I can see the problematic code in RemotingConnectionImpl createRemotingMetaData: populateHeaders(reqMessage, metadata); | clientConfig.put("chunkedLength", "1024"); | if(msgContext != null) | { | Properties epmdProps = msgContext.getEndpointMetaData().getProperties(); | String chunkSizeValue = epmdProps.getProperty("http://org.jboss.ws/http#chunksize"); | int chunkSize = chunkSizeValue == null ? -1 : Integer.valueOf(chunkSizeValue).intValue(); | if(chunkSize > 0) | { | clientConfig.put("http://org.jboss.ws/http#chunksize", chunkSizeValue); | } else | { | clientConfig.remove("chunkedLength"); | } | } It automatically puts the chunkedLength property in place any only removes it if there is a MessageContext (non null) and that MessageContext does not have the EndPointMetaData property for chunking. The only problem is that if I'm just doing a simple SOAPMessage with a URL endpoint, I don't have a MessageContext and this code gets skipped. Heiko, any thoughts?
