SOAP Fault

[Smitesh Shinde]

I am making a web service request to get following fault

<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>Server was unable to process request. --> Length cannot be less than zero.
Parameter name: length</faultstring>
<detail />
</soap:Fault>

I googled several times to know the exact reason of this without any result.I do not have option of debugging at the server,so only option remains is to determine what goes wrong in my request?
Can anyone tell me the exact/probable reason of this?

Does the request have a parameter "length" with a proper value? You can use a proxy tool like SOAPUI or tcpmon to watch request and response in transit; that will help track down malformed messages.

Thanks Ulf for immediate reply !!!

Are you talking about Content-Length header sent over HTTP or web service request has to send some parameter named length?I am very naive about this.

[Ulf Dittmer]

I'm talking about a parameter that's part of the WS request. The error seems to occur at a much higher level than HTTP.

I am constructing everything manually i.e. no web service API.It's actually SOAP over HTTP.Something like this

   

                ByteArrayOutputStream hdr_strm = new ByteArrayOutputStream();
		PrintWriter hdr_prnt_strm = new PrintWriter(new OutputStreamWriter(
			hdr_strm));
		hdr_prnt_strm.print("POST /TEServer/TEserver.asmx ");
		hdr_prnt_strm.println(TokenVersion.construct(1.1));
		hdr_prnt_strm.println(TokenHeaderField.construct("Host", host));
		hdr_prnt_strm.println(TokenHeaderField.construct("Connection", "open"));
		hdr_prnt_strm.println(TokenContentType.construct("text", "xml"));
		hdr_prnt_strm.println(TokenContentLength.construct(datas.getBytes().length));
		hdr_prnt_strm.println(TokenHeaderField.construct("SOAPAction",
			"http://harlandfs.com/pl/TransactionExchange/TESignon"));
		hdr_prnt_strm.print(TokenSeparator.construct());
		hdr_prnt_strm.flush();
		hdr_strm.write(//Actual bytes of soap request are written here);
		hdr_strm.flush();

 

Do i need to add something more?

Apparently the server expects something that your code doesn't provide. I'd look into what the server expects, starting with its WSDL -assuming it has one- and other documentation.
