HTTP Get Request Param and CXF Service

[Vinod D]

Hello

I am using cxf 2.1.3 SOAP/HTTP a simple service say like the one in wsdl_first 
samples with a method which takes two string params and return a string value 

String sayHi(String param1, String param2) 

I am able to invoke such a method by using HTTP Get URL as

http://my-service/sayHi?param1=arg1&param2=arg2

and see expected result. 

I am not sure how if param1 and param2 were some complex types (mapping to non 
primitive java objects), it can be supported using HTTP GET URL, without 
necessarily using JAX-RS (Rest) binding. If it is possible can someone please 
point me to an example. 

thanks very much.
