RE: NPE when using WADL extension auto transform to HTML feature

RE: Problem with CookieAuthenticator
I am having the same problem as the original poster, and have been able to get CookieAuthenticator to work. Has this problem been solved? It sounds like the implementation may be incomplete. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=3026801

Intermittent Communication Error (1001) with Restlet 2.1.1
I'm seeing the following stack trace from my Restlet 2.1.1 client application when talking to my Restlet 2.1.1 server running on the GAE SDK development server. It is intermittent (sometimes the client app runs to completion), and happens on different calls.

Thank you, Thierry. I added a comment to the ticket describing my workaround (though it's probably obvious). -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=3049873
RE: Intermittent Communication Error (1001) with Restlet 2.1.1
Any ideas on this? I have not seen this when running against appspot.com, only the development server. Is the dev server running out of some resource, such as sockets? I am opening 8 simultaneous ClientResource instances in the client app, although it is single threaded (only one request outstanding at a time). Is this a bad idea? Forgot to mention in my original posting that I'm developing on CentOS 6.3. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=3049874

RE: Intermittent Communication Error (1001) with Restlet 2.1.1
No, I have not. My work has taken me away from my task on which this problem occurs, but it still exists. Any comments from the Restlet folks? Any hints on how to diagnose this further? What additional information could we post to help you help us? -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=3053162
RE: catching JSON parse errors
So, I may be missing the obvious, but if the method's precondition is that it
receives an int[], shouldn't you be doing input validation anyway?
if (userData instanceof int[] ((int[]) userData.length 0) {
return userData;
}
else {
getResponse().setStatus(Status.BAD_REQUEST);
}
Or are you looking for an out-of-band solution for many such handlers? If the
latter, you probably could implement your own derivation of Restlet Filter does
the above check, and plumb your Filter derivative upstream from your Resource.
