Help Help Help - Axis client to .Net Service problem

[Adel Habib]

For some reason, the parameters I send from an Axis' client does not reach the .Net Service (the Service behaves as if the value of the params is zero). this is a simple Service that returns the Celsius value of a Fahrenheit input. Do you see anything wrong with my Java Client file. I am using Axis-Beta1 Here is Details: ========= I set up an Axis client to access a simple Web Service. This client can access successfully the Web service Tomcat (localhost:8080). I created a very similar Service on VS.Net ( and this works fine with its own .Net client). In other words, each of Axis and .Net work fine when both the Client and Service are on the same side. When my Axis client invokes the .Net Service, I can see in the SOAP header that the parameters are sent properly, but for some reason, the reurn value is wrong (it indicates that the input parametrs never reach the Service method (the return value of -17.77777 indicates that the input to the Service method is always zero.). In other words, there is a miscommunication between the client's parametes and the Service invocation. I am attaching here a SOAP trace, source files for client and Service, and the wsdl for the Service. Please respond promptly.
