Answer 1

I tried this and it works fine. In your error log the error is about //m0:getQuoteResponse tag in soap body. I think this is due to namespace error in your configuration. The corresponding namespace should be http://services.samples

Answer 2

Check the axis2server log.

org.apache.axis2.AxisFault: The service cannot be found for the endpoint reference (EPR) /services/SimpleStockQuoteService/ 

If this is the error.

You need to build the sample project SimpleStockQuoteService using ant. then it will deploy the sample project into the axis2server.
