Hi all, When I tried to call DSS boxcaring and faced a issue when processing reply message flow.
for begin boxcar, DSS returns 202 message with content type header. HTTP/1.1 202 Accepted Set-Cookie: JSESSIONID=E6D09FBA4BEF0AE451844DE3726E28A5; Path=/; HttpOnly *Content-Type: text/xml;charset=UTF-8* Transfer-Encoding: chunked Date: Wed, 16 Oct 2013 15:10:49 GMT Server: WSO2 Carbon Server so ESB tries to parse message [2013-10-16 20:56:47,593] DEBUG - wire << "POST /services/test HTTP/1.1[\r][\n]" [2013-10-16 20:56:47,593] DEBUG - wire << "Content-Type: text/xml[\r][\n]" [2013-10-16 20:56:47,594] DEBUG - wire << "Accept: */*[\r][\n]" [2013-10-16 20:56:47,594] DEBUG - wire << "SOAPAction: "urn:begin_boxcar"[\r][\n]" [2013-10-16 20:56:47,594] DEBUG - wire << "Transfer-Encoding: chunked[\r][\n]" [2013-10-16 20:56:47,594] DEBUG - wire << "Host: localhost:9764[\r][\n]" [2013-10-16 20:56:47,594] DEBUG - wire << "Connection: Keep-Alive[\r][\n]" [2013-10-16 20:56:47,594] DEBUG - wire << "User-Agent: Synapse-PT-HttpComponents-NIO[\r][\n]" [2013-10-16 20:56:47,595] DEBUG - wire << "[\r][\n]" [2013-10-16 20:56:47,595] DEBUG - wire << "f2[\r][\n]" [2013-10-16 20:56:47,595] DEBUG - wire << "<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv=" http://schemas.xmlsoap.org/soap/envelope/";><soapenv:Body><dat:begin_boxcar xmlns:dat="http://ws.wso2.org/dataservice "></dat:begin_boxcar></soapenv:Body></soapenv:Envelope>[\r][\n]" [2013-10-16 20:56:47,595] DEBUG - wire << "0[\r][\n]" [2013-10-16 20:56:47,595] DEBUG - wire << "[\r][\n]" *[2013-10-16 20:56:47,596] DEBUG - wire >> "HTTP/1.1 202 Accepted[\r][\n]"* *[2013-10-16 20:56:47,597] DEBUG - wire >> "Set-Cookie: JSESSIONID=704569E4FED657638EC97FBF2C48BE11;

I was able to overcome this by skipping building of 202 Accepted messages. See attached diff. BTW is it fine to assume HTTP 202 response will not have a body. Spec does not tell that it's illegal but never seen a place which return http 202 with a body. Meanwhile if possible we need to fix DSS side to not send back content type header. -- Miyuru Wanninayaka Technical Lead WSO2 Inc. : http://wso2.com Mobile : +94 77 209 9788 Blog : http://miyurudw.blogspot.com Flickr : http://www.flickr.com/photos/miyuru_daminda
