java - compatability of datatypes across client and server side(both implemented in different languages) of a SOAP web srvice -

i working on soap web service(contract first approach, wsdl in place define operation parameters , datatypes). languages in client side code written , server side code written different. while working on same got below queries. have searched on net did not much help.

suppose there parameter "param" datatype "xxx". range of "xxx" datatype not match range of server side language. then, happen in case? how request parameter marshaled server side though datatype same range different?

if client side code generated in java using axis2, improve approach while making instance of stub class- each request instance of stub class should created or stub class instance should created 1 time throughout application , service calls should made using single stub instance?

does instantiation of stub create connection service prior calling service method? per knowledge not create connection till actual service phone call made , 1 time response received connection close (until http connection timeout). so?

thanks in advance.
