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

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

Maybe that is what is wrong!?

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
