Required Length (411) - The length required by the RESTlet client

Im new for REST and create a client to send data to external hosting. Im using org.reslet.resource.ClientResource to create a client

Representation rep = new JsonRepresentation(json); rep.setMediaType(MediaType.APPLICATION_JSON); rep.setCharacterSet(CharacterSet.UTF_8); ClientResource clientResource = getClientResource(); Representation reply = clientResource.post(rep); return readResponseStream(reply, clientResource);

however i get the following error

 Exception in thread "main" Length Required (411) - Length Required at org.restlet.resource.ClientResource.handle(ClientResource.java:858) at org.restlet.resource.ClientResource.post(ClientResource.java:1197) at org.mine.client.impl.RestClient.post(RestClient.java:59)

The same code works for a receive request

 Representation reply = clientResource.get();

I am using reslet api 2.0.8. This seems like a problem in post org.restlet: posting JSON content against webservice returns HTTP 411 error (length required)

I have the following banks on the way to classes

 org.apache.commons.codec.jar org.apache.commons.logging.jar org.apache.httpclient.jar org.apache.httpcore.jar org.json.jar org.restlet.ext.json.jar org.restlet.jar

Any help would be greatly appreciated.

the problem is that GAE does not support HTTP chunked encoding, so a serialized object cannot be sent (via POST or PUT) to the GAE server. In Restlet Framework version 2.1 M4, we have a workaround that buffers an HTTP object to prevent chunk encoding. To use it, call the CustomerResource # setRequestEntityBuffering (boolean) method with a "true" value. Please note that this workaround is not required for the GWT edition.

Since you are using Restlet 2.0.8, I suggest you use the workaround posted here: http://restlet.tigris.org/issues/show_bug.cgi?id=1219
