Hi All, I developed an adb client using the method given in the axis2 docs and it is getting compiled alright. The problem i am facing is i get "Web Services Failed" exception when i run the client.. I am using C web service and Java Client. After tracking the server logs i found that this error occurs after the server tries to deserailize the input parameters sent by the client. i monitores the soap messages using the TCPMon tool. I used a working C client and the Java Client for the same webservice.
The C client sends SOAP message - POST /axis/Calculator HTTP/1.1 Host: 127.0.0.1:8080 Content-Type: text/xml; charset=UTF-8 SOAPAction: "Calculator#add" Content-Length: 403 <?xml version='1.0' encoding='utf-8' ?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance";> <SOAP-ENV:Body> <ns1:add xmlns:ns1="http://localhost/axis/Calculator";> <in0 xsi:type="xsd:int">2</in0> <in1 xsi:type="xsd:int">4</in1> </ns1:add> </SOAP-ENV:Body> </SOAP-ENV:Envelope> The Java Client sends this SOAP message - POST /axis/Calculator HTTP/1.1 Content-Type: text/xml; charset=UTF-8 SOAPAction: "Calculator#add" User-Agent: Axis2 Host: 127.0.0.1:8080 Content-Length: 250 <?xml version='1.0' encoding='UTF-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";> <soapenv:Body> <ns1:add xmlns:ns1="http://localhost/axis/Calculator";> <in0>2</in0> <in1>3</in1> </ns1:add> </soapenv:Body> </soapenv:Envelope> There are differences in the soapenv tag - xmlns:xsi and xmlns:xsd are missing. Also the input parameters are being sent differently. I changed these things using TCPMon and resent the message and it worked fine... So now i know that the Java Client is not sending the request in the right format but dunno how to resolve this problem. Could you Help?? Please its very urgent!!! Thanks a lot!
