GAE - Unable to update: com.google.appengine.tools.admin.HttpIoException:

Question

I tried to upload my test gwt app but I've just faced a quite strange error. Every time I try to upload app I get this:

Unable to update app: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=gwttestapp001&version=1.0& 500 Internal Server Error

Server Error (500) A server error has occurred.

See the deployment console for more details Unable to update app: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=gwttestapp001&version=1.0& 500 Internal Server Error

Server Error (500) A server error has occurred.

... console says this

Skipping GWT compilation since no relevant changes have occurred since the last deploy. Created staging directory at: 'C:\DOCUME~1\1\LOCALS~1\Temp\appcfg4973998929980348825.tmp' Scanning for jsp files. Scanning files on local disk.

Debugging information may be found in C:\Documents and Settings\1\Local Settings\Temp\appengine-deploy1308974562331110258.log

... and error log says this:

I just updated GAE from 1.5.2 to 1.6.2 but the error keeps going :(

How to fix it?

Answer 1

Well... I had to make my own research of this kind of problem deeper on... So I guess I finally found the problem root :S The thing is in my app version syntax;

My appengine-web.xml file was containing

<?xml version="1.0" encoding="UTF-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <application>gwttestapp001</application>
  <version>1.0</version>
</appengine-web-app>

... but according to tutorial I found the thing is "there is no way to use dots" in version spelling so I changed the content to

<?xml version="1.0" encoding="UTF-8"?>
    <appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
      <application>gwttestapp001</application>
      <version>1</version>
    </appengine-web-app>

... and all uploaded successfully :)

I hope that tip saves ones day
