pass remote call method parameters

[Xiao-Ye Wu]

Hi ya,
   when passing parameters for method call, do the parameters have to be in 
the right order that is defined on the services side? e.g. there is a web 
service method "helloWorld(String forename, String surname)", can i pass the 
parameters in the order of 'surname' then 'forename' or does it have to 
be 'forename' and then 'surname'? if it doesn't need to be in the right 
order, how can i do that?

Thanks for any help.
