Java7 is currently for Trusted Tester and you can apply at: https://docs.google.com/a/google.com/forms/viewform?id=13UvQiEjr7ob-QXMSFch5LByQN8vHa70Rl98g8ipCf9c
Soon, we'll open to everyone. Via Eclipse, you'll be able to add the --use_java7 flag to the appcfg tool in the next GPE release. For now, assuming you are a trusted tester, you'll have to build your app and use the command line tool bin/appcfg to update the application with the --use_java7 flag. If you do not want to use Java7, you need to setup the Eclipse java compiler used by your project to target a Java 6 environment by adding these 2 flags to the javac compiler arguments: -target 6 -source 6 This will create classes with the correct bytecode to run in a JVM 6 environment.
