Google AppEngine Java - The Essential Links

I keep searching for the same websites over and over again. This is my collection essential links for Google AppEngine for Java. Using maven and low-level data-access only.

• Provided by Google
• http://code.google.com/p/googleappengine/  - on googlecode
• Early access downloads
• Entity JavaDocs 
• http://code.google.com/appengine - product homepage
• http://code.google.com/intl/de/appengine - product homepage, too
• Low-level data access
• How Entities and Indexes are Stored
• Datastore Java API Overview
• Datastore value types
• GAE/J Google Group
• Provided by third parties
• The maven-gae-plugin - it works great. Use version 0.5.3 or higher.
• GAE/J more complete class whitelist

Getting started with maven-gae-plugin and GAE/J 1.3.1:
1) Installing

• Download early access, e.g. to C:\
• Go to the download directory and type in a command prompt (as a single line):
  mvn install:install-file -DgroupId=com.google.appengine -DartifactId=appengine-java-sdk -Dversion=1.3.1 -Dpackaging=zip -Dfile=appengine-java-sdk-1.3.1.zip
• Use a local pom like the one linked here 
• Go to your projects root dir and call "mvn gae:unpack"

2) Using

• Just execute the maven goals listed at the maven-gae-plugin page
• e.g., mvn gae:run   runs the local appengine. It runs now, but I still have issues to find my local servlets...
