Re: Parameter order in servlet call to Axis service?

[Guido Lemoine]

Further to this problem, I attach the wsdl (both with and without debug 
option at compile)
and wsdd files. Weird thing is that, after re-compile and restart of 
TOMCAT, I now get
the order as: B A C (previously C B A), whereas I would expect A B C. 
This is what I have
experienced before with longer lists of arguments (i.e. order seems to 
be fairly arbitrary).

Any help appreciated.

Subject: 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
