[appengine-java] Re: NullPointerException while running a new app

[anjolight]

Hi I am getting the same NullPointerException.

The challenge is that my app runs fine in my local eclipse but it
gives me this error when it's deployed to app engine. And the error
gives me very little information as to what went wrong.

What's the best way to debug the nullpointerexception with JSP?

  Hi all,

  while updating my application, I got the following stack for all
  request made on it.
  I try to deploy a really simple new application (created with Eclipse
  and its plugin) and got the same stack.

  Any idea ?

  Thanks

[appengine-java] Re: new stack traces after upgrading to SDK 1.2.5

[anjolight]

I've got the same stack trace. I reveted back to 1.2.2 due and this
exception disappeared.

 I just wanted to make sure someone was aware of this, since it
 appeared to be something new introduced with the latest SDK.
