Re: HTTP/1.1 and Chunked transfers

Thu, 05 Jul 2007 21:18:38 -0700

Just bringing part of the discussion back here - as I don't think that when chunking is turned on in the Axis client that the request is making it to WO in the first place before getting a 411 error code.
Anyone have any ideas on this? e.g., anyone successfully using chunking transfers from a soap client? 

Thanks.

Hi there,


does anyone have any experience with receiving chunked data (or  
perhaps sending chunked requests specifying the content-length  
with Axis)?



I getting a 411 Length Required response in the client... so I'm  
trying to ascertain whether there's some commons-httpclient  
setting to have that generated when creating the requests (on the  
client side) or if something else's afoot.


Any ideas?

i.e., in the client application there's something like this:
public MainServiceSoapBindingStub mainStub() {
        if ( _stub == null ) {
                MainService_ServiceLocator serviceLocator;
                
                serviceLocator = new MainService_ServiceLocator();

		this._stub = (MainServiceSoapBindingStub)  
serviceLocator.getMainService();

                <...>
                
                if ( < enable compression condition > ) {
                        Map httpSettings;

                        // Set property to compress requests

			this._stub._setProperty(HTTPConstants.MC_GZIP_REQUEST,  
Boolean.TRUE);

                        // Tell the server it can compress responses

			this._stub._setProperty(HTTPConstants.MC_ACCEPT_GZIP,  
Boolean.TRUE);


                        // enable chunking and http 1.1
                        httpSettings = new Hashtable();

			httpSettings.put(MessageContext.HTTP_TRANSPORT_VERSION,  
HTTPConstants.HEADER_PROTOCOL_V11);
			httpSettings.put 
(HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED, Boolean.TRUE);
			this._stub._setProperty(HTTPConstants.REQUEST_HEADERS,  
httpSettings);

                }
        }
}

And the stack trace below when calling one of the webservice methods.
