Parameter order in servlet call to Axis service?
Dear All,
I have defined a simple web service that takes in 3 String parameters
and processes these in a string return (CheckOrder.java). I compile
with the debug option (-g) so that the parameter names are known to
the wsdl. This works OK when called from a stand-alone SOAP client.
When I use the servlet call to the web service, with named parameters
in the FORM input fields, the order of the parameters is reversed
(test.html).
Any idea why this is? If this is consistent behavior, I can work around it,
but I noticed that the parameter order is confused if used with a service
that takes in more than 10 parameters.
I am using Axis 1.1 under TOMCAT 5.0.18
Thanks,
Guido Lemoine
