Response to:�exception while running the generated code

Ajith, as per your advice I setup the TcpMon and found this SOAP request/response but still I am not sure what is wrong with the code. I am doing all the process through Ant script which got generated by

WSDL2Java -uri currencyConvert.wsdl -g -ss -sd -d xmlbeans

I tried all the options of WSDL2Java but still I am having the same problem.

Thanks
