I am attempting to successfully execute the Serialization example GAE/GWT
application as my first full Restlet application. (I have successfully
executed a much smaller example already.)
I am running GAE 1.3.8 and GWT 2.1.0 in Helios Eclipse. I am attempting to
execute the example locally on my computer. I have not modified the code
examples in any way. I have attempted execution of the Serialization
example with Restlet 2.0.3, 2.1M1, and 2.1 Snapshot downloaded on 11/27/10.
None have been completely successful.
When running with Restlet 2.0.3, I get the getAnonymousLogger() error
previously documented on the mailing list. Therefore, as per instructions
in the mailing list, I upgraded to 2.1M1. In both 2.1M1 and 2.1 Snapshot, I
receive an error either upon initial load into the browser or upon
submission of data:

I commented out the attachDefault line to force it to run the
router.attach(path, class) function immediately following. This only causes
the same error to fall on router.attach function.
I have attempted switching the order of the classpath, renaming the GWT
org.restlet.jar, and various combinations of Restlet code against the latest
GAE/GWT code. I do not know what to try next. Your assistance is greatly
appreciated.
