Editing GAE (section)

===New Project===
The wizard creates a directory structure for the project, including a src/ directory for Java source files, and a war/ directory for compiled classes and other files for the application, libraries, configuration files, static files such as images and CSS, and other data files. The wizard also creates a servlet source file and two configuration files. The complete directory structure looks like this:

 <Project>/
   src/
     <Project>/
       server/
         <Project>Servlet.java
     META-INF/
       jdoconfig.xml
     log4j.properties
     logging.properties
   war/
     WEB-INF/
       lib/
         ...App Engine JARs...
       [[#appengine-web.xml|appengine-web.xml]]
       [[JEE#Deployment_Descriptor|web.xml]]
     index.html
