[Axis2][SOAP]Can not output XML declaration, after other output has already been done.

Hi, there.

I always get the exception like "org.apache.axis2.AxisFault: Can not output
XML declaration, after other output has already been done.; nested exception
is: " when I try to run the following code. Does some one also meet this
AxisFault before?

you can find the Web Service here, both WSDL file, and SOAP Request and
Response sample. (I am sure, I can get the response when I using Axis1.1)

Any commonts would help me.

Thanks
Tony

Also, can you please use TCPMON to capture the actual request/response
that you are getting from Axis2.

HI, Paul

you can find the all the related source here.
http://www.xignite.com/xFutures.asmx/GetFutureSymbol

the response should like

<?xml version="1.0" encoding="utf-8" ?>
<FutureSymbol xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns="
http://www.xignite.com/services/">
<Outcome>Success</Outcome>
<Identity>IP</Identity>
<Delay>0</Delay>
<FutureSymbol>CLU2</FutureSymbol>
<CommoditySymbol>CL</CommoditySymbol>
<Year>2002</Year>
<Month>9</Month>
</FutureSymbol>

The attempt to create null QNames and null Elements appears problematic as you sub nulls for name AND prefix/localname
(note that TestingUtils has a method createDummyOMElement which accomplishes the objective implemented via)
OMElement payload = TestingUtils.createDummyOMElement();

What happens when you run the testcase supplied here

The URL you are using is not a SOAP endpoint URL.

Maybe that is what is wrong!?

Yes, I find I
Used wrong URL, and I should send the Operation instead of send whole
SOAP Envelope.

Thanks
