for Java developers, there is a remote API handler available; adding
following to your web xml file should work (disclaimer: I have not yet
personally tested this.)
<servlet>
<servlet-name>remoteapi</servlet-name>
<servlet-class>com.google.apphosting.utils.remoteapi.RemoteApiServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>remoteapi</servlet-name>
<url-pattern>/remote_api</url-pattern>
</servlet-mapping>
<security-constraint>
<web-resource-collection>
<web-resource-name>remoteapi</web-resource-name>
<url-pattern>/remote_api</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
