Deploying Mirror API project to Google App Engine

Question

I have been trying to deploy the Mirror API quickstart project for Java that Google provides onto Google App Engine using Maven.
I downloaded the code from github(https://github.com/googleglass/mirror-quickstart-java) and changed the client ID and secret in the oauth.properties file.

I succeeded in making it work on localhost, by simple command

mvn jetty:run

However, I am now having problems deploying it on Google App Engine.
I added appengine-web.xml in src\main\webapp\WEB-INF\ with the following content

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <application>mirror-api-java-test1</application>
  <version>1</version>
  <threadsafe>true</threadsafe>
</appengine-web-app>

Then, I made a war file with the command

mvn war:war

and tried to deploy with the follwing command

appcfg.cmd update \target\glass-java-starter-0.1-SNAPSHOT

I get the following errors when I try it.

Please help me out!
(I use Korean version of Windows, so some characters may look weird in the error log)

From looking at the error you're getting, it appears there was some kind of encoding error in one of the bytes in the app's web.xml file. My best guess is that this came from a stray edit you made with your Korean keyboard. Though Korean is probably UTF-8 encoded just like any other language, there is plenty of precedent for non-ASCII characters causing the same error.

I would just try replacing your current web.xml file with a fresh copy from github and recompiling the project.

If that doesn't work, do some research into MalformedByteSequenceException errors and how to fix them. Seems like most people find a way to identify the errant character and delete it, or otherwise find a means to re-encode the file wholesale to UTF-8.

Thanks for your answer, but I couldn't solve the problem. Instead, I have turned to using Eclipse with plugins. – Myung-chul Sung May 26 '14 at 05:34
@Myung-chulSung Hoy did you do it using Eclipse plugins, because it keeps telling me not App Engine Project – PrivatMamtora Oct 06 '14 at 23:07
