Hi Nacho, Did you try through the class loader ? The page http://code.google.com/appengine/docs/java/runtime.html
says: Custom Class Loading Custom class loading is fully supported under App Engine. Please be aware, though, that App Engine overrides all ClassLoaders to assign the same permissions to all classes loaded by your application. If you perform custom class loading, be cautious when loading untrusted third- party code. didier On May 21, 8:48 am, Nacho Coloma <[email protected]> wrote: > Hi, I know this is probably bad timing as most Googlers will probably > be at I/O, but anyway: > > Do I have any way to instrument a class (AKA: modify its bytecode on > class loading) inside GAE?
