[email protected]> wrote: > Hi > > I 've a app that work perfect on the local Development App Engine (SDK > 1.2.6).
