RestletFrameworkServlet missing from M5 and snapshot builds

Hi. I'm attempting to set up a Spring-backed Restlet web application hosted in the GAE. I'd like to make use of the RestletFrameworkServlet, which is currently in the trunk of the svn: http://restlet.tigris.org/source/browse/restlet/trunk/modules/org.restlet.ext.spring/src/org/restlet/ext/spring/RestletFrameworkServlet.java?view=log
However, this class does not exist in the spring ext modules of either the M5 or SNAPSHOT build. I'd be happy to build this class on my own from trunk, but I wanted to see if this particular class was left out of the builds for a reason. Is it no longer meant to be used? ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2412200 |

Ah, yes. Thanks for pointing me to that post, Ben. I've swapped my ext.spring jar from the GAE with the one provided in the JEE version. I'll test it out tonight to see if the Servlet class works inside GAE. If it does, perhaps we should consider including it in the GAE distribution of Restlet?

Hi Cedric,
Please let us know if the Spring extension works fine on GAE and we'll include it in the Restlet edition for GAE for the next snapshot!

This seems to run fine in my local environment, but when I attempt to run directly on the app engine and access a URI mapped to my RestletFrameworkServlet, I get the following error...

So, after a quick patch to the ServerAdapter class in ext.servlet, replacing references to ServletLogger with references to java.util.logging.Logger, I was able to get past this error. Unfortunately, now when I attempt to configure the SpringRouter, I get the following error:

As I was afraid, the request scope will not work within the context of a SpringRouter. I receive the following error:

Has anyone had any success with this in GAE thusfar?

If you're injecting only ServerResources and not Restlets, Guice might work for you -- GAE says it supports Guice 2. If you must have XML configuration, though, Guice is probably not the way to go.
I haven't packaged the Restlet-Guice integration nicely, but you can download the zip archive of sources, which includes an example. See my blog entry:
I probably should put these sources in the public domain explicitly.
I'm supposed to be working on an actual Restlet extension for Guice, but it's hard finding time... --tim On Mon, Nov 2, 2009 at 12:27 PM, Cedric Hurst <[hidden email]> wrote: As I was afraid, the request scope will not work within the context of a SpringRouter. I receive the following error: |

Hi Cedric,
Regarding the ServletLogger issue, this is new to us, maybe due to a GAE upgrade.

Hello Cedric,
I've successfully tested to log from a Restlet and a ServerResource instance using the current snapshot. The following instruction simply logs a trace as expected: getLogger().warning("This is a test"); Could you try it and tell if it still fails for you?

Hi, Thierry... I have not yet had a chance to test this out, but I plan to this weekend. In the meantime, I wanted to clarify the particular scenario which was causing the error. On the latest Google App Engine code (1.2.6, I believe), I was using the Spring extension to instantiate a RestletFrameworkServlet. I received the error about a forbidden extension of java.util.logging.Logger after deploying to GAE and attempting to access to mapped url. I checked out the Restlet servlet extension from SVN and replaced references to ServletLogger with the java.util.logging.Logger, and I no longer received the error.
