How do I rearrange input parameters to match java method signature

[to...@edbtelesciences.com]

Hei,

In our effort to integrate customer systems with the application my company 
offer, customer specification says that the order of input arguments shall 
not be important. So I have to find a solution to securing the order of 
parameters to fit Java implementation of our Web Service. I only know that 
the input parameter names will be the same as the ones in the Java
signatures. 

In addition to that it is decided that some of the parameters will be
optional, 
then I will have to supply the missing parameters myself with default values 
before Java Web Service is invoked.

How is this best done?
