Hi,

You've built your project with Java 7 and GAE only supports Java 6 at this time.  Rebuild your project with Java 6 and this error will go away.

Cheers,
Simon

Hi Gustavo

As simon says you use the java 1.6 in eclipse you go through this path :- window -> preference -> java -> compiler -> compiler compliance level -> select 1.6.
