title: Google App Engine and Java Version?
body: <p>I have jre 7 installed and jdk 6u29. I can't install jre6 because an old version of it is stopping the install, I've tried removing all traces of it but it still telling me an old version is installed.</p>
  
  <p>My question is can I develop for GoogleApp engine with jdk6 and jre7 combination? I keep getting error in my logs that indicate the class was compiled with the wrong version java?</p>
