Not able to deploy application with GAE 1.6.1

[Deepak Singh]

Hi All,

I recently upgraded to GAE 1.6.1.

When i deploy my app through Eclipse deploy option, it gives me Invalid OATH exception.

And when i do rollback through command prompt, it gives me the following exception

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version n

umber in .class file

        at java.lang.ClassLoader.defineClass1(Native Method)

        at java.lang.ClassLoader.defineClass(ClassLoader.java:621)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:252)

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)

And, when i do the rollback using GAE 1.5.5 which i was using earlier, it does fine.

Can some one has any idea about it?

Also, Does it make any difference to the production if i deploy my app using 1.5.5 instead of 1.6.1 as i believe that production server must be using the latest version of GAE?

Thanks

Deepak

GAE 1.6.1 

I am able to deploy but rollback gives the mentioned exception.

So, for rollback i use GAE 1.5.5 and it does fine.

Thus, there is an issue to do rollback using GAE 1.6.1

Also, Does it make any difference to the production if i deploy my app using 1.6.1 and if required i rollback using  1.5.5 ?

I believe that production server must be using the latest version of GAE. Right?

Thanks

No, I mean the version number in your appengine-web.xml file. The stack trace seems to think you have a bad version.

Hi Deepak,
You might try changing the version number. I know, with Python,
I've had version numbers get screwed up and needed to change it before
the deploy would go through.

Have you recently installed JDK 7 at all?  It looks like something is either trying or has compiled one of your JSPs/classes in JDK 7.
