Alex, one more question my problem I can't change parameter's attribute to "optional". May be you know how to do it? I use jsr 181 in my WS and a few annotations, that do not allow be make parameter optional. does wstools allows this? Thanks. With not optional parameter I should somehow figure out what a parameters that I need to past TO in assign and fill all gaps - that is quite complex task. Thanks.
