Question

I’m trying to get the Java DrEdit example running on GAE exactly as described in the instructions. I’ve gotten to the point that I can create a new "dredit" document from docs, allow the auth and get to the actual app, but I get this in the GAE logs for every operation that goes back to gdrive:

Uncaught exception from servlet
com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 OK
{
  "code" : 401,
  "errors" : [ {
    "domain" : "global",
    "location" : "Authorization",
    "locationType" : "header",
    "message" : "Login Required",
    "reason" : "required"
  } ],
  "message" : "Login Required"
}
at com.google.api.client.googleapis.json.GoogleJsonResponseException.from(GoogleJsonResponseException.java:159) 

Where I did vary from the instructions, on 7:

In the Eclipse Build Path editor for the project, add all of the JARs
in the war/WEB-INF/lib/ directory to the project’s build path.

I added the libraries under lib/dependencies as well, just adding lib left compile errors.

Answer 1

There was a bug in DrEdit Java that made it out to release, essentially skipping a check if a token was missing. The relevant change to fix this bug is here.

I think applying that change will fix the issue for you. I have also updated the guide for this sample.
